Calling w/ King high

[Ulysses]

So-so 15-30 game. Pretty good, very aggressive and tricky player to my left. He's getting tired of my late position raises and is now 3-betting me w/ a very wide range of hands.

I open-raise in CO w/ KJo. He 3-bets on the button. We get heads up.

Flop 2d4d7h

I bet. He raises. I 3-bet. He calls.

Turn (2d4d7h)Qc

I check. He bets. I call.

River (2d5d7hQc)3h

I check. He bets. I call.
