STS - Important problem with scoring of STS2

[Robert Houdart]

There is a major problem with the scoring of STS2 by STSStat which is apparent when you look at the results.

For example:


For STS2 the best move is found 88/100, but this gets a Score/1000 of only 861 (less than 10 times the "best move found" count). For all other STS the "Score/1000" is always higher than 10 times the best move hit.

The problem comes from typos in the STS2.epd file which make STSStat work incorrectly for at least 9 positions.
For positions 31, 41, 55, 62, 78 the "c0" comment contains a full move instead of a short move (e.g. "Bb7c8=10" instead of "Bc8=10").
For positions 32, 45, 93 the "c0" comment comes after the "id" text, and the comment starts with a space.
For position 28 the best move Bf8 only gets 8 points, whereas Rc2 gets 10 points.

Hope this helps,
Robert

Thanks, I'll forward this to Dann.

Hopefully we will come up with new update.

We have updated the STS2 file with some new positions and bug fixes.
