Flop, check raise is ok since no one has AKish. If it was raised, I'd prefer to lead into the raiser here. Not that many draws(soem straights, but they should be obvious) so checkraise can't backfire too bad.
Turn: Th is an icky card, it puts out many flush and straight draws. I'd bet 250 and see what happens. If you must check raise here, do it.
River: Ick, the flush draw came in and he still led into 2 callers. He's gotta have a decent hand to be value betting here. Is this river checkraise a bluff? You really think you're good here that often? I hate every street
