Sting SF 11

[lech]

For me, Sting SF 11 is first intelligent chess engine.
I think that no honest chess engine is able to solve the "IQ" test now and in the next 100 years. No Alpha-Zero engine is able to change it.

That should be Klyatskin Mikhail, cf. CN 646.

I tried Sting 11 with Kornrade test:
http://talkchess.com/forum3/viewtopic.p ... ng#p773630

Sting can have a serious problem only with:
14 Fork-field +- [FEN "3B2r1/n3Pp2/P7/5k1p/q3NP2/7K/5P2/4NB2 w - - 0 1"]
It is my mistake and version 11.1 will be soon.

There is a question to:
11 Chase +- [FEN "4N2k/4PB1p/7P/B1p5/2P5/3q2Pp/1P3P1K/2r5 w - - 0 1"]
Probably I am too restrictive for such examples.

[lech]

Thanks to the Kornrade test (4, 11, 14) I found a few my mistakes.
New version Sting SF 11.2 is here:

I wonder if someone can post the sting source in a location I can access like google drive or some other source.
