In-between moves is lesson 1 of 8 in Quiet moves, a tactics course suited to players rated around 1400 (club players). Before you recapture by reflex, look for a stronger move in between (the German zwischenzug): a check or a threat first, the recapture later. It has 5 interactive exercises: 5 calculated lines from real positions. You play every move on a board and get feedback straight away. The lesson is free.
