[I'm not saying I could beat a computer+database every time with the Queen, but playing a computer with a database could probably convince me that it was a win for the Rook...] D P.S. With posts like this the conscientious reader is beset with difficulties. At a time when r.g.c.m seems a little quiet, does one allow this bold statement to go unchallenged? Or do you e-mail the poster (receiving reply: "you're the hundredth person to bug me in the last hour, now back off!")? Or do you chip in with a post, adding to the dismay of the poster ("not another small-minded creep crowing over me") and earning the disdain of your peers ("yes, very good, thank you Dave, didn't we see you on Mastermind, specialist subject the bleeding obvious?")? And just as you steel yourself, the uncomfortable thought occurs: is it a troll, and I will be the one crowed at? ("HA! YOU LOOSER, COULDNT RESIST TRYING TO SHOW OFF, EH? I'VE GOT YOUR NUMBER..." etc.etc for four screens) Where is Emily Postnews when you need her? -- Dave Regis &8^D* | _ | (D.Regis@exeter.ac.uk) SCHOOLS HEALTH EDUCATION UNIT | / "()/~ | Exeter University School of Education | || \_/| | "The truth is rarely pure Heavitree Road EXETER Devon EX1 2LU | ~\ / | and never simple" http://www.ex.ac.uk/~dregis/sheu.html | _|||__ | -- WILDE From info!dregis Fri Nov 22 14:00:55 GMT 1996
