villain is totally unknown to me on nl400.. all i have on him is the green marker that says he is bad..
i have green markers on like 90% of players i play either because they're really bad, or because I am cocky.. i put them cause they are posting out of position, buying in short, very weak tight, fish, CS's, steamers etc. ... all kinds of reasons.. i don't have a note on him since I lost all the notes that i had on my computer and am now making new ones.. so, marker only..

if he has something he can have a flush, he can have a king, he can have a jack, he can have 1 card missed flush and everything else in there that you can find..

so, how much should I bet says you?

SB checks ($331.50), Hero bets $56 ($353.70), SB calls $56 ($275.50)

River: ($176, 2 players)
SB checks ($275.50), Hero bets ? ($353.70),

ok.. i guess the inline stack was messed up on the river for my stack, but if you paid attention, then you see that I'd be shoving ~$350 into ~$180 and villain has ~$275 behind..

still a shove?

I don't think shoving is too much of an overbet, if he is going to call a PSB he'll call the shove here IMO.

I think either shoving or betting 100-140 (even 124 like Ice suggests) are both fine, if he has a busted flush draw he isn't calling anything while a flush or a J will both probably call your shove.

If you raised pre flop, you would have already been all in by now!
