THE ROCK SOLID OPENING REPERTOIRE challenge

Take part in the daily chess tournament and practice the middlegame positions from the ROCK SOLID OPENING REPERTOIRE!
Join here: https://www.chess.com/tournament/rock-solid-opening-repertoire-challenge 

The starting position is the Catalan Opening from White's perspective and the Tartakower Defense from Black's perspective. It appears after 11 moves if both White and Black follow the rock-solid opening repertoire. You are going to play 2 games against each opponent - one with White and one with Black. 

For even better results, I recommend downloading the complete ROCK SOLID OPENING REPERTOIRE: https://rocksolid.matbobula.com/
