First, love the site - top effort guys.
I'm wondering if it would be possible to add a conditional moving option like I used to do in the dark old days of correspondence or email chess.
i.e. if my current move as 10. Qxd8 then I could add (if 10. ... Kxd8 11. Nf6)
The sort of thing that would speed up forced or virtually forced continuations of moves.
What do you reckon ?
I guess that the continuation sequence could be hidden from the player waiting to move, such that if the move matches then the reply would auto-appear on the board.
Even 1. e4 (if 1. ... e5 then 2. Nf3) and so on.
