I gave it a try with 20 mBTC, and I am already 90% sure that player "boiman" is a house player.
Got 2 videos of 2 absurd hand calls, where he hits on river.
An example:
I got K2 Hearts.
Flop is 8 K something, 8 and the third card is heart as well.
That player raises me several times, I am calling in hope of flush while still having K pairs.
He keeps reraising and on turn he did really big raise. I called it.
And of course another 8 hits the river.
He had 8 and something, unsuited, and not hearts.
Of course all that could be luck, but the way of raises, reraises and the almost all in prior the river, was absolutely like he knew another 8 was coming.
The other video I got is several reraises preflop, in the end I hit all in with QQ pocket. He cals with 99 pocket and of course the first card on the flop is 9..
Again all this could be unreal luck for him, but still looks strange to happen to same player in a matter of 3 minutes.
