There are some goings on at the World Othello Championships right now. A couple of years ago, Othello was announced to be weakly solved as a draw, with essentially 5 different proven perfect draw games (see https://arxiv.org/abs/2310.19387). Since that time, the community has come to believe the result (though I still can't work out what precisely was proved), and some of the strongest players have learnt all of the optimal draw games and started playing them against each other. Out of 13 round-robin rounds, there were 5 matches that ended with an optimal draw, all between 5 of the top players. So not overwhelming, but certainly a thing that's happening, and surely something that will only become more common.

There are plenty of options to fix this, assuming people don't want to just have memorised games played out. Japanese-style no-draw tournament rounds (one player chooses either a colour or to win draws, and the other gets the other choice), a football-style 3-points-for-a-win system, and XOT (random estimated-balanced openings) would all be sensible. It is quite funny, though, how contingent these discussions are on a draw being the optimal result. If it had been a point either way, one player would have been incentivised to deviate from the optimal line to trick their opponent, and there wouldn't be such a focus on penalising draws (which would inevitably have to include non-optimal ones, for practicality's sake).
