"Powerful engine, worth the money than fritz and chessmaster."
Can take advantage of your dual core and up to 4 dual core cpus. That means more difficult moves to find with less time to think. It has full time controls and you can limit it's strength. It's stronger than my old fritz 9 and chessmaster can't even analyze the unique and aggressive move of Deep Sjeng. You can even change the personality from aggressive to defensive or passive. You can use the engine with other gui chessboards like arena.
You can't resize the chessboard. Nalimov 5 piece endgame tablebases aren't included (you have to download the 7.5 gigs file in the internet). Opening book aren't as deep as Fritz or Chessmaster. After 10 moves, it will start to think unlike fritz which will start to think after more than 16 moves.
