Re: Sting SF 21

The "IQ" test is a very important part of my project (Sting) and doesn't contain middle-game tactical positions and technical endgames. Here are positions dedicated to all engines to test so-called by me "quasi-intelligent" their abilities. Don't use such external tricks like: rule-50 changing, null...

Sting SF 21

My project sting is dedicated to solve difficult studies, and not middle-game tactical positions.

There are a few important modifications.
Also I added an old code ("lazy King") tried by me earlier.

Latest Crystal solves about 65/100 in one minute limit and 4 cores. With "solving" I mean first move or win/draw.
if so, it seems to be a succes of the project Sting too. :)

Re: Sting SF 20

Many studies have too long solution for searching. Example: Neghina's study (win) [FEN "7q/b1p5/1p1Npkb1/pPP2ppP/P1P5/3B2P1/5P1R/K3R3 w - - 0 1"] 1. hxg6 Qxh2 2. Rxe6 Kxe6 3. g7 Qh1 4. Kb2 Qa8 5. Bxf5 Kf6 6. Nc8 Kxg7 7. c6 Kf6 If an engine returns 7. c6 (searching) move it is only one way to get the...

Re: Sting SF 20

How many of these 100 positions Sting solves in reasonable time limit 1/5/10 minutes? + what are the improvements since version 19 on this set ? The "iq" test contains examples of many groups of problems which need a special code. Without the code alpha-beta engines (probably NN too) are not able o...

And the transformation into a rook is necessary (2.b8R or 4.b8R)
All is ok. The move 1.Kc5 instead of 1.b7 makes the solution only a bit longer without any sense.

Re: Position : Win or Draw ?

Many of you can't understand that searching doesn't return the result (excluding mate score).
If you want to know the result try "auto-playing" or playing. :)
