I play a lot of hands, but I will never forget one hand that happened in an online ko 5.50$ tournament....there were only 23 of us in the tournament, I was the chipreader, I got AA in my hand, someone sat opposite me who pushed me all-in pre-flop, which I gave without thinking, of course, in his hand 2, 7! He immediately got two more 7s on the table, plus a 2... so I don't even know what it is I hate AA or 2-7 more... However, the answer to the question is: I think I lost the most money with AA...!
