Preflop
With 13BB you can either min-raise or open jam. If you min-raise, then the idea is to have some hands (like TT), that will call it off, if you get jammed on, and others that will fold. Putting in more than 25% of your stack without actually going all in is not recommended. If you are going to fold to a jam, you lose to much of your stack, so you are kind of saying, that you always have a really good hand, that you are willing to play for stacks with. And in that case why not just move in yourself? This sizing is super unbalanced, which might not be a problem in a freeroll, but against better opponents this is definitely something, you want to avoid.
Flop
Pretty perfect flop (other than flopping a set of course), and the SPR is only around 1. No more room for messing around, get it in and be done. After that the outcome just is, what it is.
