If we attack with the pawn, we force them to a weak trade, their knight for our pawn.<br/><br/>If we attack with the knight, they can basically trade them off, and force our queen out or two pawns on the f line.<br/><br/>So the knight idea certainly doesn't have my favor. The only thing we block with C3 is our knight, but we can always move that in a different way, or move the pawn up to C4 for backup later.
