Rybka 2, the world’s strongest chess program, leads all ranking lists clearly, with ratings well above Elo 3000. Now Rybka 3 is here, with a dramatic improvement of at least 80 Elo points.

Monte Carlo Analysis yields precise evaluations by playing thousands of ultra-fast games in a few minutes in a given position.

Endgames – engines often give high scores to drawn endgames (and sometimes low scores to winning ones). Monte Carlo recognises fortresses and other no-progress situations. It's also good in rook endgames, which are another computer problem.
Positions where one side has made a big material sacrifice for slow compensation (i.e. not just tactics). For instance you can find lots of piece sacrifices in famous grandmaster chess games which no computer will correctly appreciate and which Monte Carlo gets right.
