bro if your on the button this cannot be a 3bet pot you should be 3betting AQs always not calling then if villain checks you should be betting small then over betting turn as a bluff but AQs should always be 3bet the action went raise CO you called BTN w/ AQs when you should make it around 9bbs

Again your playing to passive preflop you should be 3betting as a bluff w/ A5s not A5o not going multi way be more aggressive preflop get some range charts to study your lighting money on fire you have a weak 2pair witch should never want to be all-in you beat nothing but over pairs witch will be uncomfortable getting all-in on a board such as 567 two tone your dead to better 2pairs straights and sets already should never pot and as played when he jams you beat nothing

must be the way you wrote hand one he got lucky then just standard hand 2 yes definitely that flop check call and 3bet larger OOP around 15bbs

villain raise-open from CO , I call from button with AQs

As Stoic-Centurion947 pointed out, if it's a 3 bet pot (3BP) should write it as Co opens 3bb? Hero 3bets BU AQs 9bb or the amount of money for whatever stakes you are playing. Stack sizes are also very important. Leaving a lot of information off that is pretty important. 3BP pot in general can just bet 1/3 with range and evaluate the turn. The K96T is a better card for villain (CO) so you should be checking a lot of hands on this turn as strong as AK. You also should be 3 betting a lot of suited broadways preflop and 77+ in this formation so AK is actually going to fall low in range and better to bet with hands that can improve a bit more such as KQ, which also blocks opponent from having QJ.

Hand #2 If it's A5o just fold preflop. Not sure why you are leading bottom pair on 765 board MW. Maybe you have some hands like 86s in range or 54s? These are going to be better hands to bet than A5 which doesn't have much equity to improve when called. Again multiway (MW) should look to bet small on flop or turns when straights or flushes are possible and the pot is also MW. You are over playing your hands and not respecting the fact it is MW and the boards are dynamic.

Hand #1-Pure 3 bet AQs BTN vs CO. Not a fan of calling here. As played, stabbing vs a check is fine, checking back is fine. I would 100% stab all turns with every combo if flop went check/check and he checked turn. River I give up too. We have a little bit of showdown value here. Also, you can't c bet as the caller (only raiser can c bet).

Hand #2-Don't like the flop lead here. I would, however lead MW with stronger made hands and hands I plan to just go with (combo draws and 2pr+). Board is super wet and we want to be doing better against their continue range.
