Look at Fritz some time. I just saw this in this forum:

New game,

Fritz gets deeper and deeper (cough) and the PV gets longer. But what happens
now, just when it is becoming really interesting, what a dissapointment ...

Shall I run to the patent office immediately with my new product PViagra -
principal variations long and strong!

Cheers,
