If you can get to heads up in a major tournament, you have done great. I think that there is quite a bit of luck involved when heads up. By the time you get to this point, it is all about who gets the right hand at the right time. Who gets AA when the other guy has KK. This is luck. Who flops a set when the other guy flops 2 pair. This is luck. You need 2 people with two
hands willing to shove them both, and it will take luck to win this hand. Yes, there is still some
bluffing going on, but i am not sure at this point there is a whole lot to exploit.
So, if you get to the top 2 in a major tournament, you should feel pretty good about it.
