Mastering mating patterns is the next step to getting better at tactics and becoming a dangerous attacker.
It often bridges the gap between a strong attack against the opponent's King and victory.
So once you become better at sniffing checkmates, your attacking skills naturally improve.
Instead of just solving random puzzles and hoping for the pattern to stick, here you’ll train your vision for each mating pattern with deliberate practice!
