I think I played this hand poorly. But don't know how to play otherwise. Please teach me how to play this hand... UTG is a 23/16/0.6 (50hands)... My image is loose aggressive... however I just won a pot from UTG player the previous hand... I had 88 and flopped the quad.. checked flop and bet the turn and river on 8897k board and he called down with 5s... So I dont think he's a solid player.
