What gives Ks Jh the edge over Kh Jc?

[Phil153]

(1) will win with heart flushes that aren't a J[img]/images/graemlins/heart.gif[/img] straight flush, and J[img]/images/graemlins/club.gif[/img] straight flushes

(2) will win with spade flushes that aren't a 2[img]/images/graemlins/spade.gif[/img] straight flush, and J[img]/images/graemlins/heart.gif[/img] straight flushes

So at first glance they look equivalent. The difference between (1) and (2) is that (1)'s dominant flush can be beaten by a 22 full house or quads, whereas (2)'s flushes cannot be.

[Tom1975]

Ks Jh wins on any board with four spades, but Kh Jc loses on some boards with four hearts when Ks Jh makes a straight flush.
