Thr timeproof only 3 openings


If this is your opening repertoire I would recommend changing the dutch for something else. Both the english and the caro kann are positional in nature (although white has the option of making the game a tactical mess in the Tal variation). While the dutch is most commonly an aggressive attacking opening. However if you would rather go for the dutch stonewall instead of the classical or leningrad, it would make sense to have this as an opening repertoire. Although I would recommend the slav defence if you play the caro kann since they can transpose. You can for example play c6 and d5 against absolutely everything white has to offer.
