Quiet Moves

Discs that touch an empty square are called frontier discs. Your opponent needs to trap your frontier discs to make a move, so the more frontier discs you have, the more moves you give them. Strong players like "quiet moves" that flip only a few discs and don't add to their frontier. From this level on, leave out any move that gives away a corner.
