Fritz 18 version 10 (from August 2022):


Since this has been going on for months, I recommend that everyone use version 10 of Fritz 18. Please do not update to version 17.

[Eduard Nemeth]

This has been going on for a few months. I forwarded the BUG to ChessBase, then update 16 came out. After now again long time update 17 comes out, but still totally BUGGY. How often should I write to ChessBase? I have no more desire!

I have seen many losses with this BUG on the server PlayChess, but I can only kibitz or play myself. Many losing games I could not even see.

Here are 4 positions, the first 3 are from version 14 or 16 I don't know exactly. The last position is the one from today, but today alone there were more such defeats:

8/5N2/8/3K2p1/5kP1/3p4/8/8 w - - 0 1
8/2p5/8/1K1k4/8/P6P/8/8 b - - 0 1
8/8/7k/2K5/1p4n1/1P6/P7/8 b - - 0 1
8/8/8/5pp1/4k3/4P1K1/5P2/8 w - - 0 113

I will continue to collect and have the games chipped for myself, but I will not play the eternal beta tester for ChessBase - I am very dissatisfied.
