I don't know if one of the only ones on here that after reading the hh of the 88 folding.. I actually like it.
I can't see what the guy can have here that he plays like this EXCEPT the actual nuts. He wouldn't flat JJ three way with a flushing board, so that and probably 77 is out.
How does he get to the river with

? and KK is going to reraise preflop a big % of the time....
The only hand that makes sense to call call call call call call reraise ARRIN has to be in this case the straight flush.
If your opponents range is only

or

then in this situation it seems like an easy fold... its pretty sick for him to have a bluff of any kind as a lot of people fold.
(as a self levelling expert, I think people need to just range every street and see how their equity is vs that range on the river... in this case, not good at all) IMO
