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 Tina Long
