A hand vs Rizen in stars 109 double stack

[Mr.Poker]

Im guessing Rizen's reraising range from the SB is fairly thin in the early stages so I quite like the 4bet. From the button, it won't get nearly as much respect and gives him the opportunity to 5 bet if he wants.

Following that line,
flop, I flat call any bet
turn, check behind/call most bets unless he is pot committing himself
river, raise AI/ bet
