you should try all types and decide - where is your best play
cash is harder then sng and mtt
play low and micro limits - online poker is hard to beat
my mistake - when i won some i went to NL100
and lost 100$ in first hand ( i had AK flop A79 flush draw, i did cont bet and had push all in , i called and saw a flush draw. river killed me. it was shock LOL)
