In fairness, I wanted to block the d-pawn while exchanging pieces:
18...Bxf3? is just a blunder. Both players still had over 15 minutes, i.e. both had just played on increment.
By move 12 I was behind my opponent's clock by half a minute, and I played no "inaccuracies" despite never playing 7. Qc2 before and wanting to randomly try something new and see what happens.
I am curious whether 13. Be2 is an improvement; I guess Nc6 in the actual game forces my reply (or Qc3 stopping d4) allowing Nb4 (or Bg4) which equalizes.
