But calling on flop is prob just to see what WE will do on flop, and maybe if he has a "bluff-draw".And ok, you check, he bets you call, on river you check, he goes all in, what then?? can you call?No. When you bet on turn, you get info, Call he has us, raise he really has us, fold we got the pot.. :)Thats how i see it..
