People love freerolls.  The concept is simple.  You risk nothing with the hopes of winning something.  In theory, if you risk nothing, you shouldn't be disappointed when nothing comes of it.  And yet almost everyone is disappointed when we bust out.  We have invested our time and whatever skill we have against this unknown field of opponents.  We all have a competitive spirit. 

Every freeroll I play in for Poker Curious I want to do well.  It doesn't matter that I don't play NLHE regularly; PLO is my game.  It doesn't matter that I don't play tournaments, cash is my game.  It doesn't matter that I know going in that people will play wild and crazy.  I understand the dynamics.  People play sub optimally.  They are free to take their shots however they like.  It costs them nothing to test their luck.  I only control my own variables and I have to accept whatever outcome the poker gods deliver.

Today, for instance, I only played two sizable pots.  The first one I flopped a set of 10's and my opponent, who had 6.7% equity on the flop, caught his runner runner straight after the money was all in.  In the second hand, my opponent raised and I shoved all in with 10's.  They called with 5's.  They hit their two outer on the flop.  GG me.  Obviously the percentages didn't work in my favor, but in poker all you can do it put your money in with the best hand (best equity) and leave it at that. 

Freerolls are free, but the necessary mindset to handle them and the outcome of any poker situation is something we all have to continually work on.  No one likes to lose, but in any tournament, everyone is a loser, but one.  Dealing with losing is as important, or more so, than any other component of poker.
