I would play 3 tables full buy in at 1/2NL ( $6 total) and play TIGHT VPIP<20 and PATIENT.
By tight I don't just mean the usual 11, I also mean play ONLY Button and one off button unless you have KK or AA. POSITION IS KEY, and getting reraised makes it HARD to hold onto your money. Maybe it's just me but at Micro it seems NO ONE respects 3-6x raises so if you try and raise early/mid with A/K chances are 1 in 4 you're gonna get 2-4 players with suited crap (J/7 or K/3) trying to hit the flush, and for some reason they just don't care about pot odds or someone reraising with who knows what. Or worse someone playing A/xo and hitting 2 pair on the flop. I won't go into the bad beat tales...lol
As for patience, that IMO is one of the MOST important things. I know it sucks folding mid pairs and A/J,Q,K early but the times you fold them early will give you more chances to steal later. If your good post flop you can prolly play some marginal hands from an unraised SB or BB but personally I don't mind losing my blinds to much when I play this style.
I play like this and can maybe pull 5-10 BB/100 over a 2 hour period. I know it doesn't sound very profitable, but a couple of dollars a day like this will get you up to $50 in 2 weeks or less.
Anyway I know it ain't an exciting way to play, but just my 2 cents worth
