(if I remember correctly, VanjaM has such a chance, I don't remember about Romario).

I calculated it a bit, and it seems that shpilenger still has a chance to meet you in the last round.
But this will happen if VanjaM loses his match in the 5th round, and shpilenger wins his.
But this is just a rough estimate. It will be clear after the results are summed up.

I also wanted to clarify something right away.
As I understand it, you suggest holding the final to 3 wins in the 6th round?
Or can we do it like this:
We play the 6th round as usual, then we sum up the results of the 6th and final round.
The players who take 1st and 2nd place in the tournament table meet in the final to 3 wins, and the players who take 3rd and 4th place play for 3rd place to 2 wins.
All this is by mutual agreement of the players.
I would like to hear the opinion of the players.
I'm afraid of overcomplicating things :)
I just don't quite understand how it will be yet.
And the potential participants, except for R55Max, are still silent.

P.S. By the way, the prizes for the winner and prize-winners are already ready and sent for review to the persons specified in paragraph 3 "Organizational Issues" in the tournament header.
In my opinion, the prizes are exactly what is needed. You can't take your eyes off them :)
