Re: The "IQ" test - update
Crystal3.1 is not bad on this set. Conditions : 10 min (1 core old i7@4 GHz) per position 79 found but I have to check manually a dozen of solutions to see if it really solves them. A good work Vincent! The task is: to solve all 100/100 positions (half hour per item for 4 000 000 nodes/sec) . It is...

Re: Sting SF 27
"A new day with a new Sting is a good day." Hi lech, This problem is too old but when I set Sting's thread as 3 it starts analyzing with 4. Can you check this problem? Also, I really wonder how strong will be Sting if you add your path into last Stockfish's sources. I think that engines to control ...

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.

Re: Sting SF 25
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...

Re: The "IQ" test - update
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 ...

Re: The "IQ" test - update
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...

Re: Sting SF 25
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...
