What do you mean by advanced technology ?
About engine like leela ?

Sorry, but I am far to joke.

Indeed this example proves that an Alpha-Beta engine is able, without any tricks, to make that impossible.
A pity that my project (brain) is killing by an advanced technology.

A pity, that Sting SF 21 loses its games on time !

I found here: https://chessengines.blogspot.com/2020/ ... e-uci.html
a rating of Sting SF 21. Where is a problem?

Indeed it seems to be much better to save the first item of the "IQ" test in an original way as study. Thanks! [Result "1"] [FEN "rkr5/p5p1/Pp4Kp/8/3B4/1B6/8/8 w - - 0 1"] 1. Be5 {win} [Result "2"] [FEN "7k/6rp/6pN/1r4P1/3B4/8/8/K7 b - - 0 1"] 1... Rxg5 [Result "3"] [FEN "1B1k4/3p4/1Kp5/PpP2p2/1PqP1...

If it is so important and I remember good, I am the autor of items: 2, 4, 40, 41, 100 only and I am still alive.

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...

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.

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...

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...
