A short contribution by Tim Krabbe
My favorite computer move.
Every chess player has at times been impressed by 'typical computer moves'; moves that seem crazy at first sight and that a human would never think of, but that are tactically brilliant.
A while ago however, analyzing with Rebel for my Website story 'Alekhine's 5-queen game', something so strange happened that I thought my computer had gone berserk, or that I had discovered a very nasty bug in Rebel.
Black to move
Even when Black is in check, and therefore had a limited choice, the move that Rebel immediately plays here, 28...Bd6, would never occur to a human. It seems totally improbable: a selfpin that also allows a fork of the own Queen. But when you look closer, you begin to see its merits.
After 29.Rxd6+ Kc7, the Rd6 is simply en prise, and Black remains a pawn up in all variations, e.g.: 30.Rxd1+ Nxf4+
29.Bxe2 doesn't help either: 29...Qd5+ 30.Bf3 Kc7! (another typical computer move) 31.Rh7+ Kb8 and Black is better.
And also after 29.Qxd6+ Qxd6 30.Rxd6+ Kc5, Black remains a pawn up. It's really a pity that after a minute or two, Rebel refutes its own fantastic move with 29.Qb4+ Kc7 30.Qc4+ Kb6 (Kb8 31.Bxe2 and White wins) 31.Nxe2 and White has a very strong attack.
Seeing that, it plays the simple 28...Ka5! 29.Bxe2 Qd4, after which Black is also a pawn up, and has nothing to fear.
If only that Black pawn were at a5 instead of at a7...
