Heres a graph of my foray into heads up play. I actually have about 2000 more hands with similar win rate but I lost them when trying to move them from my laptop.
Amazingly, this is about $130 / hr. Table selection is everything. I have no problem leaving after 5 mins if the guy appears to be pretty good because in heads up games at these stakes, 80% of the players are total fish.
If someone will tell me how to take a screen shot and then cut certain parts of it out, I will post my stat line with agression numbers and everything. I just dont want to post the entire "general" tab.
I havent been playing much lately so this graph really covers about 8 days of play, not 25 like it says. I actually think I could make more money playing like this with a MT rate of 1.2 than I can playing 3 tables of 6 max.
