at 7:13, doesn't it make more sense to move the queen's knight on c4 to e5 instead of the other knight? Moving the the queen's knight would open a diagonal for the queen and more importantly keep the king's knight in a key defensive position to protect the h2 pawn in the king's castle formation. Maybe I am overlooking something?
9:30 bishop takes b7 instead of attack with the pawn? Yes, rook would pin your bishop on the queen. But THEN you move your pawn forward and secure the bishop. Instead of just sacrificing the pawn.
