A constant block with Larisa being silenced (thanks for the game!) would have led to a draw.
You could have blocked once, then eliminated someone (there's no evidence), and then eliminated Larisa, resulting in a victory.P.S. Minus to the GM for changing the rules during the game.
Если где-то чего-то убудет, то в другом месте добавится.
