Aahh, now that IS interesting.
I can dismiss my ponderings about which selectivity to use in the middle vs the
end-game, as the selectivity automatically decreases as the endgame approaches.

(Also indicates I was correct in thinking less selectivity in the endgame is
better).

I'd noticed this selectivity "wrongness" before but hadn't rationalised.

It is very pleasing to see some of the methods & strategies employed by chess
programmers.

I've always acknowledged that chess programmers are, in some aspects of the
brain,  veeerrryyy intelligent.

Thanks for the insight John,

See Ya guys
