an interesting new feature of wine 1.2 is it's 64-bit support. Many Windows chess engines gain about 50-80% speed increase when running at 64-bit. Most provide 32-bit and 64-bit engines. But on my 64-bit Ubuntu 10.04 only an error message appears i.e. with the free Stockfish 1.8.

I tested the 64-bit versions of these free chess engines

Hannibal 1.0a: http://sites.google.com/site/edapostol/hannibal

Houdini 1.03a Single core: http://www.cruxis.com/chess/houdini.htm

Stockfish 1.8 for Windows: http://www.stockfishchess.com/download/

Rybka 2.3.2a: http://www.rybkachess.com/free/Rybka232a.zip

in console mode .. but had no success and got same error. 

Any idea what is wrong with my system [Question] Are there some additional settings to apply? And was somebody lucky running a 64-bit windows chess engine with wine 1.2?
