As a former college chess champ, I won't insult you with the usual suggestions but probably intensive tactics practice will most quickly help you regain your board vision. Try wandering around Coach Heisman's site and see if anything resonates. He has 10 years worth of archived "Novice Nook" columns (not really for novices at all ) that have won all kinds of chess journalism awards. Enjoy!
