LT League vs Heroesworld.ru

Does Vitalik agree to continue the game if Suris plays differently?

It seems he doesn't agree. But in that battle, Suris would have the advantage; the battle was won due to his mistake (in my opinion). I personally wouldn't replay the battle.

They can only save the match, and nothing more...

And tell everyone what dishonest scoundrels Russians are.

This rule always applies, even without being written down; it's more of an unwritten rule.

I also thought so, which is why I didn't pay much attention to translating this rule. =((

Put pressure on them; Lithuanians aren't Poles; they should acknowledge your rightness.

No, they persistently demand that the last match be played/finished.
