I added 3 new items. The last is very interesting.

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 (93 items) and estimated time of solving are not accidental.
