1. at .5/1 limit (at least at party and somewhat on stars), i don't know how much they really notice in terms of how tight or loose you are.

2. not raising until the river? great, you've now given me correct odds to keep drawing. in other words, you make money when i make a mistake. if your raise ruins my pot odds/implied odds, but i call anyway, i've made a mistake.

if limit's going to be your game, i would highly recommend small stakes holdem by miller et al. it'll change your life.

definitely post some hand histories so we can abuse --errr i mean assist you with your play.
