I thought Adobe and Microsoft were bad, but Feral Interactive has just released a patch for Chessmaster 9000 that brings Universal Binary status to the well known chess application. Other changes in version 1.1.2 include support for the latest MacBooks with Intel X3100 graphics. So now you can finally try the Queen's gambit on your Intel Mac without the distaste of Rosetta.
The 1.1.2 Universal patch is a free download from Feral. Chessmaster 9000 retails for about $40.
