Decision time after rivering a str8...

[chesspain]

Paradise 10+1...level 1, with blinds 5/10...

I have 5 [img]/images/graemlins/heart.gif[/img] 7 [img]/images/graemlins/heart.gif[/img] out of the BB, and the river brings:


T [img]/images/graemlins/club.gif[/img] 8 [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] 3 [img]/images/graemlins/heart.gif[/img] 9 [img]/images/graemlins/diamond.gif[/img]

The pot was unraised PF. On the flop UTG raised it to T30 in a 6-player field. On the turn, he raised it from T10 to T100 to narrow it down to himself, SB, and me. UTG and I both began the hand with T1000, whereas SB had 200 fewer chips.

Now on the river, SB checks, and with the rivered (but not nut) str8 I check, UTG bets T270 to bring the pot to T780, and SB folds...

Do you:

1) Call the bet?
2) Raise all-in?
3) Raise another T270 or so, and call a reraise all-in?
4) Raise another T270 or so, and fold to a reraise all-in?
