Answers.Body: <p>For professional level engines, I run Houdini 1.5 (I imagine newer, paid versions of Houdini work as well) and Stockfish in SCID. The Houdini exe loads fine in SCID so long as wine is installed and the exe has been made executable. Both work very well for me, but I find Houdini's evaluations (e.g. -0.71 is a clear advantage to Black) to be the most meaningful. Stockfish evaluations are often inflated/optimistic (-0.71 might only mean a minuscule advantage to Black or +1.5 might not mean White is winning, but that Black in fact has strong compensation for the exchange. In my opinion, Houdini is particularly good at evaluating compensation for material deficit. I've tried the Toga, Fruit, and Glaurang engines; they are fine and , to my recollection, work well with SCID, but not as strong as Houdini and Stockfish.</p>
  
  <p>For a simple chessmaster equivalent program, pychess (in the Ubuntu software center) might be suitable.</p>

Answers.Text: And NO, Houdini evaluations are NOT more meaningful in any sense than those offered by Stockfish, and this is extremely easy to see by analyzing historical games with both engines. Nope, in any way Houdini analyzes better than Stockfish. That is just Chessbase sponsoring. As you have been doing for more than a decade. Stop that. Enough is enough.

  The UCI protocol (UCI = universal chess interface) only describes the communication

  The Stockfish Linux version won't run on a windows box, just as  the Stockfish Windows
  version won't run on Linux, whereas both support the UCI protocol.
  Some engines - f.e. Stockfish - provide multiple implementations for different operating systems,
  but many engines are for windows only.<br>
  <strong><em>So it's nothing wrong with best engine for Linux, best engine for Windows !</em></strong><br>
  Engines implemented in a cross-platform language as Java ("write once run everywhere") will run on
  several platforms, if Java VM is available for that operating system.</p>

Answers.Text: Unfortunately the most popular/the best chess clients and a lot of other great chess tools are only for windows. Babaschess runs fine with Wine, but Fritz doesn't. So you have no other choice. And VirtualBox is a peace of cake with seamless mode, snapshot feature and shared folder for datatransfer between Windows + Linux. When using Wine you have to install a lot of windows stuff too, it's similar.
