I don't bother with the large field, low pay, free rolls. For instance, I think Merge has $25 free rolls with 1ooo entries. No thanks. I have better use for my time. I will play the forum free rolls, especially Cardschat, cause the money to player ratio allows for reasonable chance at payback. There are other forums that have $5 free rolls. Nope. Two hours to get 34 cents. That said, don't play them to get better at poker. The play you encounter has no resemblance to the play at games with money invested. Cardschat, again, is an exception. These games don't play like a donkfest. I like cardschat.
