Sorry, Lance, no escape.
Great Portland Street
I reach Mornington Crescent in two moves...
[spoiler]
Heid is in rucksack, KOS can only choose between Heathrow Terminal 4 and Acton Town, which would immediately force a Thameslink breakdown and give me instant MC; you do have your spoon privilege, but even exercising it you reach Kilburn Park via a two-step sidey or Swiss Cottage via a straight linover dump. Both are sure to be countered by Temple, and then it's a forced Chancery Lane for you and MC for me. [/spoiler]
Since I win this one, let's start a new game with
Beckton Park
A bit old-fashioned, I know, but Spanish openings have that uncanny knack of turning wild after the third or fourth move :?
[New game split to
Mornington Crescent 3]
