Your move as played. Comments about the hand overall. Please keep in mind this is not your average tourn, 2 hour rounds and very deep stacked.

I discussed with RL afterwards at end of day and will post some thoughts after I hear from others.

Very meh river decision. Don't see a clear winner between call vs fold (3rd option being sick river bluff, but we probably only rep A2hh/A3hh).

Feel like checking the turn caps our river range, so that RL knows we almost never have a 2pair+ hand (I mean, if you had AQ/44/A4, checking the turn seems really bad to me...), which makes it a lot easier to pull the trigger on a river bluff. It feels like most competent Villain's would perceive our river range as being Ax at best, which is exactly what we happen to have. I dunno, when it seems really close like this, I pretty much just ask myself, if Villain knew I had this type of hand, would he expect me to call or fold?

Is there merit to 3 betting flop with top pair, ok kicker, and nut flush draw?

Want to call. Villain's line seems a little weird.

Villain's turn check is interesting because he should be betting most made hands for value (AQ, 44, AA+QQ rarely) given the action and the board. I could see it though with AJ, and AK sometimes, for pot control.

Hero's perceived calling range OTR seems pretty narrow given his flat preflop and his own turn check. Only something like AT-AJs (which may fold to river bet), A3s+A2s rarely, and nutted hands rarely.

Don't like it as much on this board and with these stack sizes. When we're behind we're usually only good for FD outs only.

This sounds like a terrible idea.

Would he expect you to 3bet AQ in this spot pre? AJ?

How much have you been squeezing in spots like this preflop?

How long did you think before calling on the flop?

How long did it take for RL to check on the turn?

Do you think he could value bet as thin as AJ?

who the hell is richard lee

Call seems to be optimal. He will sometimes show a better ace but surely there are missed FD in his range as well.
