<font color="#990066">Pot 2: 1 BB, overbet by Hero.</font>

After I played this I thought maybe I should have played it differently. Would a turn check hoping to induce a bluff been the better play? The board isnt really that scary for a free card, and if he does have the 4 or 8 I save some bets. Or am I just thinking all this because he folded? Or would it really be the higher EV play?

Check sometimes against aggressive players and raise the river, against loose/passive calling stations always bet.

I don't understand why you would raise the river. If they're bluffing, presumably they won't call, and if they've got an 8 (maybe a 4), it's going to be 3 bets.

It will be rare they have an 8 or 4, and my experience has been they will call most of the times they bet, YMMV.

Maybe it's a party thing. Maybe they just don't fold on the river with anything reasonable.
