From last night - haven't been at the table long enough to get a good read on the villians...

Party Poker 0.25/0.50 Hold'em (10 handed)

Preflop: Hero is UTG with , .
Hero raises, UTG+1 calls, 3 folds, CO calls, Button calls, 2 folds.

Flop: (9.40 SB) , , (5 players)
Hero bets, UTG+1 folds, CO raises, Button calls, Hero calls.

Without having a good read on CO, I don't want to get too crazy yet.

Turn: (7.70 BB) (4 players)
Hero bets, CO raises, Button 3-bets, Hero ????

Here they both fired raises instantaneously - I click "Bet" and it's right back to me as a 3-bet.

This decision would've been a lot easier had you 3 bet the flop, if CO caps and button calls, then you can check/fold the turn to a raise and reraise knowing you were beat. As it is, button probably has A4 and hit trips or something, so yeah I would probably fold, though at beginners tables I hear they get pretty crazy.

If your not going to 3bet the flop, at least check-raise the turn. You dont want to get crazy as you said, so why do you donk bet the turn? The way the hand was played I could probably find a turn fold here when its 2 bets back to me.
