raise about 3x the big blind on the first hand no matter what you have, everyone should fold to you... then when its to the screen telling you to press 'a' to move on, dont do anything for 10mins or so and the blinds should be raised... then just repeat the process...

once you get to 50/100 blinds people should be dropping off left and right (dont play all of these hands as theyll invariably suck out... play real poker from at the very latest 75/100)
helps if youve got a book or some tv to watch at the same time...
