The suite consists of 30 positions choices all with a feature: undertake the program, but it are not impossible to solve.
SK 6 manages to resolve all it with a time your hardware dependent.
This test set can serve to compare the various versions of SK, but also to set the best hash memory and the various parameters of the program according to your hardware.

Here's an example of the results on my old dual core:
STOK 6 x64: Max time = 150s (no tablebase).
result: 23 on 30 = 76.6%. Average time:= 27.14s / 24.39
STOK 5 x 64: Max time = 150s (no tablebase).
result: 21 on 30 = 70.0%. Average time:= 35.09s / 25.00
Some positions are of the old test "Marathon". Some positions were taken from my endgame test set: "Hardends2013" and comes from the books of Dvoretsky. other positions are real games, others are studies or modifications of known positions.
Were chosen because:
- Undertake SK but are not impossible to solve.
- Some are resolved by SK6 while earlier versions not resolved or took a much longer time.
- Some positions are "unstable" for SK. Sometimes resolves in short time, sometimes in a very long time.
I tried to cover the whole range of classical themes of chess problems, that I can not list here for the language barrier.
