Yeah, that's a weird puzzle. The solution isn't even winning
It gives black a huge advantage wait for the engine to evaluate
It’s winning after couple moves with SF 10
Evaluate further after one or 2 move , it's mate in 7 by black.
It's one of the puzzles where SF13 will give a much quicker solution than SF10, so depending on your browser and which one is supported you will get quite different results.
"Way above my pay grade."
It’s rating should be 3500 I think so
But engines are not always right! and I see no clear cut advantage.!
My 600-points-lower-than-this-tactic skills will try to explain the thought process.
White's biggest weakness is that its king is cramped; black can double rooks and go to h1, attacking the king. The trouble is, white's king can move to f1, and from there he has an escape square on e2. If only he didn't, there would be a threat of checkmate. So: how do we take away e2?
The knight capturing d4 would control e2, but d4 is defended by the e pawn. So instead the ugly-looking f4 is played. This move is deceptively dangerous; now if white doesn't capture, we can push the f pawn to f3 and control e2 with our pawn instead. White is forced to capture before we can push, allowing our knight to jump to the now undefended d4. But we don't want to yet.
Looks like we could just double our rooks and proceed, but there's another tactic white can use to avoid checkmate; they can play their knight to e2, and when the rook delivers check the knight can jump to g1, cutting off the attack. If black's knight captures then the king captures and escapes to e2. So how do we get around this next hurdle? It's easy if we double with the queen instead; a queen on h2 will crack the knight like an egg. So we play g5, clearing the way for Qh7.
The final question is, why g5 and not g6? Well... I don't know. But there's one more resource white has to wriggle out of checkmate. Black's pawn on g4 is controlling white kingpawns well. If white pushes the f pawn, black's g pawn advances, locking him in. However, white can first play g3, then when black doubles, play f3, opening up f2 for the single turn it will take black to get the rook and queen up there. From f2 he can escape to e3.
But hey look, our g pawn is in a position to deliver check now, while the queen and bishop support it and white's bishop is cut off by its own king. And our queen can move back to h7, cutting off all the white squares the king might want to retreat down, trapping him on the e3/f4 squares. And our bishop has a rook behind it, so if the king captures our knight (who captured the d4 pawn before we started our attack) we can play Be5+ with Qf5 checkmate threats.
I'm probably missing some moves, but that's the logic behind it; these specific pawn moves can fatally weaken the white king, while other moves leave black a piece down, struggling to defend against their own king's weakness.
