From the thread title it seems easy to assume that you came over the top and got called by some marginal hand, K6 or Q6 or something that had you crushed and ruined your night, though maybe you have a twist that you then caught an ace on a later street to take it down.
Whatever the outcome, I think that although you chucked 13.50 into this pot you should be able to walk away from it at this point as you are still well up for the night. Win some, lose some. No? It's a dilemna though as it could be any other over pair thinking he's ahead but I think its a fold based on the action.
