  thegoodanarchist: Wow, a stunning destruction of Deep Blue by a mere 2400 player. Unexpected, to say the least.

Just 5 years later the contraption would go on to defeat Kasparov.

Jan-08-17  izimbra: This is a strange anti-engine game because a modern engine sees instantly that both <9.Nb5> and <10.Nxc7> actually loses material for White. Deep Blue killed itself here, missing only modestly deep tactics. Perhaps it was a software bug or perhaps a horizon effect, where the engine doesn't see that after Nxa8 the N is either going to be recaptured or require some special rescue effort. For example: <9.Nb5 Bxe3 10.fxe3 Qxe4 11.Nxc7 Qxc4 12.Nxa8 Qc5 13.Re1 Qe5> The Na8 is walking dead, so W is down material, B+N for a R. Deep Blue was supposed to be able to see deeper than that, so it's not clear what went wrong. But I guess that W has some fake tactics to delay the inevitable recapture of the deceased horsie beyond its depth horizon, essentially fooling itself about the material imbalance of the position.

  WorstPlayerEver: Tactical abilities of engines are overrated. In fact it's a bit of a hoax.
