I have no cat

,
but IF I have a decent hand like let's say a broadway pair I might go AI.
Freerolls is a special format, if you can double up early you can play bully style (push people around), many players do it with any holding (ridiculous)and built up a much bigger stack.
Don't be too much dissapointed, try to find something like PokerStove(there is an odds calculator also in the tools menu here),
there are free programs like this and let calculate the chances, if you were above 50 % of win time the move was correct if not the move was bad.
See here AKs vs Any 2:

You can play freerolls endless ( you don't invest money only your lifetime and nerves

) and if you did the better preflop decission you'll be the winner longterm.
Since you did not pay an entry fee it is no monetary loss, that is why many people play freerolls this way.
Make a note colour code him as luckgambler and if you ever meet this guy at another freeroll again you know what's going on.
It's an experience thing.
