Two NL200/NL100 hands

[Overi]

I would appreciate some advice on these hands.

1. NL100 9 handed

I'm BB, villain is MP and efective stacks are around $140. Villain is something like 25/9/3 and seems decent.

Villain opens for $2.75. Everyone folds, I reraise KK to $7,5 (yea yea, raise more). Villain 4-bets to $15, I decide to call.

Flop is 644r. Villain open pushes $125. I tank and fold.


2. NL200 9 handed

Aggro villain is on button, 30/11/3, I'm BB. Normally I don't pull stuff like this but villain was stealing every chance he got.

So everyone folds, villain raises $7 on button. SB folds, I repop to $21 with Q9s. Villain calls.

Flop is AKJ with flush draw (not mine), I cbet $25. Villain calls and I get the impression he's not exactly strong.

Turn is a rag, I think for a while and check, he checks aswell.

River is a Q putting AKJxQ on board. I feel villain has a weak ace, maybe KJ or something like that so I decide to bluff and bet $65 into $90.

Spew? Bet more? Bet turn? Check/fold flop? (fold pf...)
