has anyone got an exhaustive list of connected flops to analyse

4h6cJd

I don't have a list, sorry.

Of unpaired flops, everything apart from K83, K82, K72, and Q72 have no straight draws, so there are a LOT of 'connected' flops.
On paired boards, you need the paired cards to have at least 4 gaps for there to be no straight draw. e.g. TT5, J66, QQ7 are not connected, but KK9 and Q88 are.

That's a pretty hefty request if you are asking for a list where both any straight draw or straight is possible. Of the 22,100 total flops, 19,860 flops, or around 89% of all flops, posses a makeup where a straight or a straight draw is possible.

If you dont take suit into account enjoy!!
