TT fold preflop?

[PSW]

The game is a live ring game w/ about 8 players. blinds are 0.50/$1. I am in the CO w/ TT. We are still in the first orbit with a lot of new faces but I know from some previous experience that there is a mix of sharks and fish at the table, I just don't know who is who yet.

UTG (+0 or +1) raises about $3 and MP (1 or 2) reraises making it $6 to go. Stacks range from $20-$40 w/ mine at $18.50. I fold. Am I chicken sh*t?

Thanks,

PSW
