AmIBovered is a moderately tight player, he raised preflop and then called the 3 bet. On the flop, A J 6 come out and both the A J are spades. He then caps the flop and I put him on top two. Decent turn card gives me top two pair and puts out a 3rd spade so he checks and I bet. Tricky river, river is a 4th spade and he checks...My strong read on him holding AJ omits the chances of him having a flush so I go ahead and bet.
