*People that min raise preflop and POT the flop.
*Dealers that mess up the side pot and when you correct them, "let me do my job" they say.
*People that fold the obvious best hand on the flop because there are 2 spades out and they did not want to lose to the flush. That's really their reasonning! One guy once folded JJ on KJ4 (two clubs) because he "did not want to lose to the flush".
*Asian floaters. Call call call, just waiting for you to check OOP on a scare card so they could pot it, regardless of their cards.
*People that call off half of their stack preflop or on the flop and c/f on the next street.
*People (read pessimists) that talk during the hand,
eg: flop is 722r, I check he bets I call. Turn: 10. I check, he goes "arg you got me, check". Sometimes it's their body language that gives this away. But it's okay, more free money for me.
HOWEVER, in the above example:
Flop
722,
I c/c his standard 1/3 pot c-bet
Turn:
10,
I check, he checks while shaking his head
River:
A, I bet big, he goes "arghh.. alright, here, gift" and calls your bluff with 75o or pocket 3's or some sh&t.
