honest to god, I had no idea what to do here, I just kinda stared at my screen and went "uh....", it was really kinda weird. I felt like folding, OOP vs a decent MP raiser in a smallish pot, with a kicker that doesnt give me more outs if im behind. But that retarded lag part of my brain was like "omg! you have A high!". This hand really made me feel like I suck at poker.
