### Sting SF 11

The project Sting is to prove that there is possible to join the ELO and IQ abilities and to create some quasi-intelligent Alpha-Beta chess engines.

Sting is "one brain in one head" engine. It means Sting doesn't use some trick parameters: null-move disabling, rule-50 changing etc..

Sting plays and solves in the same way.

The next step of my work is here:

Can someone make a link to the source that is not on mediafire or dropbox?

My internet will not allow me to collect from those places.

Some words about the new version.

Now, you can try to solve each very difficult position (Machines don't cry!

)

But it is not the end of my work. The version 11 is probably the last step before an important gate.

I see a new amazing area. It may take some longer time, for this is the version 11.

Thank you for all of your efforts. Sting is a

Hello Marek!

To celebrate nr.11, one of the masterpieces Sting can master better then all the other engines.

Salai Ladislav Jr. (a little pity is only the Major Dual 1.Bd1, but that's even more difficult to find than 1.f4):

I added 4 new examples to "IQ" test.

The "IQ" test is a very important part of my project and doesn't contain middle-game tactical positions and technical endgames.

Here are only positions dedicated to test so-called by me quasi-intelligent abilities of engines.

Don't use such external tricks like: rule-50 changing, null-move disabling, special parameters and others.

MultiPV, tablebases and "Monte Carlo" are not welcome too.

Time to solve each of items should be 30 minutes for 1 000 000 nodes/second speed. It means 3 minutes for 10 000 000 nodes/second only. Of course, the going on last depth should not be broken.

The DRAW result means ZERO score or a missing gain.

The WIN result means the correct solution mainly and any gain.

Here are rather easy, sometimes specially simplified be me, examples of possible problems for a clessic model of engines.

The spectrum of examples (90 items) and estimated time of solving are not accidental.
