Subject: Nunn's K & P suite

Author: Amir Ban

Date: 14:08:37 02/03/00


There's an article by Nunn & Friedel in the latest ICCAJ called "Brains of the
Earth" on a contest to solve 6 very hard king & pawn endings. The article says
solving this suite in 24 hours was an exceptional achievement, and Kasparov made
an amazing achievement of solving it in 45 minutes. It's also possible to
understand from the article that Hiarcs could not solve the set.

So I set up the EPD, intending to let Junior think about it all night, but I was
surprised to find that Junior (no tablebases) can find all 6 key moves in less
than 2 minutes each.

Here is the EPD:

6k1/6p1/8/4K1P1/8/7P/8/8 w - - ; bm Kf4;
k7/4p3/4p3/8/8/3P1P2/5P2/K7 w - - ; bm Kb2;
8/4p3/2kp4/4p3/6K1/5P2/3P4/8 w - - ; bm Kg5;
k7/8/1p6/p1p5/2P4K/8/PP6/8 w - - ; bm a4;
8/8/p7/8/1P6/7p/P4k1P/3K4 w - - ; bm a3;
8/5p1p/8/6k1/8/6P1/5PP1/7K w - - ; bm Kh2;

I don't quite understand it.
