Tiebreaks are not included.

Transpositions count (that is any game where the position is the same after the right number of moves counts, even if the moves come in a different order).

Add options but be sure to list the moves to remove ambiguity (or at least the last move if there are too many e.g. you can do "Marshall Attack 8 c3 d5"). The options do not need to be mutually exclusive, we can add sub-variations.
