KQo Hand 2. Would You Fold This River?

[TomBrooks]

Party Poker 1/2 Hold'em (9 handed)

MP2 is a Fish: I have him at 93/0 after 31 hands. I don't remember how many hands I had on him at the time of this hand.

Preflop: Hero is MP1 with K[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/club.gif[/img].

Pretty sure I'm beat here. Why the hell else would he raise? I'm reluctant to lay down Top Pair good kicker though.

Did he call down the whole way with no pair and a Two? A2s maybe? Would he call a PF raise with 92 or 52? Probably not. Must be King-Two or A2. But if it was K2, why didn't he raise the turn when he made Two Pair? So he must have A2, Right? Fold the river, right?

Final Pot: 11.25 BB
