I won't play freerolls because the method to success is anti everything I play poker for.
Basically its join minimum 10 at a time, every hour and shove and hope. There is an excellent chance after the 1st hour is up you are maybe left in 1 with a very large stack and by reverting to solid poker have chance of going deep. Do this a few times and after a couple of hours you hopefully are well placed to go deep in 2 or 3. You cannot play TAG poker in freerolls.
There are hundreds starting over loads of sites, so there are no shortage to join.
This obviously only applies to poker sites
own freerolls and not those organised by this forum, which are a total different kettle of fish.
I have no interest in playing like this but can understand why people do it. Detest the thieves and password sharers though.
