Thanks for the replies. Yeah, my thinking pre-flop was dumb as I already said. He showed up with QQ so std. cooler post I guess... I actually thought a bunch of people might say "lol, river c/r from a 100NL reg is always the nuts, fold ldo".

The interesting part of this thread is that I was putting him on a very narrow range for this and you guys are giving him a much wider range (adding hands I thought he would surely raise on the flop or the turn). Dammit handreading is really hard.
