Deceptive play or hopeless bluff?

[jonnyUCB]

In the actual hand, I checked the river, thinking I could never sell a set (the hand I would need to be repping with the bet) to the villian. I had decided to bet 200 on any card once I called the turn bet, but wussed out when a blank came. Villian bet 150 and I folded.

He told me later he had pocket kings. He said that because I checked the river, he thought his value bet might work since if I had a better hand I would have bet there... maybe my bluff would have worked?

I guess I'll never know since I chickened out.. just one after-effect of the 2k downswing I took this weekend I guess.
