|Chess Kit » Training » Tactics » Interference
Fred, " Interference, as the term indicates, occurs where the defender forced
to block himself. He has a choice of moving two pieces to a critical square.
Whichever piece he moves, he blocks the operations of the other piece and is
thus left helpless against his opponent's threats. In general, the interference
theme produces a large proportion of artistic conclusions. This is due to the
finesse involved in forcing the defender's pieces to destroy each others working
ability". Back to Tactics page
