[NLTRN] Set on 3-flush board, bet the river?

[Duuzend]

I've recently switched from 6-max NL cash games to HUSNG's, playing the 22's and 33's on PS while learning the game.. So far, things are going pretty well but of course there's plenty of room for improvement. It's from a 33, BB seems pretty decent, maybe a little passive, but I haven't seen him get out of line very much.. sharkscope indicates he's a small loser over 406 HUSNG's, but he's made a decent amount in the 45-man SNG's so I'll assume he knows how to play poker (at least for a little bit [img]/images/graemlins/tongue.gif[/img]) Do you think the average 33-player will show a worse hand often enough to justify a bet? If so, how much do we bet and what's our plan if he pushes? The rest of the hand seems standard to me, any thoughts?
