Stats of MP player 42/37 over 61 hands. 3bet 30%, foldTo3bet 17% (Once in 6 spots), ROI 3,6% at 14$ ABI over 300 games. My first impression about him - Maniac 
I was thinking about all 3 possibilities pre, but still not sure. 3bet jaming seems fine, but he is not folding to 3bets at all. Folding might be too weak since he is opening very loose. But flatting with only 18 BB does not make me happy either.
So which line pre is better?
I've chosen to call pre as I usually play cash games & I feel much better in postflop game than in preflop situations. However, I have some doubts that having short stack I should consider my post flop skills at all.
