hand I had never seen before

[cyberer]

I was playing in a tournament yesterday. I was dealt K s 6 h in the BB, check to the flop. The flop hits As 6h 4s. There is a small bet equal to the big blind. I call. the turn is the 6 of spades, giving me both trip 6s and the nut flush draw, which I had never seen happen. The river hits the 4 d, giving me the high full house, I bet high and get some callers to win the pot.
