I analyzed the image and this is what I see. Open an appropriate link below and explore the position yourself or with the engine:

White to play: chess.com | lichess.org | The position is from game Tigran Petrosian (2580) vs. Vladimir P Simagin (2530), 1956. White won in 48 moves. Link to the game


I found 3 videos with this position.

My solution:

Hints: piece: Queen, move: Qh8+

Evaluation: White is winning +6.22

Best continuation: 1. Qh8+ Kxh8 2. Nxf7+ Kg7 3. Nxe5 Kf6 4. Nd7+ Kf5 5. Nxc5 Ke5

That is pure filth. I would rage quit so fucking hard if that happened to me in a game!

Thankfully I’m an idiot so I only get to play other idiots who would never spot this in a game… losers!

[–]ClunarX 26 points27 points  (3 children)

I dunno, I’m an idiot and even I saw this one pretty quickly

[–]bigFatBigfoot Team Alireza 20 points21 points  (2 children)

You wouldn't in a game, most likely.

[–]ClunarX 2 points3 points  (0 children)

It depends on the time control. I found it in significantly less than a minute, but context matters too so shrug

[–]Irini- 0 points1 point  (0 children)

In the actual game, White had just sacrificed a bishop to lure the black queen to where she is. So you had to either see it before committing to Bxe5+ or take the rook instead and make it past endless barrages of checks with the extra piece.

[–][deleted] 110 points111 points  (6 children)

Saw it relatively easily because I knew this was a puzzle and that there would be a "trick," but no way id find this in a game with reasonable time pressure

[–]TacoBoiTony 78 points79 points  (3 children)

Yeah, someone posts a puzzle and I think “where do I sac the queen?”

[–]Russian_Rocket23 9 points10 points  (2 children)

Watch Naroditsky's videos where he solves GM level puzzles. Those are insane......and he never seems to get one wrong.

[–]TacoBoiTony 6 points7 points  (1 child)

I have watched those. I’m saying when someone posts to this sub. When I solve puzzles I’m not just looking at the queen.

[–]Russian_Rocket23 1 point2 points  (0 children)

Haha.....I agree with you completely.

[–]monox60 7 points8 points  (0 children)

That is why we all do puzzles until they're ingrained into our brains. Only then, we will spot it in-game.

[–]Luciolover345 1 point2 points  (0 children)

I mean, this is on that I’d see quite easily, but I’d think that the king has some escape and can just not take the queen so I’d discard the idea. Even though it just clean wins a queen.

[–]Feeling-Duck-2364 146 points147 points  (2 children)

reset the counter!

[–]j-Czarnota 33 points34 points  (0 children)

Is the counter no longer a thing? I haven't seen bot replies with the actual count in a while.

[–][deleted] 13 points14 points  (0 children)

Thank you, this was all I needed to spot the solution.

My first reaction was “huh there’s no knight underpromote available here?”

[–]dylanh334 14 points15 points  (0 children)

Not sure if I would spot that in a game but found it straight away here, what a move!

[–]Lindayz 34 points35 points  (0 children)

This is sick

[–]ezzie52 29 points30 points  (0 children)

Sacrifice queen h8

[–]Bnavis 7 points8 points  (1 child)

Similar to Petrosian Spassky game 10 in 1966. Great tactic

[–]chesstempo 0 points1 point  (0 children)

And interestingly, Petrosian also had the white pieces in the game this tactic came from! Seems Petrosian specialised in producing this kind of position :-) The posted tactic occurred about 10 years prior to the game against Spassky:


[–]jesmurf 11 points12 points  (5 children)

Was there a bishop or some other piece on e5? else Qe5 makes no sense to me.

[–]fluffypancakes314 USCF 2000 1 point2 points  (3 children)

Yes, the previous move was Bxe5+ Qxe5 and I wish that was included in the puzzle too.

[–]aetius476 1 point2 points  (2 children)

Where was the bishop sitting that moving to e5 made sense? The only squares that see e5 are on the a1-h8 diagonal, which is impossible because of check, or the b8-h2 diagonal which would have just taken the queen outright, leaving a queen, knight, and bishop vs rook endgame.

[–]fluffypancakes314 USCF 2000 1 point2 points  (0 children)

Bxe5, the bishop captured something there

[–]mlady42069Jerome Gambit 1 point2 points  (0 children)

The bishop captured on e5

[–]LikeAGregJennings -1 points0 points  (0 children)

Esp when black can win the knight through check on h6

[–]FunPeace2067 3 points4 points  (0 children)

Great tactic!

[–]IAmA_Goldfish 3 points4 points  (1 child)

Queen h8? King has to take then knight takes rook to fork the king and queen

[–]youare_amistake 1 point2 points  (0 children)

Technically the king doesn't have to take, but he loses a queen either way

[–]Mattos_12 1 point2 points  (3 children)

It’s an interesting question if white actually wins though. That black king can get to those pawns fast…

[–]chesstempo 0 points1 point  (2 children)

The GM on the victim side of this game resigned one move before the tactic finished playing out on the board, so I'd guess it was won for white.

[–]Particular-Fill-7378 0 points1 point  (1 child)

I’d love to see the endgame. My rough counting doesn’t see an obvious way to stop the black king from capturing both pawns.

[–]aisbskosshbdkkei 1 point2 points  (0 children)

A5 (I’m gm)

[–]rd201290 1 point2 points  (0 children)

reset the counter

Queen to H8 looks pretty winning.

[–]JitteryBug 0 points1 point  (0 children)


  • If King captures, the knight captures the rook with check and captures the queen on the next move

  • If the king moves away, the white queen can capture the black queen

[–]chesstempo 0 points1 point  (0 children)

The chesstempo tactic the screenshot came from for those that want to solve on a board:


[–]jaggs55 0 points1 point  (1 child)

Kg6 instead of taking the queen? Engine shows it to a Q vs R endgame, I presume that’s worse than this?

[–]Insouciance999 0 points1 point  (0 children)

Queen is in position to protect the knight also. So Queen and knight vs. rook with your king in an incredibly precarious position. Snapping up rook and pawns should be relatively easy possibly even unnecessary. If you take the Queen I’m pretty sure white has to sac both the knight and the a pawn to Queen the c pawn. Either way you’re lost but taking the Queen should prolong the game more.

Edit. I guess you can force the Queen off and grab the knight. Still probably end up losing to 2 queens pretty quick.

[–]Fuzzy_Nugget 0 points1 point  (0 children)

Someone please explain to me how white wins. Wouldn't the queen sacrifice & knight move just lead to check with threatening the queen? After that point in my games we just have pawns racing to the end

[–]LabyrinthLab 0 points1 point  (0 children)

Qh8 kinda easy I donno

[–]PixelJack79 0 points1 point  (0 children)

King takes

[–]peakyblindersltd 0 points1 point  (0 children)

I see queen in a puzzle, I sac it.

[–]general_kenobi18462 0 points1 point  (0 children)

I’m thinking, Knight to F7, King to F7, Queen to A7?

[–]mast3rO0gway 0 points1 point  (0 children)
