The Nolot Suite

Home * Engine Testing * Test-Positions * The Nolot Suite

A test-suite created by Pierre Nolot, in 1994 introduced by Marc-François Baudot in rec.games.chess.

=Discussion and Results= The suite was widely discussed in the news groups by Feng-hsiung Hsu, Steven Edwards  and others.

=Bruce's Analysis= Bruce Moreland made an analysis of those hard positions : The suite contains eleven positions:

So 3, 6, and 9 are monsters and remain unsolved, if they aren't actually broken. 1, 4, and 10 are solvable, but the scores haven't been convincing yet. 11 is also findable, but it seems that the best result is a draw, so don't expect a big positive score. 8 is also solvable, but it might be found due to speculation. 2, 5, and 7 are known to be findable as wins.
