I made something like you, I won PO freeroll and earn 3 dollars, after this i stared playing headsups, but im a regular from 60$ HU, so i stared from 3$ to 100 dolars, but after this i play 3 tables for 30 dolars, and loose everyone, just because of bad coin flips AJ>AK
88>10/10, but good luck with you, try to use better bankroll management :P
