Essential Checkmate Patterns
This module contains 130 challenges that cover all common checkmates and most uncommon checkmates that occur regularly in middlegame positions and sometimes in openings. Nearly all of the positions come from actual games, and the various themes are repeated from simple to more complex examples. This module is suitable for novice players up to intermediate players with Elo or USCF ratings up to 1600, and will enable them to recognize checkmate possibilities in their own games.
