"Planning" is a process which takes place in the human mind. But chess engines do not have a human mind. What works best in the human mind may not work well in a chess engine. There is also an issue as to whether or not "beautiful human chess" is, or should be, the same as "beautiful chess engine chess." Typically, [as I see it] human chess wins brilliancy prizes when the game contains stunning hard-to-find moves and plans which are hard for a human to find. But something hard for a human to find may be easy for a chess engine and visa versa. Often, test positions are presented here with the message: "How long does it take for your engine to find the correct move?" Occasionally, one of those test positions presents exceptional difficulties for all or most of the current chess engines. If one engine finds the correct move in a short time, all the programmers should stand up and salute and award a "brilliant move" prize to the good engine. Suppose someone were to find a game which contained MANY such positions, and only one engine was able to quickly solve all those positions? Then maybe that game should be awarded the prize: "brilliant chess engine game." Why? because the exceptional moves would satisfy the criteria: (1) hard for a chess engine to find, (2) stunning [in the eyes of chess programmers]. Chess programmers are truly a wierd lot. They have a different concept of chess beauty. : ) Bob D.
