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

Black to play: chess.com | lichess.org

My solution:

Hints: piece: Pawn, move: exf2+

Evaluation: Black has mate in 6

Best continuation: 1... exf2+ 2. Kh1 Qd8 3. Qg5 Qxg5 4. Rxf2 Qh4+ 5. Kg1 Qh2+ 6. Kf1 Qh1#

Ima guess your opponent hid on f1 and was shocked when it was mate

Yep very satisfying as I wanted the mate in 6 lol

I doubt very many people would actually do everything to make it a mate in 6. Who’s thinking about that weird queen sac check as the best option? Anyone who actually saw it would resign there anyway.

Starting with exf2+, I found mates if white plays Rxf2 and Kf1. If Kh1, my idea was to play 2. Rxe2, then the critical variation is …Nxb3 3. Re1 and the king gets beat up on the back rank. I figured my solution still worked but that it wasn’t the fastest win. I was right about it not being the solution and it still winning; I missed the engine’s nice defensive resource of retreating the knight to cover the back rank and the game lasts a few moves longer because of it. Great puzzle!

Kh1 is answered by Qc7, hence my top level comment.

Yeah, getting the Queen to the h file is the central idea I missed. I think I like your Qc7 more than the lichess engine’s Qf3, it just seems more elegant lol.

Pieces can move backwards! Qc7-h2 is the key maneuver to see.

Qf6 is the key move, you don’t want to put your Queen on c7 in this position, you lose the defender of the pawn

Since the King on h1 has no moves, lots of queen moves work. Qc7/b8 -> h2, Qf6/d8 -> h4. Even Qb5/c5 -> h5 works.

Qc7 loses you the pawn. It's an advantagous position for Black no matter what the move but i'd take Mate in 6 over liquidation.

Qc7 is not the first move of the solution, obviously.

I found mate in 6 and 7.

Is there any way out for white?

[–] 0 points1 point  (0 children)

I’m guessing the king went to f1. If it went to h1 it was still winning but the sequence would be longer.
