This is from one of my games. I overlooked a move that could have captured the queen. I thought it would be a good example to use in the puzzle feature.

This is from one of my games on Lichess. It’s a simple position with only pawns, rooks, and a king on the board. I played 47...Rab2?? I overlooked the forced checkmate sequence: 47...Rcb2+ 48. Kc1 Ra1#. It’s a good idea to memorize this by focusing on key features such as “Pigs on the 7th” and the isolated pawn.

This is from one of my actual games. After this, I played the blunder d5?? and ended up losing. Since there aren’t many pieces left, I decided to post this as a practice problem. I am currently working on an update that will allow all registered users to post problems like this freely.
