I dont have this one. And there was another article in nr.6/2000, showing some results. I summarize the descriptions of the positions by John Nunn, as they were cited here (because I own this article) : 1. "...not clear if W advantage is sufficient for a win." 2. again better for W, but not clear if enough for a win. (3. was the 5 pieces queen ending, you left out). 4. Black can draw by sacrifice of "a" pawn (difficult). 5. B is better, W can hardly exchange queens. 6. tricky, but probably draw. 7. drawish, but bishop is strong of course. 8. draw, by 1. c6!! according to dvoretzky and jussupov; very hard of course. 9. draw, but Capablance missed it, so not too easy; wrong coulor of h pawn; 10. should be draw, but B is better. hard defence for W in practical game. btw, thx for the nice idea and good work with this test setting, hope these little notes help a little.
