I've been playing live 1 day a week at a local casino since January and only cashed twice I'm looking for advice on these hands I've played this weekend

Blinds are 1000/2000 I'm BB with 18BBs behind 6 players at table it gets folded round to SB who's sitting with 9BBs and he automatically shoves I have A6.

Blinds are 600/1200 I'm sitting with about 35bbs on SB &UTG calls and 2 mid position call i have 7s3s suited i think I'm getting good odds to call so i do , bb checks flop comes Js,As,9h i check someone raises 2100 it gets called and i call turns 6s i check again someone raised 2000 i re raise 7000 other player fold and guy shoves for 20,000.

Blinds are 2000/4000 I'm on BB with 14bbs 6handed mid position raises it to 10000 gets folded to me i have J10 i decide to call flop comes 5,7,10

Looking for some advice for all these hands
Thanks

Hand 1 - I had exactly the same spot with same hand. I called, he showed AQ and I lost. I still think this is a call, but if villain is tight and your close to money I might rarely fold.

Hand 2 - gross spot. Think you have to call... he might do this with sets. Often your beat, but not often enough for the price. Flush over flush here you can chalk up to a cooler.

Hand 3 - I probably fold pre, but as played check shove is probably superior to leading out...

I'm not sure if this is right but i wouldn't raise turn in hand 2.

I get that we want to protect against a fourth spade but we can also just fold if it comes.

Hand 1) in a vacuum I believe this is a call. SB range is very wide here.

Hand 2) I would check-shove once I hit the flush on the turn.

Hand 3) shove on flop, why would you call pre and not like this flop?

Assuming low buy-in local casino daily tourney.

1-call
it olny gets close if you have some sick read that the snap jam is mainly Ax and pairs(and some good broadway)...but even then i think its winning, but not a lot
*so if the snap jam is weighted heavily to the strong hands AND the table is soft/tight you can fold here

2-this is kind of a tough one oop facing a 1/5pot bet w/baby flush,
ip i would always just call...oop i think you can go either way

3-i dont understand what youre question is here
just check shove...or c/r small to induce if he bets tiny...if its a rainbow flop lean towards c/r small, if theres a flush draw just check shove
