Hello there!
Probably played bad and too risky

You probably have some advice here

I was a mid/short stack in the live game 7-handed. We had 2 very big stacks there due to insane betting in the first level. (3 double ups/rebuys already). Blinds were 25/50, startstacks were 2000 chips. People started to push around with insane betting right from the start.
I was in late position with approx 2000 chips to my disposal.
I met the villain first time but from my obseervations he was playing very loose, rarely folding and play even weaker hands.
Pre-flop:
- 1.P layer folds
- 2. Player calls
- 3. Villain: calls [~1850 chips]
- 4.-5. Players fold
- 6. hero raise to 200 [Ad,2d, ~2000 chips] (SB)
- 7. player fold (BB)
Villain calls, rest fold
Flop comes: A, Q, 10, pot is approx: 500
Villain: bets 500
Hero: re-raise 1000
Villain: all in
Hero: call
Turn: 8
River: 5
Villain shows a Q, 5 = two pair
Hero shows: A, 2 = one pair
My thought was that he most likely did not have the ace as I have seen him playing with worse, I also wanted to avoid being pushed around even with my smallish stack. He was lucky with the 5 at the end , but thinking about it the flop might have been more dangerous than it looked especially knowing that his handrange is so much wider. Other thought was that since we already had some big stacks at the table I needed to catch up some chips quickly before I get even further behind.
