I was playing Black against Daniel and he joked that he couldn’t avoid a boring game against me because he plays 1.d4, but the game was anything but boring nonetheless.
I let Daniel know after the game that a big mistake on his part was recapturing in the center with 11.exd4 instead of 11.cxd4. After that, I should have immediately grabbed the g-pawn and confidently played for the win. Instead, I was still hedging my bets with 11…Ng6.
13…Bg5?? was the decisive blunder of the game.
I spent a long time looking at the move 18…Ne4!! which would have been decisive, but hardly necessary nor playable at a G/90 time-control.
