So this villain has played relatively loose/aggressive but did not do anything crazy, just opening BU wide and stabbing frequently. Not many interesting hands going on though, except maybe the A6. I added that hand cuz it might give useful information. Again, this is mostly about the second hand, but feel free to comment on both. With the KQ, I was just completely lost on the turn cuz I didn't really want to call turn and be forced to call river as well, but c/f seems odd, too.

I would flat preflop instead of 3bet

3b is fine if villains opening wide(although i go less), i play it the same.

I think you need more than just him being loose to 3bet that hand. You want to make sure he calls the raise with dominated hands like QT, KT, etc. If not, I just flat despite him being loose.

lol nits itt. if you feel hes able to call that 3bet sizing with dominated hands or suited cards then go for it. i would probably make sizing a little smaller though.
as played fold unless youve been 3betting like a maniac and he feels you have air really often.

good fold

a6, fold pre, fold flop... either or.... like the 3bet on kq, like the cbet on flop, fold turn as played

Based on the first hand I think he has enough Qx and 9x and weirdly played draws to call turn and evaluate river.

As jackxer said, if he is calling dominated hands, 3betting pre is going to be good here. Bet smaller so that you keep in more of those dominated hands, and also to bluff cheaply in the future if it turns out that he folds to lots of 3bets.

Don't

+1

And not 3betting this hand against loose player is bad. And if he's not calling 3bets and continues to open loose just take his chips.
