If you have a pretty good idea of how the guy will play, check the turn. Best players to face here are the ones who make big bets as a matter of course to protect/bully - you can then raise them back knowing that they're almost certainly bluffing. Equally, if they make a smaller than normal bet, you'll be aware they might be trying to keep you playing. For other, more passive players, reverse the two choices. Get them confused - works wonders.
