I play at Partypoker
at the moment and have done so for a few months now.
A little less than 3 months ago I had a bankroll there of $32. I have built my bankroll up slowly setting little goals along the way to were it now sits at $378.
The strategy I have used is playing SNG's only and until the last few weeks only ever one SNG at a time, so I could really concentrate. At fiirst I only played the $3 ones until my bankroll grew but still never sat down at a table for more than 5% of my BR.
when playing SNG's I would sit very very tight until 4 people were eliminated (became 6 handed), then loosen up in late position and become slightly looser with every elimination until heads up where I would push with almost any two cards.
Hope this helps even a little
