Loosing an winning wirh AA is just mathematics. Some players have not the overview from winning percentage. If you run multiway with AA against 78suited, KK and JT suited you loosing more
hands as you win. A lots of people think why i loose, but i was favourite. Then they think, dumb player why he call wiht 78, fake software etc. but never think about that he must isolate the AA or lay down if he is not the favourite preflop. Very good players can lay down AA, bad player call down everything, as well if flush or straight is more then possible. Allways remember that you loos statistically 3 hands out of ten hands with AA. Another fact ist recognizing, you remember the bad beats the hundred hands you win, you say it was normal. After the next 10 played hands you forget this hands. Its normal, in live you didnot remember the thousands km were you drive without an accident, but the one accident in your live youll never forget.
