OK - I've read, I've studied, I calculate pot odds, I dont play junk hands, .... I am playing really low stakes (.25/.50) NL. Mostly ring games. I come out ahead most of the time but no large gains. I managed to go from 50.00 to just over 200.00 only to lose back down again several times. I try to play solid and it works well until I get that one hand that I think may double me up and end up losing a huge pot! Ex: I called a small raise preflop with pocket J's - all under cards came (10, 7, 4 rainbow) on the flop so I bet out 2.50 , was raised to 5.00 and I called. The turn was an ace so I called and ended up putting in another 7.50 when my opponent bet because I had seen him run people off pots all night with large bets. The river was a dud and I called another 5.00 bet only to see my opponent turn up pocket 4's for trips. Should I have seen this comming?
