A poster on Chessgod101 has a link to an old collection of Chess Tiger engines that includes Chess Tiger 15 (ChessBase version) and Chess Tiger 2007 UCI.
For those that are unfamiliar with Chess Tiger it was a strong engine developed by Christophe Théron which achieved a number of tournament successes 10-12 years ago. Although still commercially available, the Windows version has not been developed recently. It was strong but still inferior to Fritz, Houdini and Shredder. Most engines tend to avoid gambits and sacrifices but Chess Tiger actually prefers them. This makes it a good engine to practice against if you want more “human-like” play. It calculates very quickly. On the CCLR 40/40 rating list Chess Tiger 2007 is ranked #62.
