It's all about la diffèrence... How about rook endings?
Decided to match a commercial top engine vs a free rising star.
Fritz 7 - Aristarch 40 moves in 60 minutes from the position below.
PIII 800 64 Mb each.
[D]8/1ppr1kp1/p1p4p/8/8/5P2/PPP1RKPP/8 w - - 0 1
This position looks like sprung from the Lopez Exchange variation.
A possible pawn ending is won for white. So this is the first thing
black must avoid.
Game 1: Fritz-Aristarch 1-0 - black comitted the greatest of sins
and lost the pawn ending quickly.
Game 2: Aristarch-Fritz 0-1 - white just drifted into a worse position
and lost himself in the darkness.
