A chain is related to a station cascade
, and refers to the case where a sequence of stations are played without a full cascade being in effect. The most obvious example of a chain is when a series of stations all on the same line are played. A more tactical variation is to play a series of stations where each has a subtler connection to the previous station, such as the following sequence extracted from Tibor Hugo's
1925 victory against Sydney Hall
: Royal Oak - Kensal Green - Nightingale Lane - Neasden and Kingsbury. Hugo's play of Kingsbury blocked Hall for over fifteen minutes and it was the time shortages he suffered later on in the game that led to his two unforced errors and ultimately handed victory to Hugo.
