Two weeks ago we looked at a spectacular victory by Mamedyarov at the National championship of Azerbaijan. The pre-tournament favorite eventually managed to reach the final but was surprisingly defeated by GM Muradli. It seemed as if both players surprised each other with the Open Catalan (5...Bd7) and in a well-known theoretical position Mamedyarov committed the decisive blunder already on move 12. This variation used to be quite popular 10-15 years ago, but isn't seen often any longer. In this episode I'll offer an overview of the theoretical possibilities for both sides.
