I never play cash so im nto sure what to do here. Should i slow down when he flats the check/raise? i led turn and river trying to get value out of QQ-1010. does this make sense? i probably should have just shoved the turn with my stack

you managed to get it all in on a decently safe board with KK, so it looks alright to me. However I would absolutely 4bet pre and get it all in, since it looks like he likes his hand and you don't want any scare cards for either your or him to come off.

I would usually 4bet this pre and try to get it in. Post flop is fine, I don't slowdown as long as villain is just calling. You could just shove the turn but it probably will all go in on the river anyhow so not a big deal.

People never fold after min3betting. It's some hand they like to play, something pretty and suited, or a pocketpair. Whatever it is, they hate folding with it. You're out of position aswell so it will be harder to get alot of money in postflop. I make it it $5 preflop.

As played, the flop CR is a good idea, but you can CR larger. He's either gonna fold, call, or reraise the check-raise, pretty much regardless of the size. Because you're doing it for value, you should be looking to make a large check-raise. The pot is ~$8 including your call so you can checkraise his bet + anything up to $8, which would be something like $10. This also sets up a better turn-shove size so you don't have to make 2 akwardly sized bets on the turn and river like you had to now.

yah i min 4bet here or something dumb... don't flat a min 4bet with KK... its not bad with AA, but peeling an A on the flop really hurts your equity and ability to bet for value.

yeah 4bet to 4.50-5 here.
