May I have clarification on how to count the number of cards in a route?
If I start in CARD A, then move to CARD B, is that 2 cards worth of movement or one?
we played it in that way, that we count the starting card and the target card.
So in your example:
There have to be two "shares" in players hands to make a move from card A to card B.
Just my 50 cents.
See the example in the rules which is conducted as above.
