Using new search algorithms this version is estimated 80 points stronger than the 2004 version. With Chess Tiger another jump forward is made, this version has a totally new search algorithm that makes the program 4 to 8 times faster at long time controls. This is where most of the strength improvement came from.
Main Features:
- pins by bishops (there was a bug in CT2004: it would actually AVOID making pins!)
- pawn majorities 2 vs 1 and how to block them when it is possible.
- more passed pawn knowledge.
