I have lost more money with JJ than any other hand. I have a profit with TT even! From that alone I'm thinking being terribly unlucky is part of why I've lost so much with JJ. I tend to win small pots with them and lose huge ones with them.
I raise from EP with JJ. I get 4 callers (a nice loose-passive table).
Flop: 8 J 6 (rainbow)
I make a standard continuation bet and get raised. I call intending to get more money on the turn. Three people are still in the pot (me, the re-raiser, and a cold-caller). Perhaps I should have capped the flop. I simply was assuming no one would call an early position raise with 97, 75, and T9, so I thought I was in the clear.
Turn: 3
I check to the raiser knowing he'll raise again. He raises, cold-caller calls, I re-raise when it gets back to me, he raises again and I cap it when it gets back to me. The entire time we have someone call call calling. I thought he was just a calling station playing some crap hand like A6.
River: 7
The only hands that can beat me are T9 and 54. If someone called a raise pre- flop, 2 bets on the flop, and 4-bets on turn with these hands I'd be very surprised. I raise, get re-raised, raise again, and then its capped. The guy call call calling never raised, so I wasn't worried about him. I was assuming the one re-raising me also had a set, which I'd beat.
Turns out the guy re-raising me had AA (way overplaying it). And the one calling all these raises? He had 54 making the str8. So this caller with 54 called 2-bets on a gutshot draw on the flop, which then became an open-ended str8 draw on the turn.
The only thing I think I could have done better is check-called the river knowing if someone had T9 and stayed, they'd beat me. That would have saved me 2-3 bets.
