Advanced Mornington Cresent was the second major version of the game.
Concieved to address concerns that the original was too simple, and lacked skill and subtly, this version added a lot of the self-explanatory features we now use in standard play today;
Latorals, Transits, NorthenLine exceptions and Queensgate bridge moves.
As well as some of the more obscure rules, such as Quadjumps, Spagholeing and Reverse Bi-Polar Bunny Spotting.
The International Mornington Crescent Society no longer supports these rules, but as yet no penulties have been attached to using them. As long as no new version of the rules directly contradicts these rules they are applicable. With the exception of Spagholeing, which has a ten year ban accross all versions.
