A10s, TPTK, board-pairing turn

[bhiatt]

5/10 game yesterday at Resorts EC. Table is weirdly aggressive, with 2 or 3 super-aggro types and 2 or 3 clueless fish raising hands like A2s from the blinds. I've been seated for 45 minutes or so, and while I'm not losing (yet) my image is passive and maybe even weak-tight--earlier, I folded AJs to a bet and a raise on a ragged flop, then the next hand picked up QQ, raised, then dumped it to a turn check raise on a two-king, drawless board.

3-4 limpers to me on the button, and I raise A [img]/images/graemlins/heart.gif[/img]10 [img]/images/graemlins/heart.gif[/img]. Both blinds call and we're off.

Flop is 10-7-3r, one heart. Checked to me, I bet, super-aggro in BB calls, unknown player who just sat down to my right calls.

Turn is a 3, completing the rainbow. Aggro player donks. Unknown raises. I fold.

Too passive? My plan was to raise the turn myself before the unknown player woke up. While I don't think the BB has a 3, it would suck to call 20 and then see him pop it to 30. And even if he doesn't, what about the unknown? Easy fold, right?
