river play

[jba]

this is a 1/2 game on poker room, people are generally bad but not overly passive at this table. button in particular is a special kind of moron of the laggy variety - very bad.

six handed, utg and utg+1 limp, fold, button limps, hero completes sb with J9o, bb checks.

flop 5sb five ways:

hero checks, bb checks, utg bets, button calls, hero calls, bb folds.

turn we got 4 big'uns:
5[img]/images/graemlins/spade.gif[/img]
hero checks, utg bets, button calls, hero calls

river 7bbs:

It seems to me like the most likely scenarios in no particular order are a) we bet and stuff happens b) checks through c) utg bets, button calls, and we're faced with overcalling (it's basically impossible for a laggy moron to miss this board, right?) and d) utg checks and moron bets. I don't specifically remember a read on utg.
