raise way more preflop. as a standard amount at the microstakes, i'd make your 3bets 3x the original raise plus 1x for each caller when in position. and 4x the original raise +1x for each caller when out of position. that's not necessarily optimal. but it's a decent guideline for the micros.

you're going to get no useful advice at all really unless you provide some stats/reads for your opponent in this hand. also attempt to put him on a range on every street.
