4.3.13 Combination

If Combination=ON (the default setting) the program generally will find the right moves in tactical positions faster than when combination is off due to a special tactical search. Combination=ON will find key-moves up to 10 times faster. The Combination=ON setting is also meant for popular computer test-sets. With Combination=ON Rebel will score better in these test-sets.

Note
In opposite to earlier Rebel releases, this option, if set to ON, is now also active for whole games and only for positions.
