Not really sure. The board had two pair so you both had at least a pair of nines and a pair of sixes. If his King was higher than the highest card in your hand he would win with the best 5 cards, 9h, 9s, 6h, 6s and K of hearts if it was the high kicker.
It would help if you could share what your hole cards were.
33 - Thanks Grateful, I am new to the game thus my confusion
I think I would have bet the flop for sure.
