its tough but the best part about online poker is for the most part its one of the most obvious games, people just always think they are gettin bluffed. He was repping the trips, no reason to think he had anything else because he would have re-raised you with a higher PP pf and he wouldnt have raised with an a-k or a-q on the flop. I think its an obvious fold, just think of all those bad beat stories, thats what I do and i remember all I have in this situation is a pair of queens, and with that board a pair of queens isnt really that powerful imo.
I fold here about 95% of the time, unless I have AMAZING read that tells
me he has nothing, and I dont care what you say, its obvious he has trips and you just need to laydown the b*tches and keep the money you still have.
