3/6NL 6-max: Losing when 2-4-handed

[AceHiStation]

I have a small sample size of hands at 3/6NL 6-max, 18,601 hands, but recently noticed an interesting statistic. I am playing an extremely profitable game 5-handed and 6-handed but am a losing player in 2-4-handed games. A large part of this is due to my inability to let go of a hand or bluff in a very shorthanded setting. I partially answer my own question by stating that, but I was curious if anyone else has similar statistics or anyone wanted to offer any advice on how to tweak my game a bit. I find myself raising any A in a 3 or 4-handed situation and getting myself into trouble as a result. Well, discuss away...
