Hand1
With only 11BB you should either push or fold. A2s with 8 players left to act is pretty marginal, and in this particular tournament its a fold. The reason is, there is no ante to fight for, and presumably a lot of players call to much, because its a freeroll. When players call to much, you need to tighten up, and a hand like A2s is especially problematic, because its either way behind or only slightly ahead.
Hand2
Especially with no antes you could open a little smaller here maybe 2,5BB. It would not have made any difference this time, but it is a better strategy in general. You have other
hands, that want to fold to a jam, and then there is no reason to lose those extra 20% chips.
