Ruy Lopez-For the positional player this is an excellent choice, as this opening demands a good strategic understanding.
French Defense-Typically leads to closed strategic positions, and is very solid. Botvinnik and Nimzovich were playing great French defense.
Slav defense-Solid, not quite as dynamic as the Semi-Slav but still giving Black reasonable play. Pawn structure is similar to that of the Caro-Kann.
Grunfeld-This is a good opening that many players of the White pieces feel uncomfortable playing against.
