Only all your new work is nothing more that making it accessible everywhere and for everyone. I do expect that some graphics interface (between those that are free and compatible) will be present already with your engin on its original Web Site. Beside this, inclusion of engin inside of all major chess programs will go its own way. It still will take few years before engin will be everywhere. For me it should become as omnipresent, as now became Crafty in all big chess packages. It could be that this will spur somehow general interest for mate problems that is now on much lower level that I expected. >>>>I hope that now Windows will become something of half way between previous >>>>Windows and actual Linux.

Sometime too much greed is deadly fault. For sure you remember COCO (or name that sound this way) produced by Radio Shack and that was very popular up to 1988. Company killed its product by trying to keep everything in its hands. The other company that is in agony but still alive is famous Apple. Sad story that repeat itself!
