Good play or bad play?

I have been playing poker for about a year and have been reading about strategy everywhere and anywhere i can find it. Trying to find my leaks and improving my game is my objective which leads me to a hand i played yest night at a live tourney.
This is live a mtt and the first table im playing at the table has its loose and tight mix. I see this guy over raising hands like Q4 and re raising a 3 bet all in with Q10 vs the other player and winning etc. His showdown hands werent very strong at all. we move to a different table and i continue to play my game.
so heres the situation: me and this guy are both in middle position with him to my right. Blinds are 300-600 i have about 7k in chips and he has about 6k. He raises 3k. I look down at AJo And based on his showdown range i figured his hand wasnt too strong, so i shoved with folds all around and he calls. we turn them over and he shows a pair of tens. At this point im feeling pretty confident till the flop has 10 x,x..in conclusion he takes the pot down with his set with no help from the A on the river.
So i guess my question is based on my reads was this a good call or bad? should i have waited for a better spot?

Ummm shoving over a half stack raise against villains range with AJo might be ok but given you were in mid position with several opponents still to act I wouldn't have done it.

seems fine to me. Villain's raise for 1/2 their stack seems really suspect (would seem like a big PP?). I mean why isn't he just jamming with ~10bb's?
I still just put the pile in (the 'wee' pile.. '12bb').

This is quite ok to re-shove with anyone with only 11 blinds remaining other the the most tightest of players who you think might have A,Q+ ranges..but even this with 10 blinds left, you might be shoving anyway because you will be shoving worse most times with an even smaller stack.
Flipping is standard at these points and and A,J is a monster with only 10blinds left with all the dead money out there.

Against this player by the way, it's 100% the correct play, in later position I'd be shoving him all in with A,6+ any pairs etc.

Seems like you made the correct play. You thinned the field, and got the coin flip like you expected. whether he shows tens or q 4 off again, he's still not far behind or ahead.

seems fine, don't be too confident about AJ v TT tho - you lose more often than you win

He was pot devoted,u couldn't expect him 2 fold.its a hard call,u know he plays crap but donkeys get cards too.he played strong and u wanna give him the respect of havn a hand but your recall of him says this is the one time i can catch him we all been there.sayn no is to easy now that u know the results.but if u woulda won would u be askin this question.probably not.so yea u made the right call at the wrong time.

Against this type of player you have no fold equity,but you have his range crushed, the bet sizing is odd so he may be trying to induce, but given the hands you said he is showing down with some of his inducing hands we may have dominated, players that play q4 and other trash treat KJ J10 JQ A10 etc as gold pre.make sure you note the type of hands he bets different sizes with for later. Nice hand

I probably fold and laugh at his dumb raise.
