E38 Nimzo-Indian: Classical, 4...c5 (5...Bxc5)

E38 Nimzo-Indian: Classical, 4...c5 (5...Bxc5)

This was a correspondence game played at the Internet Chess Club. If I recall correctly this was a game to which my opponent challenged me to. I had completely forgotten that I had left the open for correspondence games option on at the mobile app, so there was a time when I saw an e-mail from ICC saying that I was losing one of my games on time, it made my look at what the situation was on the app. Instead of resigning the game, I quickly made a move in this game. I also noticed that one of the correspondence games that I had been challenged into had been aborted by my opponent due to me not noticing that the game was ongoing.

The game below went on in a decent manner for me until I played 13...Qc8, after which my position became completely hopeless quite quickly and I had to resign after 16.Qc3. The position that started my downhill can be seen in the next diagram.

My 13th move was not the losing move, but the game continuation ended my resistance very quickly. The game continued with the moves 14.Rac1 Rd8 15.Na4 and then I played the move that was the game deciding blunder 15...Bc5. I should have protected the pawn on b6 by playing 15...Qc7 instead.
