Training Problems
Here is a great calculation exercise from today's round of the FIDE Grand Swiss 2025. The game is Abhimanyu Mishra v Gukesh Dommaraju. White has only one winning move. Enjoy!
Find the best move for black (advanced/master). Position from https://www.chess.com/analysis/game/live/143025128348/analysis?move=46
No way a human can spot this without spending a ton of time. Is the idea that White is in a Zugzwang after h5?
It just a better endgame I think. All the lines are in the exercise so you can compare the endgames. The bishop looks badly placed on d3.

Yeah, I watched it live. When Vidit played c6, Vincent couldn’t believe it, he instantly recognized it as a blunder. Check his reaction :

Find the best move for white and try for eight minutes before reading more (intermediate/advanced). After thinking for eight minutes I had to look on the hints that was Mating net and Zwischenzug. I was also reading the instruction that helped me find the solution. "Black has a weakened king. White's queen and bishops are looking in his direction. But the piece on d6 is under attack. Retreats should be evaluated last. Look for an active game plan first!" After thinking for maybe twelve more minutes I found the solution that was worth all the effort.

What could've happened in my CoachChamps game against the legendary streamer Frank:

You let the enemy infiltrate your position in both examples. In the first one you were picking up material, while 3 pieces were attacking your king. Maybe not enough sense of danger? King and pawn endgames are super sharp, one wrong move and you're done, so it's easy to mess one up.
We start by harassing the queen, but in the end there's a small surprise
Very nice . Enjoyed that one

@Logando2805 good puzzle, I just looked for forcing moves and it worked. 10% pass rate is a bit low though.
@Valesias120 idk, is it Rxf7 and Bg2 ?
I think the puzzle is technically impossible because you don't know if Black can still castle or not. The move it wants is 1. Rd1, which I considered, but after 1... O-O Black is just better. So, I played Rxf3. When I analyzed the puzzle with the engine it said that Black was unable to castle. If Black can castle Rxf3 is the best move.
I'm answering late, but I just remembered the rule about puzzles: If the opponents' King and Rook are in their starting position and it hasn't been explicitly said that castling isn't possible, then it is possible. But in this case it wasn't possible, yet this is not stated, so it is a mistake on their behalf.
