GAMBIT TIGER... breaking news

TWO versions of Chess Tiger will be available on the REBEL 11.0 cdrom:

• The traditional Classic Tiger which is estimated 50-70 elo points stronger than its precursor.



• A Gambit version of Tiger which plays a whole different game of Chess using a new king safety concept. Gambit Tiger is able to play all kind of gambits much better than the Classic Tiger. Gambit Tiger will be offered as a separate engine which you can load under Options -> Engine.

The Gambit Tiger is estimated in the range of +/- 20 elo points in comparison with the Classic Tiger. Gambit Tiger is not claimed to be much stronger than the Classic Tiger as too less data is available at this moment.

What is clear is that Gambit Tiger plays an aggressive type of Chess seldom seen by a chess program. Below is one of the very first blitz games Gambit Tiger played.
