No, that's not quite right kraada because the turn card will, in general, take away any chance for a nut flush draw.
For example:
PlayerA: Kh6s
Board: AhJd5hKd
On the flop, PlayerA has a backdoor nut flush draw. On the turn, the Kd killed all of PlayerA's flush draws.
If the turn had been any heart, then your filter rule works. But I would like to look for cases on the flop
where a player has a backdoor nut flush draw REGARDLESS of what comes on the turn.
I don't think there is a way to do what I want using the current filter rules, but it would be nice if
Backdoor Flush Draws had their own BackDoor Flush Draw strength options.
As I noted before, some players can call very thin, with a combination of overcards, gutshots,
and backdoor flush draws. It would be nice to filter some of these weak calls more precisely.
