A friendly game of Mornington Crescent

With things warming up, let’s play it straight.
Cannon Street

Are you really going to let someone walk this in? Camden Town

If you can do it from Chalfont & Latimer you are a better ambulator than I.

Too idyllic for my current mood, makes me want to rip foxes apart. Better alight in Heathrow Terminals 2 & 3 and enjoy other people’s luggage scavenger hunts. Ah, the smell of jet lag in the morning…

Nice - using the Lost Luggage Addendum from Wilberforce’s Western Line’s Laws. Of course, you realize this opens me up to a move to the north.

Ruislip Gardens

There was a ‘mate in 2’ from this one !

Vauxhall

Not a legal move. Per the Revised New Amended International Rules (Abridged) 2020, one can no longer choose stations beginning with a ‘V’ during the first week of September. Sorry. Which opens up things for some decidedly aggressive moves…Whitechapel

It is a legal move.
Because we’re using the Finsbury/Elkington rules (1977).

Manor House

I would have thought the sheer embarrassment following the Birmingham Incident would forever put an end to anyone wanting to invoke Finsbury/Elkington rules! However, it seems you have some desire to provoke yet another…incident. So be it. Proceed at your own peril. I will not answer for what may follow.

Arsenal

You have been warned.

I refer you to page 248, paragraph 6, sub-paragraph B of Finsbury/Elkington, which clearly states that subsequent rulesets are allowed, so long as they were ratified by a 3/5th majority for tyopgraphical errors or 2/3rds majority for spelling rules. The Revised New Amended International Rules (Abridged) 2020 were ratified by a vote of 13 to 5. Whitechapel stands.

Shepard’s Bush

Oh dear. These blasted 21st century amendments mean I’m running low on the classic blue tokens and my recently ordered Elizabeth Line batch haven’t yet arrived. To minimise the chances of becoming royally swarggoled so close to the finishing line…Southwark

Close to the finishing line, you reckon to be? Not in my book: Finchley Road & Frognal (and be grateful that Slough is not covered by my Oyster Card!)

That masterful move made matters more urgent. According to Rockmetteller’s Rules (23rd edition with notes by Hilderbrand), we are no closer to the finish than New York is to San Francisco.

Crouch Hill

Methinks somebody has jumped the shark.
Rockmetteller’s Rules … New York … San Francisco? We’re not doing that nouveau riche American variant Eisenhower around the US Interstates here. Hell, we can play intergalactic G’Gugvuntts and Vl’hurgs next time if you’re feeling hoopy. I’m frood but this is London Underground. It’s an empirical imperative. So lets get rooted back with the fundamentals.
London Bridge

Redundancy rules! (not capitalizing this one, I beg to notice): Mansion House

Having seen played in quick succession the precursors Manor House and Mansion House whilst no player is in Nib, the ancient Harbringer’s Homestead Rule allows me to play the rarely seen Swiss Cottage to complete the crofters triplet.
Yes, it does nowt to advance this game to be sure but as there can be no living memory of seeing the crofters triplet being played it is a monumentally historic achievement. Yay me!

Carry on.

As much as I would like to congratulate you on your “historic achievement,” I would like to point out that the Crofters Triplet requires the stations to be played in order of the date opened, so no points, I’m afraid.

Hackney Wick

Having been rumbled with a bear up the jumper previously in this game I would have thought a degree of reticence in these regulatory matters might have been appropriate. Whatever.

Swiss Cottage on the Jubilee line opened in 1939, true. However, being originally on the Metropolitan line Swiss Cottage opened in 1868 making it the oldest of the stations in the Triplet. Manor House opened in 1932 is the newest and with Mansion House … well I’ll leave that to you for some bedtime research.
Anyhow I’m not claiming points, I’m taking the kudos.

Hyde Park Corner
One suspects an old hand like @Cardigan might be in with a chance of winning the chocolates from here, alas I think I’m one token short.

Honestly I did not see that one coming. This would seemingly be the time when one would want to, in the words of Spode, ruthlessly press home the advantage. Sadly, I am a single point shy of being able to make the obvious mate in three move back to Camden Town, and must instead fall back on the defensive. I know many out there are staring now at the Jubilee line with their proverbial knives sharpened, and to that end I choose to move to Bond Street. Not only that, but I declare an Escheatment in effect for the next two rounds.

A delicate touch is required here. The Escheatment plus the Triplet Advantage @penultima_thule could have claimed but didn’t (you didn’t qualify for Crofters, but you did qualify for the less prestigious, but still noteworthy, Metayers Triplet - bad luck). Pendlebury-Davenport’s precedent indicates the safest move would be:

Blackhorse Lane
