As a side note, last night at FICS "PPC" (Hiarcs 6, 250MHz G3 PowerMac,
manually operated) scored 60%+ against "Perplexity" (200 MHz Pentium,
32MB, automated Crafty 14.4, big book, all TBs [4 men + KRx-KR]) in 0 4
lightning.

2 games were drawn (1x repetition in early opening, 1x insufficient
material). PPC was mated only once, lost/resigned 3 or 4 on time and won
the rest (6 or 7). PPC gained 400+ rating points, Perplexity lost 90 or
so.
