As usual, I enjoy some things in human chess, too, and after ...Nf3+, whites
defences look a bit awkward. I'm nowhere near any chess computer program now,
nor do I recall the position. And the quiet move might be to do with moving the
night out. HONESTLY, after PxN and BxP, how can White manuever a defence before
Black comes down with his queen? Oh! so if you are saying it's extremely easy
for any human reading this forum, I appologise. Maybe it IS (although it doesn't
seem so from some of the comments on this [Why does it need to be a classic
Alekhine combination?]), but for a computers way of thinking, it used to be
impossible, but today, it's rather much easier. It's not deep enough however to
be a great challenge to a computer. Direct mating threats are not all that deep
into the position from that diagramed.
