Luv Macs. It's a feel thing. Not rational. Unless honoring your feelings is a rational way to proceed. My Mac has a program called "Chess," which is different from "MacChess," apparently. It's not great. It makes great big blunders, even right of center on the slider - as in, stronger play. You guys are out of my league, technology-wise. I'm just relieved I can beat the thing, right of center. Sorry if I've contributed nothing; I'm trying to understand the mechanics of this posting tool. Learning by doing. Peace.
