I am playing HU on chico too, and had the same experience against damjanoid. I could not win and I felt that something was wrong. Guys played more against him know it better. I know they are good regs and has played lot of hands.
I tried to analize these hands because I do not want to say to a move that it is bad, or good, I wanted to understand it.
At first it is possible that someone can play higher level, and make moves what is hard to understand, but in this case the player has approx "normal" stats. Damjanoid has a stat like a typical fish [high donk, min3bet]. His stats and bet sizes does not show that he is a competent player.
and
If someone calls full stack for more than 1.5k with 2nd pair no kicker, he must have at least 2-3 bad calls. But he has not.
As I remember Sunny plays with similar stats like damjanoid. I played about 300 hand against him, and do not remember the first 200, but yesterday I played vs him [of course high stakes husng
] and in the last 2 match he lost with bad calls on river, so anyway yesterday he surely didn't see the cards.
I hope tiger will do something, because I have a lot of money @ damjanoid.
