Rev 2 underpromotion query

Post by Shaun »

Hi All

Does anyone have problems under promoting when using Rev 2? In a tricky puzzle, Rev 2 needed to promote to a Knight. The machine recognised this crucial move straightaway - the entire line starting 'd8 N ...' was found and displayed in a moment (even on the default level) - very impressive - but it was impossible to reproduce this promotion on the board.

Best Wishes All

Morning Al

I'm running Hiarcs on version 3.14. I haven't upgraded as I don't really understand the process. Comments welcome!

Any further news from Square Off, btw?

Hi Shaun,

You are quite correct, you have found a bug. When you replace the pawn with the knight, 2 corners flash and the piece is not recognised.

I tried this again on Stockfish 6 and it works perfectly, then I realised you don’t have this Engine, so I tried again with Baron 1.0, again it works fine.

I haven’t tried all Engines, but under promotion to a Knight does not complete on Hiarcs 14.1.


Cheers,

Al.
