4/180 AA in the BB

[Clover78]

Still learning the game and need to check whether a strategy I employed is reasonable given the circumstances. About 35 left, top 18 pay but I was playing to win so needed a stack.

I had approximately half the average chip stack so when I saw AA I guess I wanted to try and get maximum value. (and risk getting sucked out, double up put me back in contention, current stack had me push/folding) Villian has been very active and this is his standard opening raise. I probably appear to be weak due to some previous hands mentioned below.

Thoughts would be appreciated. (Completely wrong? Some merit?)

I had recently tried 2 steals and had to fold to an all-in reraise preflop and an all in raise post flop. I thought if MP1 had been watching he might take a shot at this pot given the BB call and I was willing to risk a free card.

Thoughts on this much appreciated. (Is it a common beginners mistake etc)
