Day 1, level 8. Blinds 400/800/75. Eight handed. I have c.35k and am in the big blind.
UTG shoves his 4,900 in (this probably isn't an awfully narrow range). Folded round to SB. SB is a tricky local player and by this I mean capable of anything, even though he generally has a level of discipline and has some level of equity when the cards are on their back. He has not long won a pot where he called 3bet pre and c/raised twice on something like 75QA and got AT to fold, before showing KK. Ace Ten man wasn't impressed, but that gives you an idea of what I mean when I say tricky.
Anyway, back to my hand. SB thinks for a while and calls the 4,900 after a think. He has about 45k total.
I look down at
I believe calling is correct, getting a little over 3/1. Dry side pot.
Flop
SB checks.
I bet 4k. Want to protect my hand. I have flatted with KJ and the Jack high flop is great, but wet.
He now check-raises to 10k (a 5k and five 1k chips, despite having other 5k chips available, if that's of any interest).
My thinking now goes:
- He isn't likely to have the same hand as me, as a bare jack would lead and the Jack of hearts is out there.
- same goes for slowplayed big pairs.
- He might well have expected me to bet more than 4k - half or more of the side pot - and then he can shove.
- in which case, with such a wet board, where he can easily have two pictures or suited cards, he has a lot of draws in the range of hands he would raise with
- He likely isn't doing this with nothing, as he knows I won't have nothing
- There's c.30k in the middle after his raise and I can shove for c.20k more, where he might be able to fold some of his draws
So, I shove and he calls with

This did not go well.
Should I have done anything differently?
Over to you.
