we had the nut flush, how was it not a split pot?

[HalfSugar]

He has [Ad][Kd][Jd][8d][5d]
You had [Ad][Kd][8d][7d][5d]

You share the top two cards in the flush so it is all about who has the next highest card. In this case it is him with [Jd] so he wins against your [8d] which comes up short.

[Brucio]

Hm, I can't believe I've gone this long thinking that only the high card matters.

I guess I've just gotten lucky with it being a split.

Thanks
