White to play and win, but it is NOT that easy for Amateur programs that do not
use Nalimov or Tablebases.
Some people the first thing that they will do is to let their engines analyze
the position, and if the score get up to plus 2.03, like in move 53.Ke1 {2.03/11
4}up to 57.Kd1 {2.10/11 10},and maintain that score for over 1 minute they will
think that it is an automatic win. Well to let an engine analyze a position and
to let two engines play the same position are two different animal. Here I was
looking at the score of Movei jumping from 2.03 to plus 2.10 in an actual game
against an unknown program Greko which play the endgame very decent without
using Tablebases.
How many Amateur programs can win with white? I will let you know what unknown
amateur program held to a draw a very strong Amateur program with black.
