...a face-to-face human instructor, regardless of his or her ability, can’t take the place of excellent software. The software is faster. It’s more organized. It generally has larger databases to draw upon. It doesn’t make trivial mistakes based on oversight or forgetting. It’s tireless, and never shows up late, inebriated, or with the flu. It’s willing to help you at any time of day or night. It doesn’t mind doing the same things over and over, till you get it right or for your satisfaction. Its feelings are never hurt no matter what you say or how badly you act. You don’t have to pay for it again and again. You buy it and you own it. There are no human instructors like that.
But again, I say it all boils down on the capacity and ability of an individual to not only properly operate a computer chess softwares manually, but on how skillful and well versed he or she is on the programs to make the most out of these chess software. Now how about start introducing chess software instructors?
