    Case of Mofongo is easy: see it's formula. It does not play computers.... My
experience shows that if you exclude computers from opponent pool your rating
goes some +100-200 points higher... Comparing ratings on icc seem to make sense
only when both handles have same formulas... Now see other crafty clones without
formula restrictions...
  Examples are Tryagain (K2-300Mhz; 2656)  Razzle(K2-400mhz; 2636),
KillerGrob(PII 450; 2818)....and, for comparison, say junior (Ban): PII-333;
2930 (also without restricting formula)...
