OK, in this particular case, the raiser's board is dead enough that you might look him up. Then again, the deadness of his board makes it less likely that he's bluffing, if he's paying attention at all.

Look, folding good hands in big pots for one more bet is definitely not my specialty. I have witnesses. In this case, two open pair bets and is called. Clearly, the caller has two pair beaten. For someone to now raise, he has to have a big hand, doesn't he? It would be an improbable time to bluff, since he can count on being called. If I raise here, I have the straight crushed. I think that this is true for most players. Would you raise in that spot with less than a full house against typical opposition?
