Nor can DJ. Didn't you correctly point out that the tactical error that cost it
the game against DF was done at a VERY low speed of 53 kN/sec.?  I'd still like
someone such as Amir or Enrique to tell me that this was normal and not due to
some unforseen technical problem (such as the auto232 player).
