As I understand it, "advanced" players are actively using the "lighter" from WBN in games... but are their opponents using it too? Because, as I recently heard from one player, when I asked him if he uses the "lighter" in SOD, he said "yes," and when I asked if his opponents always use the "lighter," the answer was "I don't know."
I understand that opinions on this can vary, from, for example, "I always offer to play with the 'lighter'" to "it's the opponent's problem," or simply "what, does anyone else play without it?" I don't know how things are in this tournament with the foreigners... But if one person uses it and the other doesn't, IMHO, it seems a bit unfair.
For "advanced" players, I don't think the presence or absence of the "lighter" is a problem :)
This weekend, I played 2v2 with Spaniards. With 1 minute per turn. There, the "lighter" is really a cheat :)
P.S. The tournament bracket is interesting. Pitu will again have to play against one of the players he has already played against :)
