- 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.
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.
