River: Q /images/graemlins/heart.gif
UTG +1 bets $15. Combo?

This is the worst possible river. The only hand he can have that I'm beating is AJ or AT. Call this and hope to not be boned or chalk it up to variance and ride the Zeebo theorem?

Why check turn? It may look like an ugly card, but if this villain does not adjust to stack sizes (most at 25nl don't) you can stack his AT/AJ/AQ here.

Thinking about it some more, villain could have some big broadway cards. If you think he is more likely to have these than Ax, then the check is fine.

Call river.
