Subject: Rules of check?

Author: Lenard Spencer

This question may probably be best answered by the problemists, but if what I'm
thinking is correct, it may be possible to make looking for double checks go a
lot faster than the brute force approach of looking all over the board for more
than one checker.

Has anybody seen anything written on the subject of what makes a double check a
"legal" double check?  I mean, one that can only happen in the course of a game?
 One example, for a pawn to be involved in a double check (not counting
promotions), it can only be on a capture, discovering a rook or queen behind it.

I have been looking long and hard at this, and it seems to me (of course I'm
only a 1250 OTB player) that there are only certain circumstances that will
allow a legal double check.  I would like to locate any material like this to
see whether I am right or wrong.

Thanks in advance for any help.
