I have not a dual processor computer; muy very best one is a decent but not top-notch Armada with around 100Mg in Ram and 266 Mhz. My question is: what can I get from Junior 6 with this machine? It will be apreciable stronger -let us say, 50 to 75 elo points- than my actual J. 4,6? And what is more, will give me more chances to improve my game with features adequate to that task? I mean, aditional features to what Chessbase products actually gives? Or said in another word: I will be beaten just because superior tactical ability as any top proam an do or I will see a positional lesson, a lesson also in endings -if I get there-, a lesson in everuthings hat counts? Or just I am asking too much? :-) Fernando the sadomasochist...
