@triso because some of the engines, notably the two strongest, are not offered as native linux programs. i've updated my ubuntu 64-bit wine install script to use wine 1.3.13 http://www.jesseo.com/chess/64-bit-wine-ubuntu-1.3.13.sh i've gotten many engines to run from the terminal with this command "/home/USERNAME/wine64/wine" cmd.exe /K DeepRybka4x64.exe
