So this is day 2 of a $350 MTT at the Isle Casino in Florida. I have 95k to start the hand and blinds are 2k 4k with a 500 ante. Table is 9 handed. I have KQ of spades in mid pos and I raise to 8k. Button covers with 150k and he flats. BB also calls with a 60k stack. Flop comes 992 rainbow one spade. BB checks and I bet 10k into 30.5 k. Button thinks for 30 seconds and calls 10k BB folds. Turn is a q bringing back door hearts, I check and button bets 25k. Button appears to be in his twenties and this is the first time I have played with him.

Brief history on villian. He flatted my mid pos open when I had a 40 bb stack in the cut off with j10 off. He checked back flop 3 ways on k107 board, called a brick turn and checked back on a brick river. I am anticipating his pre flop flatting range to be wider then most in this spot. This is also the first time I have ever played with him and he has only been at the table for 2 orbits.

Thoughts on checking vs betting turn?

Thoughts on best course of action when he bets turn? I have 77k behind on turn when he bets 25k.

Any thoughts or analysis will be greatly appreciated.
