I consider myself a fairly decent player, but with only moderate success. I've typically do well in ring games and I've won several 180 man sng's and a couple of MTT's with small fields. But, I always get terribly unlucky in the late stages of big MTT's. I guess my main question is how can I win a big MTT if I'm always getting outdrawn?? Most of my chips are accumulated from pots with no showdown. But, the majority of the time I pick up AA or KK,... BUSTO!! Maybe I overplay my big hands?? Here are a few hands from a small tourney earlier today. These are very typical for me and very frustrating. Any advise?
