Goodge Street opened on 22nd June 1907 as Tottenham Court Road, renamed on 9th March 1908. On the same day Oxford Street station was renamed Tottenham Court Road. This gives rise to an interesting convention, which can rescue a seemly lost game. If an opponent plays Goodge Street, which can often be a penultimate move to Mornington Crescent, one can play Tottenham Court Road and invoke pre-1908 rules. This has the effect of relocating both stations and thus both players. Your opponent is now blocked northbound on the Northern Line and thus direct access to Mornington Crescent is cut-off; whereas you are placed in a very advantageous position.
