the most i've been up in one session so far (which is usually about 2 hours or so) is like 3.5 buy-ins. i've only played like 6,000 hands at party 25NL so far though so that might get better - hopefully. my biggest pot so far was when i had about 2 buy-ins and i got 3 others all-in with my AA pre-flop. 2 had KK and 1 had AJ. 1 had about 110BB's. another had about 80BB's and another had like 40BB's. i have yet to lose a large stack.
