Ahyan Finally Defeated Me In A Competitive Chess Tournament

This finally happened. Ahyan defeated me for the first time in a competitive chess tournament despite my rating being more than 300 points than his. We are playing in 19th Henry Memorial Chess tournament today at Mechanics Chess Institute, San Francisco. This is a 5 round Swiss where after first 3 rounds both of us were at 2. Consequently I got white in 4th round against him. I gained a pawn putting some positional pressure and got greedy to get the second pawn. So I got into a long defensive position and miscalculated a pin which I thought I can defend. Well no. Ahyan piled all his pieces on the pinned Bishop despite having only 1 minute left in his clock. As it was a game in 40 with 5 seconds delay, seeing very low time in his clock, I didn’t resign until getting checkmated with the hope to flag him down on time. But we it didn’t work out for me. I have never given up any game in my life, and did my best to win. But kudos to him. Recently he had been crossing me in tactics multiple times (my chess.com puzzle rush best is 26 and Ahyan’s is 27 for example). The moves of the game is below but u will put a diagram tonight when at home. Ahyan will get some prize money if he wins the last round that we are about to head into.
