I am not going to accept my own answer
I cannot see a fold here. I get it is rough spot but if you are going to under rep aces then you have to call here. After two checks you have to expect Seiver would make a play at the pot. No way Seiver is putting him an AA. It only has to be 1/3 chance of a bluff for a call. Even with ICM like a 1/2 chance of a bluff.
Have a plan! If Reinkemeier was afraid of two clubs then he should have shoved the flop. Don't check the flop if you are going to fold to another club.
If Reinkemeier held the Ace of clubs to take Ax out of Seiver's range then I get checking the flop. If a club does hit then he has a draw to the nut flush. Not the stated question but I disagree with the check on the turn with on that board. It connects with both straight and flush draws that Seiver could have or represent.
Seiver could be on AQ thinking it was good and not clubs.
You are beat by a flush but like I said then don't check the flop.
Reinkemeier is only behind JK and Seiver could be bluffing here with nothing or a draw like he has. Upon review I guess Seiver could be holding QQ, 44, and 22.
Even a semi bluff KT or a pair with one club is mathematically a call.
Seveir could be doing this with a made flush and no ace but that is only KQ, T9, 98, and 87. But would he really lead out with T9 or lower.
By not raising pre the problem is there is very little to limit either player's range.
If you listen Seiver puts him on AQ or KQ and is absolutely disgusted he folded AA. Seiver has no club is why I think he made the play on the turn rather than the river as there is like 50% chance Reinkemeier has a big club.
