utg raises, from my read he is really tight in early position, folds to me. I have AQ in big blind. flop K 7 7, i check and villain checks behind. turn 3, i check and he checks behind again. im thinking about trying to value bet A hi if aother under comes. river is a K for a final board of K 7 7 3 K, so no point to bet A hi i check he bets. no brain fold or call???
