[samoleus]

don't you think that an opponent who calls the flop check-raise with A-x suited (perhaps not convinced that you are not playing KK in a tricky fashion) would check back turn and river. Or perhaps a loose player who got that far with AJ. ... Also, some players on a flush draw may call the check-raise but not fire if they missed in light of such strong preflop and postflop play from Kassem.
