10 interference motifs rated between 1800 and 1999, averaging 1891. Each position below is from a real game, with the solution given underneath — so you can check yourself immediately rather than guessing whether you were right.
Interference cuts the line between a defender and what it defends by putting a piece in the way, often a piece that can simply be captured. It is one of the rarest motifs in practical play and one of the most satisfying to find.
These are pitched at 1800-rated players. Puzzle ratings work like player ratings: a puzzle rated 1800 is one that players around 1800 solve about half the time, so if you are getting most of these you should move up a band.
Solving from a page is good for pattern recognition but not for tracking progress. The rated puzzle trainer serves puzzles matched to your own rating and adjusts as you solve, and the Mistake Trainer builds puzzles from positions you actually got wrong in your own games.
