Here's an interesting tactic I thought of recently, and decided to experiment with in this hand. When an opponent makes a small or medium sized bet at a flop, make a small raise with just about anything to see how the opponent reacts. If he shows weakness (e.g., by only calling the small raise, then checking the turn, as happened in this hand), make a substantial bluff on the turn. If your opponent reraises you on the flop, then you just fold your hand with a very small loss, otherwise you've gained valuable information and have increased the size of the pot that you'll probably be able to steal relatively easily.
