If you draw the "Take a trip to King's Cross Station" Chance card, do you move your piece forwards or backwards? The logical answer might be forwards because most Monopoly Chance cards say "advance". However, in the case of this card, it says "If you pass go"; you would always pass go when moving forwards from a Chance space to King's Cross, so what’s the use of the word "if"?
Note: This is London Edition Monopoly; this space and card are the equivalent of Reading Railroad and the "Take a ride on the Reading" Chance card in standard edition.
