How I lost Stud8 Scoop:L

had KK10, everyone who played had low cards (3-4 people) and I raised with my 11BB stack. Kings and 10s live.

called by a couple and some low boards began to look threatening, but I had opportunity to get it heads up between myself and 1 other guy with 3 low and 3 of a flush showing after 5th street.
He bet, I re-raised to isolate against what i believed was a low draw and possibly a flush draw (this player was the bring-in and was largely stacked), and he called.
He bricked 6th with a J, and I bet again and he called, and on 7th i had less than 1 bet so i put it in and lost to flush that he hit on 7th.

On 6th he had 3 to a low and a small pair (2s or 3s or 4s i forget) + his flush draw, so I just had to avoid him hitting his flush and making two pair (if i didnt make two pair),
I also had 2 of his flush cards in the hole and had seen 3 or so out already.

29k pot, i was doing very well at one point. fairly disappointed, near 5 hours and didnt cash.
