Not to mention there's no buy-in limit on these stakes, BB/100 means nothing if they're playing above the expected stakes (happens often if the biggest stakes are relatively low).
Again, none of what you're saying is actually proof.
Even if the average hands are playing 2x or 4x above nominal stakes, that's still an outrageously high, many std-dev above elite, win rate.
Yea, it's hard to prove things generally, but I don't really feel like the standard of "proof" matters here. I'm 99.99999...% sure the guy is cheating. I'm not saying put him in jail because of it, but definitely raise the alarm and don't play with him. Would you play with him on the Stone RFID table?
Admittedly I haven't seen a ton of his hands, but just watched a few, it's not that unusual. One used as 'proof' of cheating where he plays low connectors and hits a pair with a draw to a straight, then he bluffs off a passive player with an over-pair. If he actually had the info wouldn't he fold? Dunno, seems to me he's just a pro preying on fish. His play is pretty standard for good cash players. It's his opponents that seem unusually bad, but whom observers are overrating.
- Bluffs river with 9 high, gets check raised by 6 high, 3bet jams for barely a min raise, it gets through obviously
- Check folds TPTK on the flop on a dry board when other player has a set
- Check folds top pair and a gutshot when other player has nut straight

Also, Postle's mannerisms and interviews are the most damning IMO. He's arrogant, cocky and can't explain any of his lines, not to mention has said some questionable things that actually suggest cheating.
Reading this thread at first I thought maybe he was a Victor Blom kind of character; loose aggro playing against passive amateurs (shoving 54 would give that impression). But no, he's a fucking moron who basically is giving himself away by folding monster hands or playing weak hands strongly post-flop then needling opponents and bragging about it in interviews.
As for KK, what's the hand history like? Again, heads up or multiway? Might have a read? What are the bet sizes and stack sizes?
Im not wasting any more time talking to you and i stand by my previous statement that you dont know what you are talking about.
Also, Fedor Holz once won a major tournament shoving a similar hand a few years back.
