He began playing chess at age 14, and later emigrated to Chicago with his family.1 He is a FIDE Master, and the son of the late National Master Erik Karklins. He is the author of the book "Modern Grandmaster Chess," in which he analyzed every game played in the USSR Zonal (1964), and the editor of "Tal's Masterpieces and Other Selected Games 1960-1975."

He played in Lone Pine (1971), Lone Pine (1972) (finishing =2nd), Lone Pine (1973), Lone Pine (1974) (finishing =4th), and Lone Pine (1975). He competed in the US Championship (1973) (finishing with an even score) and United States Championship (1974). He again was Illinois State Champion in 1990 and co-champion in 1993. In 2009 he shared first place at Ohio's Kings Island Open with GM Benjamin Finegold and two others, ahead of GM Eugene Perelshteyn.
