Today I plaid Lichess rapid game against player with nickname Jook3d. We are with similar rating which you can notice from moves we made. If I remember correctly it was some kind of French defense. I managed to win after 2 big mistakes by Jook3d. He did not put down right Pawn to capture my Knight or Bishop in scissors, but push wrong pawn forward (e4 would be better on move 11 for black than what he did f4). After that he didn't notice dangerous diagonal of his Queen and King and my Bishop didn't have any mercy and made simultaneous attack on his Queen and King after which he resigned.

Nice diagonal by white Bishop!
