It is good to learn the variety, especially the limit games as I know I used to find them tedius and take forever but having now readjusted my game I don't mind them as I find I am having more patience on the tables and vary often with limit games you won't get donked or at least not for huge amounts if you wanna play it safe with the bets.
I mostly only play the games in the round1 weekly
freerolls on Pstars, which have huge amounts of fish etc but as with most freerolls just play uber tight when all the fishies are in a frenzie
. If your looking to play for $ then try some 10 game, it has them all haha.
