Total pot: (4.19 BB)

WTF could the villain have here that doesn't beat me for high? A busted diamond draw with no pair? His fold surprised me, but I'm happy to take the money.

(Yes, I know that if his three downcards are 3[img]/images/graemlins/diamond.gif[/img] 4[img]/images/graemlins/diamond.gif[/img] 6[img]/images/graemlins/diamond.gif[/img] the villain scoops me; but any other card combination gives me at least half the pot.)
