True. >I have a question about the other Rebel 10 settings. When Selection is set to >normal what does that mean? Does it assess the position and choose a >selection accordingly ? Or does it pick one selection setting and stick with it >throughout the game? I quote the manual: 4.3.6. Selection (menu Option ) The program (when brute force is off) has its own intelligent flexible algorithm to decide if a given variation should be extended or not. This is called "selection" and is based on a judgement by the program whether it makes sense to extend a given variation or not. With this option you can turn off the program algorithm and change it into a fixed depth of selection. You will have the choice between 1 through 9. "N" is the default setting meaning Normal. If you were to choose selective 4, while the program was, for example, on the 9th ply, this would mean that the calculations were done with the settings: 5 ply brute force and 4 ply selective thereafter. With Normal the whole selection scheme is totally flexible. [ end of quote ] >Ditto for Play Style options. Do those vary throughout the course of a game >when "Normal" is chosen - sometimes solid or sometimes agressive? Or does normal > mean just this one setting? In the case of "playing style": once chosen it will stick to the setting and plays accordingly until you change it. The "playing style" options mainly refer to Rebel's mobility chess knowledge. That means: - Aggressive (very strong emphasis on mobility) - Active (strong emphasis on mobility) - Normal (default mobility) - Solid (low emphasis on mobility) - Defensive (very low emphasis on mobility) >>At the moment we investigate if there is a (very) quick way to include >>Chess Tiger in Rebel10 as an engine (same approach as loading older Rebel >>engines). >Any idea of the cost to purchase the Tiger add-on if made available? I haven't the slightest idea. The thought didn't crossed my mind sofar. First results of Chess Tiger: CT - H6 4.0 - 5.0 CT - N98 6.5 - 6.5 CT - S2 7.5 - 4.5 S2 - CT 5.0 - 3.0 Already impressive since Tiger hardly has an opening book and a learning algorithm. - Ed -
