Subject: Re: Wanted: Endgame Test Positions

Author: Jim Monaghan
Date: 06:40:57 09/07/01
Hi Peter,

I have put together a test suite from O'Kelly's book "Assess Your Chess
Fast:From Expert to Master, Book 2" which I haven't seen anywhere else. The 176
positions are middlegame combinations and endgame studies/game positions, mostly
studies. I've posted the whole thing here before, but here is only the endgame
positions:

k7/7K/NR6/8/7p/6p1/p7/8 w - - bm Nb8; id "exercise 01.01";
1K6/1P1k4/1P6/8/8/r7/2R5/8 w - - bm Rd2+; id "exercise 01.02";

So here are 112 endgame positions. It's probably not perfect as there might be
the odd duplicate solution. Perhaps these will give you a start on your own
test. From the author's introduction: "These exercises are practical ones with
which you might be confronted in an actual game and a good grasp of them will
solve your problems when these occur in front of you on the board."

I just gave the suite to Amy on my Cel 300 with 20MB hash at 15 seconds per
position.
Amy's result:


solved 75 out of 112
