What you have to watch for is what I call "PEA", player elimination algorithm. It occurs a good bit early, prior to breaks, on the bubble, and once in the money. You may have AA, BUT if the villain's bank is larger, say his 10k to your 1.6k, he will beat you period. Our tournaments with as many talents as we have, would last quite longer if it did not. So on the bubble, for example, you have AA and get ousted by a Q7 offsuit, you just got "pead" on. I chance to say online is 30% skill, 30% luck and 40% algorithm. Whereas real live poker which is the real true random poker, eliminates the 40% factor and becomes more a 70% skill and 30% luck.
CHEERS!
