Flop was dry so I think the check there was ok. I'll post rest of the hand in a comment later

I would be tempted to limp in with KK, hoping BB raises. If he indeed busted out and bought back in for $80, he might be tempted to raise you, and then you can 3-bet and trap him for his whole $80.

That said, you raised and he called....good.

Checking the flop is fine. You have the board smashed. Give V a chance to steal the pot, which he didn't take.

Turn....you have to bet for value and start building the pot so that you could get his whole stack in by the river. Bet $20, full pot. If V calls, the pot would be $60 and V would have $50 behind. You would just shove pretty much any card and give V a little better than 2-1 pot odds.

Betting the turn gives V a chance to think that you're full of it and raise AI.

Pre-flop good. Flop is ultra dry and you have the nuts so I'm ok with checking back.

Pot the turn and hope he spews.
