[crockpot]

i don't particularly dislike any of these bluffs, provided that you are against a field that will fold hands like AAxx on the 998 board.

however, i want to make a special note on bluff 4. it is my experience that when someone bets most of the pot but not all of it, he is bluffing almost every time and is trying to make a bet size that is intimidating but does not risk as much as a full pot bet. if the rest of the field has folded i will raise this type of bet virtually every time and expect to take the pot without a fight. it's even nicer when you have some chance of winning or splitting the pot as you did in this example, and have cards that block the hand he is representing.
