Summary of Changes

Testing and Playing Strength

Conditions: Dual AMD 1.7 GHz w/ 512MB RAM; 4' + 2"; 64MB main hash for Horizon and opponents; 4 MB pawn hash; egtb size 2 MB; ponder off.

Rationale: Opponents are chosen on the basis of well-established Elo ratings and reasonable results against Horizon -- this means staying within a 35% to 65% win percentage. Opposing engines remain in the mix until they fall out of the 35% to 65% range or if there are hangups/crashes.
