I changed: 15, 71 are more difficult, in 4, 20, 39, 49 some obvious first moves are skipped. [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/PpP2p2/1PqP1P2/8/1P6/8 w - - 0...

The hashtable is not common for two (not one) engines and it can sometimes make a difference. It is possible to make an auto-play(ing) manually. Start a search(ing), stop it, skip one move (it is possible to skip more moves too) and start search(ing) again (don't clear the hash table!), stop it, ski...

The "IQ" test doesn't contain middle-game tactical positions and technical endgames. Here are positions dedicated to test so-called by me "quasi-intelligent" abilities of engines. Don't use such tricks like: rule-50 changing, null-move disabling, backward-forward, special parameters (versions) and ...

I decided to remove two examples of this test. Why? At first, in both there is possibility to make solutions much longer. [d]B7/p1p5/k2p4/p3p3/P1Nb1p2/6p1/7p/4K3 w - - {Ke1->c8} 34 - white King can starts from e.g. the a3 square. [d]3k4/8/7p/2p1p1pP/1pPpPpP1/1P1P1P2/N7/2K5 w - - {Na2->h4} 81 - white...

Okay, good (because auto-play probably counts as a "trick" too). You are wrong. If you start the auto-play(ing), you don't change anything. It is only the other way (alternative) to get a solution, especially if it is very long and a "horizon effect" appears, and search(ing) is not able to do it. S...

When I make Sting play white 2 sec move against another engine in this position it always end in draw by 3 fold repetition adjudication.

Try more time per each move.

The main goal of my work is to prove that a chess (alpha-beta) engine is able, without some dirty tricks or external tools or selective code or artifical intelligence, to solve all positions from the above-mentioned "IQ" test. I believe that it is possible to do (implement) it without any ELO loss ...

But it is not the end of the "Black Hole" idea. The first problem: One of many decisions is wrong but has huge advantage (described above). The second problem: One of many decision is good but a success is far or out of range. It needs an "intuition" and Sting 25 has it. To prove it, I selected: nat...

At first, time usded by Sting it is a reason of my very old and slow computer mainly. I never use a special commands to run searching of Sting (no cheating!). I like that other engines (CFish, Crystal ...) try to make engines "normal" too. I hope that not only Sting is able to solve 100/100 position...
