@@Alex-rw2gy true yeah idk how a 1220 BLUNDERED A ROYAL FORK edit: WHY DO SO MANY 1200s PLAY RANDOM FLANK PAWN ADVANCES WHEN THERE'S NO CONCRETE THREAT?
Ne3 was a great move. The road to improvement now is to think more than 1-2 moves ahead. You only looked at Nxf3 and saw your opponent could recapture. Your analysis stopped there. You didn't look for forcing moves and check in that position. And, of course, Qc5+ won the bishop. If you start thinking an extra move, you'll get to 1500-1600.
Very well played in the first game! That was a very tricky opening. It's also very easy to think that all is lost when you've overlooked something but you really kept your head and navigated out of it nicely.
