That's pretty cool! Can anyone inform an amateur like me what happens at 2:14 (https://www.youtube.com/watch?v=7YWYS209ydE#t=134 https://www.youtube.com/watch?v=7YWYS209ydE#t=134) and before that as well. It seems to me that black captures his own pawn using his knight. Is that legal? EDIT: Ah, I see. White pawn captures black pawn, and the knight captures the white pawn. I just happens so fast I didn't see the white move.
