Forks, pins, skewers, as well as discovered checks, double checks, zwischenzug and deflection. These are all tactics that are often seen in chess. But a rarely-seen tactic is interference. This is when a piece is sacrificially interposed so that an opposing piece is left isolated and vulnerable to capture.
An excellent example occurred on Tuesday this week, when David Green (White) faced Stephen Lewis in the second round of the Stowmarket Club Championship. This was the critical position after 27 moves of a Budapest Defence:
Here, David found the remarkable 28. Be5! It won him the exchange, but not the game, which petered out to a draw. David has another opportunity to prove that he’s a good chess player as well as an excellent Competitions Secretary when he plays for Suffolk Under 160s on Sunday.
