Had this hand come up on the weekend and I completely brain farted on
the river.  I think that the flop and turn are pretty standard but open
for opinions
(bet a little more than half pot on the turn to set up <PSB on river).  The river brings four to a straight and my natural
reaction was that it was a terrible card but I really do not think that
this card helps villain's range.  I think the only nine that he would
have is T9 or J9 and it seems unlikely that opponent has two pairs (or has
improved to two pairs).  $8 game so doubt that villain has floated me
with air or going to turn a made hand into a bluff at the river if I
check.  I am not sure if I could check fold the river but I am guessing
the question is:

SHOVE > C/C > C/F

Really
feel like I am loosing value once I check and have set up the sizing
too good to get it all in not to shove at this point.
