About 125 left out of 400 runners. 20k starting stack. My stack here is about 50k which was my peak. Notable stacks on table- 1 guy has over 200k, 1 guy has about 150k, the rest have 60-100k and 1-2 players with less than 50k.

800-1600bb, 200 ante- 9 handed. Last hand at this level going to break. 1-2k next.

UTG+1 stack of about 150k raises to 5k. A big raise but isn't a huge shocker in these tourneys. A lot of the recreational middle aged guys do that often in this venue. Probably fear of flopping. This guy was an ok player, not really good how we define it around here. He got lucky a few times to build that stack, but wasn't playing too bad.

Folds to me in HJ and I peel KK. I pop it to 14.8k leaving myself about 35k behind which I intend on getting in on most boards.

Flop: J 8 2 rainbow.

He checks, I bet 16k. He huffs and puffs and calls reluctantly.

Turn: 4

He checks. I rip the rest ~19k and he calls and shows JJ. Sighhhhh. Nice Hollywood on the flop bro. I flipped over my KK so fast certain I was ahead only to be showered and take the withered drive home.

Obviously a cooler based on results but any way to play this differently? I'm thinking I could've ripped it pre-flop? Is my stack large enough to go for 3-bet like I did or should I just have ripped it? I feel like if I rip he's gonna fold hands like 77 and AQ where as he's probably calling my 3-bet since he had a big stack and was a little loose. I actually considered just flatting him at the time, I don't think anyone behind was calling since the 5k was such a large open and my flat woulda looked so strong. 

Based on the action I feel my flop play was standard and the jam on the turn was mandatory but feel free to suggest alternatives.

Thanks!
