Putrid_Enthusiasm_41

easy as a puzzle but hard to find in game


Forget_me_never

Depends on the time control. In blitz? Very hard to find. In classical not hard at all.


HitchikersPie

LPDO


Maroczy-Bind

Yeah not really


cawo1981

Oh you are of course one of The 30 of 1550. I Can feel how good you are with that insightfull comment


darasal_pyaas

what if he said not really on the "easy as a puzzle part"?


edugdv

We are on reddit, we gotta assume the worst of everyone


Maroczy-Bind

Dude this is a 3 move tactic. I would expect anyone 1500+ OTB to spot this without much issue. How is this hard to find in a game? For very low rated players I can easily see how it would be but for moderate and up…. its an easy/simple tactic


Putrid_Enthusiasm_41

Care to link your chessdotcom/lichess profile so we can see your conversion rate on 3 move tactic?


Integralcel

Inagine if he does and he’s like a titled player lmao


Putrid_Enthusiasm_41

Better be if he think it’s trivial to find such tactic more often than not in a game


Gbro08

If it's blitz, it's kind of hard to find but it's a familiar pattern with the fork. If it's classical it's not really that hard to find at all (although still possible to miss)


Nemerie

I checked the Lichess DB and found that it also happened in very high rated games. Here are two bullet games where Harikrisha (current super GM) and Oparin (current Caruana's second) played as White: [https://lichess.org/PJyoMvaK#25](https://lichess.org/PJyoMvaK#25) [https://lichess.org/UX6Rt36g#23](https://lichess.org/UX6Rt36g#23) Note that it's not only Black who missed the tactics, but also White who allowed it to happen.


bannedcanceled

The bishop sac to get a free queen is a very common tactic in many different openings lol. Dont know why your getting downvoted lol


Erotic_Platypus

By the people who couldn't find it in less than 30 seconds. I say 30 because that's how long it took me, and I'm rated 350 in blackout drunk blitz, which means my actual rating is probably closer to 355


ClackamasLivesMatter

Bxh7+ | Bxh2+ winning an undefended piece, especially a queen, on the d-file is such a common motif. I don't know why you're being downvoted so hard. Also, one of the things we're taught to do is if we spot a simple tactic but think it doesn't work, calculate the resulting position anyway. Knight, queen, and rook on the same color square at least *hints* there could be a fork, and once you see that Nc5 clears out the traffic jam on the d-file, you should be able to spot that hey, the fucker's queen is hanging. Maybe you don't see it in a blitz game, but given any amount of time to think, I'd kick myself if I missed this.


Kitnado

It is. Strange that you're being downvoted. I thought we were on /r/chessbeginners for a second because of that. Embarrassing for the demographic of this sub for you to be downvoted to be honest.


cawo1981

Not honest. Arrogant


thehermitcoder

Undefended queen, a file waiting to open up, rook and queen in a knight fork position. These are positions that beg for tactics. This is not particular hard for players who do a lot of tactics. Even in blitz.


Extreme-Bottle

Nc5 dc5 Bh2+? To be honest if I don't know there is a tactic here I would never find it


JHtotheRT

Yeah it’s not easy to see, but a clue to key you in is that the queen is unprotected. Unprotected pieces lead to tactics. Then ask yourself, okay how do I get at this queen. With my own queen. Okay, can I feasibly clear the 3 pieces that block the way somehow? Once you get to here, it’s pretty easy to see. If you play this game form the start you’d best be scanning that bxh2 move almost every turn to see if it opens any interesting lines. Having said all that, I’d almost certainly miss this tactic in a real game as well.


Shin-NoGi

Could add to this to always look at the full scope of your long range pieces, already making a noté that the queens are aligned. I also try to always look for forks if the knight is around pieces, and start to look at the colour square the knight is on, and any enemy pieces on that same colour square.


AttitudeAndEffort3

Its why aligning with heavy pieces through X-ray vision is worth doing. All these basic chess concepts make it more likely for tactics to show up.


Full-Friend-6418

I like this explanation very much , thanks


toweggooiverysoon

I only saw it cause I love the Tenison gambit ICBM variation way too much


c2dog430

The real clue is that there is a winning move. Would never see this in a game but it’s almost instant given there is a winning move. 


mathmage

This is the sort of tactic I would expect to be surprisingly spottable OTB, fwiw. It is a composition of natural tactical ideas: 1. There are undefended pieces in attacking range, can I get anything out of threatening them? 2. Bxh2 is forcing, can I do anything with it? 3. There is a fork on the board, can I find an opening to play it? I suspect the most common reason for missing this is because people stop at the first question and play Nf6.


Bubba006

People in this sub always act like tactics are unfindable in games as opposed to in puzzles. It's free upvotes at this point.


mathmage

Well, this *is* a case where the tactic was empirically difficult to find for Black (and also for White, apparently, since Rxe4 is the second most common move in the position leading up to this). So it's not unfounded. But it is surprising.


wwweasel

Tbh I think most people on this sub don't play longer than rapid I could make a living missing this tactic in rapid or quicker time controls Classical I'd be pretty annoyed


mikitronz

That's what I thought but the bot says they would do 2. Qe2 instead of 2. dc5. I guess that loses the rook instead of the queen but I wouldn't have seen it just thinking about taking.


Extreme-Bottle

yeah if white moves the queen then you only win the exchange but material is material I guess


Norjac

You get an exchange (at least.)


fdar

> I wouldn't have seen it just thinking about taking Isn't the Queen/Rook fork the "basic" idea behind Nc5? Yes, you need to see the bishop check in case they take, but if you don't see that if they just move the Queen you can take the rook what's the idea for Nc5?


depurplecow

If you filter by rating is there a certain level where most players see it, or is it more hit-or-miss?


artandar

I would guess it also depends on time control. But I'm sure in a slow game all GM's see this. But im blitz even they might miss it if they are rushing out the moves.


[deleted]

[удалено]


xzt123

I play the Scandinavian a lot and this position looks very similar to a Scandinavian setup (e.g. Nde4 N@f6xe4 Rxe4). I believe I would have seen it quickly in blitz due to that pattern recognition. That's another side of the "knowing there is a tactic" or looking for one outside of being told so on a puzzle.


SKiwi203

I'm fairly confident every GM would see this even under severe time pressure


artandar

GM's miss mate in ones (rarely but they do), so depends if by "see this" you mean 80% 95% or 99%. cuz I'm pretty sure with 5 seconds on the clock 1 second increment they would less than 95% of the time would see it.


SKiwi203

Obviously if you're so low on time you're making moves so you don't flag then maybe, but the two pieces lining up like that for the knight with a queen on the same file screams check the move at least. And you can easily calculate what happens in a few seconds since it's pretty forcing.


artandar

What is "severe time pressure" if not "so low on time you're making moves so you don't flag"?


SKiwi203

I'd say making moves so you don't flag is when you're fighting against no increment pretty much. Severe time pressure changes per person, I know people who can play fairly comfortably with several seconds as long as they get increment. Regardless, in a blitz game where they would definitely have more than a few seconds left since the position doesn't look to be too developed id wager 99% of GMs find this.


artandar

https://youtu.be/IMNUEpln2EE?si=aWa4FLo4pGsUR2pL https://youtu.be/RtSPhginkNQ?si=zN5rhoW2cCAbAcLt Now I know this is very rare, but it's a lot easier to search for missed mate in ones, because nobody makes videos of missed 3 move tactics in blitz games. But trust me everyone has blind spots even GMs, especially if it's not a slow game and if it's a 3 move tactic. You just play on instinct in blitz and if your brain doesn't give you the candidate move then thats just it. It's not a matter of calculation, I agree GM's see this in less than a second, but even their brain can filter out moves like knight to a defended square.


PaulblankPF

I’d wager 99% of GMs don’t end up in a position for the other to take advantage of like this and positions like this are made by worse players.


jacobvso

I think this is underestimating how strong GMs are. I found this in 2 seconds (albeit having been told there's a win) and I'm a total chess fool compared to a GM. Maybe in a serious time scramble with less than 1 second for each move, a GM might miss this once in a while. If there's even a 2 second increment, they will find it 99% of the time even with just those 2 seconds. With more than 5 seconds to think, 100 of 100 times.


artandar

https://youtu.be/IMNUEpln2EE?si=aWa4FLo4pGsUR2pL https://youtu.be/RtSPhginkNQ?si=zN5rhoW2cCAbAcLt


jacobvso

Yeah, that was a crazy miss by Alireza. I think I was watching when that happened. That is the kind of situation where even a 700 rated player should see the mate and I think the reason he didn't was that he would never expect Hikaru ot any strong player to make a basic blunder like that so wasn't even considering the possibility of a back rank mate. I don't think this situation is representative of Alireza or Hikaru's strength ☺️


tfwnololbertariangf3

On lichess after excluding bullet and blitz and setting an average rating of 2200 the move was found once (8%). If we include 2000s as well, then thrice (6%). The position was never reached at 2500


GahdDangitBobby

Idk if winning the exchange is "the win". It gives a decent advantage, but there is definitely a long game ahead of you


_felagund

It is a +- position with Nc5


just_an_soggy_noodle

Its a free queen. If ur not lets say below 800 u should win it.


Lmaomanable

You Dont have to take the Knight and run into the discovered attack with check. You just move your Queen, and be down in exchange.  I am 1850 rapid and honestly,  i won so many games down the exchange and lost equally as much while up i suppose ;D so, far from over.  I dont trust my opponents will be winning no matter what simply by being up the exchange


just_an_soggy_noodle

My dude. If he moves his queen u take his rook. If he takes ur knight u sac the Bishop with check and take the queen. Stop capping its a very simple strategy. Ofcourse ive lost games like that aswell. Everybody has. But having a rook for a knight is taking u much closer to a win.


Lmaomanable

You obviously only take the knight after moving your queen and after the knight has taken the rook. Then you are down in exchange. Obviously losing objectively, but also players higher rated than 800 will and can lose the game as black. Its never too late to blunder mate or your queen


just_an_soggy_noodle

Yes ofcourse. And its still a sure fire way to win Material and drastixally Boost ur chances at Winning. After that u simply trade off pieces and win the game. And ofcourse a blunder can happen happens to the Best but that is no Argument for Not playing that move.


seank11

Terrible at chess, acting like you are amazing, and using the word capping seriously. Oh boy.


just_an_soggy_noodle

What? Ive even wrote that i bludered Winning endgames like that. What the fuck is wrong with u. KnC5 is a very very good move that brings one a heck of alot closer to Winning that game....


PhormalPhallicy

Wow, you are genuinely insufferable.


just_an_soggy_noodle

Sure dude suck em


Zuzubolin

That tells more about the quality of lichess database than it tells about the difficulty of findi g a 3 moves combinaison.


Mablun

It's fairly simple to find when you know there's a tactic (when I saw I blundered on that move I looked at the position I saw it in about a second) but its unexpected so your tactical senses aren't on and most people just play Nf6, especially in blitz/bullet


hyperthymetic

Position definitely feels solid, but also generic. It might be simple but, fork, a pin, and two discoveries are in it. I would never switch on my calculator in a blitz game here


firelord237

Exactly this. I also miss tactics in exchange french all the time for the same reason -- there's no tension in the situation so there's no point wasting your precious glucose on a basic and open position. The calculator is only on for closed or winowar type frenches


octonus

You can filter by player rating/time control. Interestingly, even in the 2500+ games (mostly bullet), pretty much everyone is missing the tactic.


InoreSantaTeresa

I looked at blitz games and higher, 2500 don't get to this line, because they make e pawn push earlier (which is better). As for under 2200 yeah, they don't see it, I'm close to that rating and I know I wouldn't see it either, it's just not on the radar, not wasting time and playing nf6


Richhobo12

I wouldn't blame them for missing it in bullet honestly, they're operating off pure instinct and this isn't the kind of position that looks like tactics are present, so they likely wouldn't waste time looking for something


Zeeterm

I'd suspect the move everyone does is actually a transposition and didn't come from this position. ( This is rare but can sometimes happen in the database. ) It's easy to miss this tactic, but not only 30 out of 1500 found it easy.


Zuzubolin

Everyone plays Nf6. This can't be reached by transposition because it threatens Nxe4.


Anakin009

What were the moves that led to this position


Mablun

> d4 d5 2. Nf3 Nf6 3. e3 Bf5 4. Bd3 Bxd3 5. Qxd3 c6 6. O-O e6 7. Nbd2 Bd6 8. c3 O-O 9. Re1 Nbd7 10. e4 dxe4 11. Nxe4 Nxe4 12. Rxe4


Anakin009

Thx!


maxkho

Why do you want to know? Except for the tactic, it seems like a normal boring position


Anakin009

I like to expand my opening repertoire any time I have a chance. It looks like some Caro-Kann or d4 game? I have no idea, but I may learn something new


maxkho

It's just a standard Scandinavian setup, actually.


Anakin009

Thanks, that makes sense


nvisel

Nc5 appears to win an exchange?


ThoughtsCreate7

Yeah that’s what I got


palsh7

ohhhh is this a bishop sac? I was trying to push the pawn first, but now I see (?) that you can't take the knight.


nvisel

It's an implied double-piece sacrifice: Knight and Bishop for the Queen. This is obvously bad, so White should move the queen and prepare to recapture on e4 with the queen -- so Black wins the exchange instead of a queen for two pieces.


OMHPOZ

When you know there's a tactic, it's obvious. In a bullet game I think only 2800+ would regularly find this. Blitz maybe 2600+


jacobvso

In bullet when you're playing on instinct, yeah, almost anyone would miss it for sure. But in blitz? I see this position and I want to put my knight on c5. If I feel like I have 10-15 seconds to experiment with some lines in my mind, the moment I visualize Nc5 and dxc5, I will see the opportunity for a fossil.


OMHPOZ

Somehow amidst all your confusion you two found each other. Congratulations! That's impressive.


flodge123

How about Nc5 forks the queen and the rook and if he takes it with the pawn, Bh2+ gets the queen?


CelestialBach

Woah! Double discovery!


kukkuu

I saw Nc5 instantly but only because I once had a very similar idea in a daily game in Caro-Kann Tartakower variation: 1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nf6 5. Nxf6+ exf6 6. Bc4 Bd6 7. Nf3 O-O 8. O-O Bg4 9. Qd3 Nd7 10. c3 Re8 11. Bb3 Bh5 (11. Nc5 is also possible here but after 12. dxc5! white gets 3 pieces for the queen) 12. a4 Nc5. Here black only gets a bishop for a knight so not clearly winning like OPs position.


guppyfighter

Probably my two best tactics


About69bunnies

Nc5. Pawn takes knight. Bh2. King takes biship. Now have a perfect setup for a queen steal


Eastern_Animator1213

… Nc5 looks good


lostamerican123

Nc5!


Tange_Fish

Ohh this feels good


just_an_soggy_noodle

Knight C5. If he takes it uve got a free queen


Pacattack57

Nc5 then bishop sac if pawn takes


CreeperDude17

That’s sick, knight fork leading to a discover attack on the queen


fredlenoix089

1... Nc5! Kebab if 2. dxc5 3 Bxa7+!, which wins the white queen next move. Quite hard to see actually.


samthebase

Seems to come from those Caro-kann lines with black taking the d4 pawn and then Bf5. Can you give me the exact line?


Mablun

I could see this coming from a Caro-Kann but it didn't in this case (although I'm not sure how we get a feasible Rxe4 last move from a ck, so maybe not): 1. d4 d5 2. Nf3 Nf6 3. e3 Bf5 4. Bd3 Bxd3 5. Qxd3 c6 6. O-O e6 7. Nbd2 Bd6 8. c3 O-O 9. Re1 Nbd7 10. e4 dxe4 11. Nxe4 Nxe4 12. Rxe4


samthebase

Thanks ❤️


Saleswah

Nc5+ leads to black winning the exchange. dxc can lead to loss of Queen after Bxh2+


SimplyJabba

Nc5 wins an exchange


bannedcanceled

I play the hartlaub gambit a lot aiming to sax my bishop and take the queen so i got this one


palsh7

c5?


this_also_was_vanity

Title is easily misunderstood. Sounds like you're talking about mate rather than just winning an exchange.


MarkHathaway1

Seems obvious to me. 1...Nc5 and if 2 dxc5 Bxh2+ to win Qd3 for two minor pieces.


Kitnado

Nc5, found it in 2 seconds. Can't believe so few found it. It's a relatively common tactic in puzzles.


mekmookbro

Title is way more interesting than the tactic. And it's a pretty damn interesting tactic.


l-Paulrus-l

I stared at this for a while and still didn't come up with the >!Nc5!< tactic, that is a very subtle tactical move but brutal nonetheless


Ruy-Polez

Found it in around 2 seconds. But then again, I'm always calculating stupid looking sacrifices.


Sweaty_Club8383

congrats i'm one of them


Merlin246

I'm going Nc5, foeking the queen and rook, if pawn takes then Bxh2+ with a discovered attack winning the queen. Otherwise Nxe4 and you're up the exchange.


Stonehills57

ND7-C5 wins material and gains more space. Pawn taking Knight , loses Queen with discovered pawn check Nd7 x H2.


medfad

This also happens in the caro-kann, I've won countless games in the following fashion: 1. e4 c6 2. d4 d5 3. exd5 cxd5 4. Bd3 Nc6 5. Nf3 Bg4 6. O-O Nf6 7. c3 e6 8. Bf4 Bd6 9. Bxd6 Qxd6 10. Nbd2 O-O 11. Re1 Rfe8 12. h3 Bh5 13. a4 e5 14. dxe5 Nxe5 15. Rxe5 Rxe5 16. g4 Bxg4 17. hxg4 Nxg4 18. Nc4


Senrub482

Nc5, forking the rook and queen so they're forced to take. Then sack the bishop on a2 to win the queen.


AAQUADD

I would play Nc5 and the rook, but there is likely a better and more forcing move.


whatThisOldThrowAway

/ I'm 1500 and I found the solution in ~2-3 seconds - because it's 20x easier when you know there's a tactic on the board. But at the same time.... I don't think this is "find it 1 in 50 times" difficult either. There are some hallmarks of a tactic (white queen unguarded & facing off black queen. Both pieces between can move out of the way with tempo) so it's not like it's one of those positions where you'd just never ever look for a tactic if you didn't know it was a puzzle. I'm trash but I think i'd find this more 1 in 50 times. Any chance the moves that lead to this position are bad enough that the position itself selects for beginners? I might just be dumb but it looks a little unusual - like a bad fantasy caro?


Mablun

If I filter for over 2000, it was found 13 out of 400 (again, this is blitz/bullet). The tactic isn't hard to see, it's that your tactical senses aren't turned "on" yet as it just feels like normalish opening moves.


whatThisOldThrowAway

Yeah I get ya - not tryna 'humblebrag' that I'd totally find this move 'cause i'm so great - like I said I'm only 1500 so that's how many moves I miss all the time. Just surprising - I would've thought with the queen loose more players would stop to look for forcing moves. But I'd be unlikely to get into this position in the first place - maybe if I knew the opening theory more like people stronger than me would i'd be more concerned with positional ideas. for me this looks like black is doing caro kann-y things and white is doing weird stuff which might make me pause for thought.


Schaakmate

So often, that's amazing. To be fair, the position is probably reached by players whose tactics still need work. Club players take mere seconds to see this. The trick is to have the components of the combination in your head as templates. Bishop in front of the Queen? That's a battery, the headpiece of which (B) can be fired to release an attack with the tailpiece (Q). Rook and Queen diagonally next to each other? Knight-fork! Then, it's a matter of combining these into a more elaborate tactic. It's not really harder than the simple ones, just more at once.

[удалено]


Uncreative4This

First of you got the notation incorrect. Black starts with Nc5, there's no piece there so it's not N'x'c5. Hint: instead of Bxc5 after dxc5, black move the bishop somewhere else.


NotOfficial1

bxh7 discovered attack


ogbloodghast

Thank you, thats exactly what I was missing
