"IQ test" for engines

[lech]

The test 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 a tricks like: multiPV, rule 50, null-move disabling, special parameters and others.
The time to solve each item 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 depth should not be broken.
The draw result means ZERO score or a missing gain.
Here are rather easy, sometimes simplified be me specially, examples of possible problems for a clessic model of engines.
The spectrum of examples (64 items) and estimated time of solving are not accidental.

BTW. The test is dedicated for machines only, and an interpretation of possible results applies to your imagination mainly.

The time to solve each item should be 30 minutes for 1 000 000 nodes/second speed. It means 3 minutes for 10 000 000 nodes/second only.

Why don't we say each position should be solved by searching no more than 2 billion nodes. Or 1.8 billion for purists.

asmFish passes the first test:

Some positions that you could add :

5kN1/3p1q2/5P2/5PP1/2pK4/1p1R4/1P6/8 w - - bm Rxb3;
8/8/5k2/8/2B4p/5RbP/5pP1/7K b - -; c0 "eval = draw";
3k4/4pp2/n2n4/5BN1/3N4/b7/4K3/8 w - - bm Nxf7+;
2b1rk2/5p2/p1P5/2p2P2/2p5/7B/P7/2KR4 w - - bm f6; (winning)
2r5/prkpR1p1/2p1ppK1/P1p1N1B1/P1P1P3/8/8/8 w - - bm Bf4;
4kr2/5p1K/3p1Q2/1p4P1/4P3/1PP5/7b/8 w - - bm Kh6; c1 "diff=9"; (winning)
n1QBq1k1/5p1p/5KP1/p7/8/8/8/8 w - - bm Bc7; (mate)

The last two positions I think is already included by Marek.

Position 6 is also at Marek's epd at position 57
4kr2/5p1K/3p1Q2/1p4P1/4P3/1PP5/7b/8 w - - bm Kh6; c1 "diff=9"; (winning)

Last position is at Marek's position 59
n1QBq1k1/5p1p/5KP1/p7/8/8/8/8 w - - bm Bc7; (mate)

Some positions are quite interesting, although very tough for engines,
but amusing for humans if analysed OTB.

Position 6 is in Marek's epd position 57 >> is right
Last position is at Marek's position 59 >> is WRONG

n1QBq1k1/5p1p/5KP1/p7/8/8/8/8 w - - bm Bc7; (mate) is NEW

Yes, well seen !

This one is 1 move later. Hard for regular SF

One more :
8/8/8/5Bp1/7k/4p3/5PKP/8 b - - 0 1 - drawish but SF thinks 1...e2 is winning (refuted with 2.Bg4!).

One more :
[d]8/8/8/5Bp1/7k/4p3/5PKP/8 b - - 0 1
drawish but SF thinks 1...e2 is winning (refuted with 2.Bg4!).

I noticed a sub-variation of this position is also interesting as engines are having difficulty to avoid the move e1Q on below position,

[d]8/8/8/5Bp1/7k/7P/4pPK1/8 b - - am e1Q;
Black to Play, Avoid Move e1Q (best is g4 first to un-trap the black K)

Engines don't want to play the clearance sacrifice g4! first.
Most engines just rush with e1Q? quickly and just results to a
fortress draw after Bg4.
