I keep looking at "(r5c7=6=r5c9=9=r2c9=7=r3c7-7-r5c7)" and feel I must be dense because I still read the opening as "r5c7 is 6" yet your text in your first post states "r5c7 is not 6" (or more exactly "r5c7<>6" which I read as "r5c7 not equal to 6"). Feel free to sigh and tell me to just reread posts referenced in your first reply if my questions become too annoying.

Daj -- thanks for the link. NOW I get it

That was a tough nut. My facilitator program (at sudoku-player.org)managed it with 8 guesses in a couple of minutes, but it is way beyond my novice abilities. I really enjoyed it.
