I own many programs, but Rebel remains the one that actually runs daily on my computers. 1.0 - Review by a Beta Tester Rebel Tiger 13.0 is a remarkable chess program from Christophe Theron. Tiger 13.0 plays a somewhat quiet style of chess, but the instant you make a tactical mistake, he is all over you. He will even sometimes play bold attacking chess if he senses weakness in your king position. He is very tough to beat as many on the various Internet chess servers have found out.
Tiger plays on the Internet without the aide of other software.
This makes it easy to pit Tiger against other programs or even IMs and GMs on the Net. Many have found that this program is a major force to be reckoned with. Tiger's endgame knowledge is frequently quite impressive. Without tablebases, it correctly and forcefully plays many endings that seem drawn, and he wins. Both Tiger 13.0 and Gambit Tiger 1.0 run under Windows in a Graphical environment.
