This is one of the worst comments I have seen on HN. I don't think you actually checked any evidence before commenting.

I have played poker professionally for more than 10 years and I am 100% sure he was cheating.

It's not that he is playing well and making good reads. Actually often he plays like shit but happens to make some correct decisions postflop. Decicions that in long run would be really bad but in those cases were perfect. One nice example is where he went allin preflop with 45o against two players who both had AK.

Please check some of the streams and come back here to comment. You can start from Doug Polk videos. If you don't see that he is cheating then you are not a winning player and probably never have been.
