The inevitable return of Mornington Crescent

[ComeIntoTheGardenMaud]

As winter approaches and the nights draw in, one’s thoughts naturally turn to wholesome, homely entertainment. Instead, though, I invite experienced players and novices alike to join me in a game of Mornington Crescent.

To keep the pace gentle, I’ll begin with an inverse Lepton to

Seven Sisters

Which leads us inexorably to

Piccadilly Circus

I didn't see that coming. I'm consulting the Heimar adjustment (2001) and can see it's allowed. Therefore:

Colindale

Picadilly Circus again? Within fewer than 10 moves? Breach of both Bakerloo Declarations, surely?

Who adjudicates when the chair is also a player?

The Bakerloo declarations are void during partial or total solar eclipses, @FatOaf , at least in professional play. Although, to be fair, a quick thumb through the Almanac reveals that the participants in the semifinals of the last seven years seemed to have overlooked this. Nonetheless, let us stick to the rules. I think there's a scalene opposition in the makings, so I'll try and head us that way with Marylebone.

Novice here but I'm pretty sure the next move would be
Maida Vale

Oh, pardon me. I was going to blame a combination of amnesia, the loss of my second-best pince-nez and an unusually generous pre-prandial sherry, but GirlInTheDryShirt has pointed out that the partial eclipse lets me off the hook. Phew.

As I feel emboldened

London City Airport

I presume this means the fourtmya rules are now void? If I'm correct then this discounts the backwards shift I was going to play.

Bit of a head scratcher but I'm off to

Golders Green

Such verve!

City Thameslink

Oh lovely. That frees me up to do a south shuffle to East Putney.

Dagenham Heathway

(due to the accessibility issues at adjacent stations obvs)

Based on Timkins's Accessibility and Interchange protocol 2nd Ed. I am going for
Canning Town

That’s all very well, but we can’t postpone any longer the mandatory triple jetée to

South Kenton

Dalston junction

I had to switch to step-free mode

Ooh, we're on my old stomping ground now.

Stamford Hill

Whence we may essay a transectional loop to

Perivale

May I insert a wild card at this juncture?
Croxley
(I think 1987 Metropolitan sanctions apply here)

Oh. That invalidates my wild card you absolute rotter.

I am now only permitted to move to Goldhawk Road

I had to step away to attend to other matters, but I see that in my absence all hell has broken loose. A triple jetee together with the invocation of the 1987 Metropolitan sanctions, on the fourth Tuesday of the month at that? Because we're still within 30 days of Michaelmas, I think one or the other might be allowed, but surely not both, so I'm not sure that @HazelBite's wildcard is altogether permissible, although I'll defer to the chair. Either way, I think that a swift play of an Overground station might return some order to this evening's proceedings, so I'll chance a move to Wanstead Park.

Here, as in so many areas of life, I feel we should defer to the late Queen Mother and her maxim of “never complain, never explain”. (She, of course, was a skilful proponent of the game of games). GirlInTheDryShirt has got us back on track (pun very much intended) and I shall advance to

Beckenham Junction.

Ohhhhh Purley

Sorry, a bit obvious, I know. I had a difficult night pondering the Von Westinghaus problem. But I think I've got there.

I've had the valet bring me the rule book from our summer house so that I could check the legality of this move. According to Rule 14, clause 2, sub-clause 3.6a (amended July 1976); I am able to deploy a Swindonian Swerve and move briskly to Mill Hill Broadway

Our summer house is looking an absolute shambles, @RhubarbFairy, after the St Crispin's Day carnage. Well, you know how it is.

I've pondered long and hard on a move that will satisfy both purists and experimentalists and I think that I'm leaning towards the Kibblesworth Accords of 1863, which were remarkably prescient in their way.

Farringdon

To the best of my knowledge, the Beaverbrook udertaking was never removed form the authorised codicil. (All the apocryphal codicils have, of course, been rooted out.) Therefore, I believe this is the appropriate next move:

Fleet Street

undertaking

Sory
