Ouch! My brain hurts!
My latest completed game at chess.com really made my brain hurt. I played the Tarrasch defence to the Queen's Gambit and won a pawn on move 20 due to an oversight by my opponent.
Despite this good start, I felt on edge for the whole game and was relieved to eventually get the win. The game is below with my comments. Constructive criticism of my play is welcome!
