hands I am confident about are like AK, AQ, AJ. It is nice to get AA, KK, QQ, JJ of course but recently I haven't won a single hand of these high pairs.
I haven't played online poker lately but If you are going to play any kind of tournaments be solid when the blinds are low and start loosing your range when the blind are increasing and when your stack starts being short.
Maybe in freerolls you can play Bingo poker only pushing and calling with a ceirtain kind of hands.
