PL25: OOP Set on Flushed board

[Vecernicek]

I think I played every street incorrectly, and would like to hear criticism. Mostly, though, I want to know how you approach the river as played:

Seat 1: MP2 ($39.65 in chips)
Seat 2: MP3 ($33.05 in chips)
Seat 3: CO ($23.65 in chips)
Seat 5: BTN ($20 in chips)
Seat 6: SB ($2.40 in chips)
Seat 7: BB ($51.25 in chips)
Seat 8: UTG ($9.25 in chips)
Seat 9: HERO ($19.25 in chips)
Seat 10: MP1 ($26.50 in chips)

HERO is UTG+1 w/ 8[img]/images/graemlins/spade.gif[/img], 8[img]/images/graemlins/club.gif[/img]
