I was never able to find any use for a big hash table, nothing bigger than 128MB helped, and sometimes clearing the hash found the move faster in a key position (on the distance, not at the root.) I guess if you're at the point at which a bigger hash helps the position, it's also the point you're sitting way too much time on the same one.

(!) I replaced the last item by a missing "perpetual check" example.

The "IQ" test is a very important part of my project (Sting) and doesn't contain middle-game tactical positions and technical endgames.
Here are positions dedicated to all engines to test so-called by me "quasi-intelligent" theirs abilities.
Set parameters: "threads" to 1 and "hash" to 1024 and clear hash before each of items.
Don't use such external tricks like: rule-50 changing, null-move disabling, special parameters and others.
The external tools like: MultiPV, tablebases, "backward-forward" and "Monte Carlo" are not welcome too.

"WIN" means the correct solution and some non-zero plus score.
Don't do the test in a machine way. Test and analyze each of items separately!

Thanks, it is my mistake and I found 2 nexts. The corrected version is:

Position 35 is part of the study Detour (2010), which has been discussed here in some topics over the years:
White to move and win.

Have fun!

Probably here ("IQ" test) are many positions based on studies. The position 35 rather doesn't happen in the solution of your study (King on a1).
The version of "IQ" test seems to be the last and is open (forum) for commentaries. :)

And the transformation into a rook is necessary (2.b8R or 4.b8R)

All is ok. The move 1.Kc5 instead of 1.b7 makes the solution only a bit longer without any sense.
