NL50: in which I play a weak tight passive chicken (TP2K)

[Smilin']

Villain is new to the table but seemed loose and aggressive postflop (over a tiny sample). We hadn't had any confrontations until now.

This is me trying out a non-standard line for pot control with a good-but-not-great hand. I don't think it worked out very well at all. All comments appreciated, but I'm specifically wondering about how the following alternative lines stack up compared to the line I took:

1) My "standard" line would be to bet say $5.50 on the flop, and (given turn card) probably check/call one normal size bet (on either turn or river) but not two (i.e., fold to a big river bet after calling a turn bet).

2) Given my flop check, Villain's bet looks weak. Should I just c/r to end the hand there (and probably check/fold if called)?

3) Given my check/call on the flop and Villain's weak turn bet, I'm thinking I've underrepped my hand and I should just call down. Anyone like a check/call on all streets?
