[Pokey]

The converter screwed up on you. What were the positions? It looks like you are in the SB, but you're acting last in the hand. In further consideration, it looks like "BTN" was the small blind and you were the big blind. If that's the case, you can't fold this river. You've shown entirely too much weakness to lay down top set for a 2/3rds-pot raise in a blind battle. If you're terrified of the flush, fold the turn; otherwise, call the river, too. You're committed no matter what comes.

Besides, you've got the A[img]/images/graemlins/club.gif[/img] and you see the K[img]/images/graemlins/club.gif[/img] -- what flush draw are you putting him on, here? The guy is tight and aggressive; do we really think he's just completing the small blind with Q[img]/images/graemlins/club.gif[/img] J[img]/images/graemlins/club.gif[/img]? Or do we really think he's calling a 4xBB raise OOP with 5[img]/images/graemlins/club.gif[/img] 4[img]/images/graemlins/club.gif[/img]? I just find these holdings entirely too unlikely.

Count it up:

22, six combinations.
66, six combinations.
88, six combinations.
KK (slowplayed -- theoretically possible), six combinations.
Pocket pair 99-QQ, 24 combinations, but oddly played, so unlikely.

Let's say he plays pocket deuces, sixes, and eights this way all the time, and he plays 99-KK this way one time in six. That gives us 24 combinations of cards that we beat soundly.

For the flush, we have nine remaining clubs. We can rule out holdings like Q[img]/images/graemlins/club.gif[/img] 3[img]/images/graemlins/club.gif[/img] and even 4[img]/images/graemlins/club.gif[/img] 3[img]/images/graemlins/club.gif[/img]. Let's say he'll only play the suited connectors plus Q[img]/images/graemlins/club.gif[/img] T[img]/images/graemlins/club.gif[/img] this way, considering the preflop action. If that's the case, we're talking about seven likely combinations. Even without considering any total bluffs we're a 24-to-7 favorite to win in a pot that's offering us over 2.5-to-1 odds.

In fact, the pot odds at the river are so tasty that we must call even if we include every possible combination of [img]/images/graemlins/club.gif[/img] [img]/images/graemlins/club.gif[/img] in his range (36 combinations). That means we're getting 2.5-to-1 when we're going to win two times in five.

If you were going to fold this hand, it had to be on the turn. Given that you've got rockets and it's a blind-vs-blind battle, you cannot fold the turn, so you MUST call this river when you hit your set: it's a moral imperitive.
