Gennerally, in STT we arrive in HU with 25bb, 20bb, 15bb... I made my HU ranges on the Holdem Resources, but i'm not sure that my range is correct. I'm losing many HU and i think that my strategy it isn't good. I'm profitable player in $5 9players KO, but i know that i can improve my HU and consequently i will have a nice ROI. Smeone for help me?
