Hi, just joined and hope to learn a lot from this community.

I have a question that is pretty general, but I also think there has to be a more obvious solution that I'm missing.

Let's walk through two hands from my last night's session at a $1/2 home game...

Hand 1:

HERO is BTN with AhKh

SB posts sb 1
BB posts bb 2
MP+1 raises to 15
HERO raises to 45
MP+1 calls (30)

Pot 73
The flop comes Qs 9d 2c

MP+1 bets 30
HERO raises to 90
MP+1 folds QJo face up

Hand 2:

HERO is CO with AcKc

SB posts sb 1
BB posts bb 2
MP raises to 14
HERO raises to 36
MP calls (22)

Pot 75
The flop comes Qs Jh 7d

MP bets 25
HERO raises to 60
MP calls (35)

Pot 195
The turn is the 2c

MP bets 75
HERO folds
MP tables pocket 4s

My recent attempt at figuring out how to handle donk bets when I have an uncapped range is to just raise my opponent pretty relentlessly, but it's starting to feel like spew at this point, especially in hand 2.

I'm not sure really if there's some type of better way to handle donk bets when we don't really know what villain is donking with to begin with.

Any insights into how I can overcome this?

I feel like I have two options...
1) We raise - this seems to be what's working best for me at the moment but not sure if it's correct and feels spewy at times
2) We treat it like a normal bet, call with our medium strength/showdown, raise our nutted hands and best draws, and fold the rest

For instance, though, on hand 2, immediately folding AcKc seems SO weak to just a donk bet, especially after villain tables fourth pair

Even c/c flop and c/f turn feels so weak when our range is uncapped and I think it's allowing villain to fold out our equity way too often

Any advice is greatly appreciated, thanks.
