I feel a bit mean - this puzzle is harder. The reason the second table is there is that if you make one like that you can draw inferences, ie if something holds true for value a and value a=value b then it must be true for all fields relating to value b also. If that didnt make sense, then think of it this way - If Joe is Trekkie and Trekkie doesnt like cats then Joe doesnt like cats.

Is anyone actually trying this? I am happy to discuss even if you feel you can make little or no progress...the format of puzzle is one I originally came across under the title of "logisticals". The one puzzle I wish I could post here is a chess crossword I made many years ago but no longer have a copy of the mag it was printed in.

Okay so one worthy managed the knights tour puzzle 27 mins after I posted it. I know this one is harder but has anyone gotten anywhere with it? Has anyone attempted it? Let me know how you are getting on!

The first game (chronologically) was against Alfred McKnight in 1988, the friend from Belarus who specializes in the Bird's Opening.
The '89 game was against the Austrian, John Rubis-Hopkirk, who played the Sicilian.
In 1990 the opponent was David Ponsonby from Estonia; the Scotch Opening was played.
The Catalan was played against Sue Kingston (who is Swedish) in 1994.
Finally, the loss to Michael O'Rourke (who played the French Defense) came in 1996. O'Rourke is Latvian.

Congratulations to both Lucidish Lux (who was first) and cobra 91, who was right behind him. I was worried it would be too hard - obviously I underestimate people. Ultimately I want to get my hands on a copy of the chess crossword from all those years ago - if anyone has the old SCCM mag it was printed in I would be grateful (or even the Canadian one it was reprinted in).
As with my other puzzles listed here, I made this years ago for a Scottish postal chess mag. I have given 2 tables here - one is for the answers, the other is to make it easier to do the logical eliminations to solve it. It IS solvable, honest.
Logic Puzzle
I have a terrible memory so I write everything down on little scraps of paper. Unfortunately, my filing system underwent a major trauma (it fell off the desk) and I can't quite piece together the details of some of my correspondence chess games. Can you help? I will try to recall as much as I can, then you can tell me which openings were played by which people and when. Oh yes, and where they were living at the time - see what I mean about my memory...?
1) I vaguely remember drawing a game against someone from Estonia in 1990.
2) Michael O'Rourke beat me in 1996 but he wasn't from Belarus or Sweden.
3) Alfred McKnight definitely didn't play me in 1989.
4) Sue Kingston isn't my friend in Belarus who specialises in the Bird's Opening.
5) The Scotch Opening was played by David Ponsonby. Probably...
6) Austrian John Rubis-Hopkirk dislikes the French Defence, didn't play it.
7) I played the Catalan in 1994; my opponent wasn't from Latvia or Austria.
