Thanks!

Here are Sunday's games, with the new rule giving more wins than before.

Couldn't a similar tournament also be held on PlayChess?

[Ozymandias]

There's 121 games in the PGN.

11 "wins".

1 game with 1 move and 4 with wrong moves: 2 with e4 e5, 1 with e4 c5 and 1 with Nf3 d5

Wrong Black Moves.
round 2 e4 c5?? oryza-marsell
round 6 e4-e5?? Name-MR-AJ
round 10 e4-e5?? Seliga-MR_AJ
round 8 Nf3-d5?? KQ-MR_AJ

Frozen no second move played and no response.
round 3 Blitzmaster(frozen)-edward

9 wins after that.

3 loses by Marsell
3 loses by Unreal
2 loses by Olivier
1 loss by desvelemosafrica

20 players didn't lose a single game out of 98.

9 loses from only 4 players, leaving the vast majority with a 100% draws isn't what we were looking for. Do we think even more egregious openings are needed? I know some (Arno included) think that with longer time controls, the weak positions can be better exploited, but this seems contra-factual. Any engine room collection of games will tell you that the longer the time control, the higher the draw rate.

It seems that winning is not easy. On PlayChess I had often won against Scandinavian in 5m blitz games (played with large opening books).

Today I tested Scandinavian with black twice on InfinityChess, where I only made the one allowed move. With rest, the engine calculated immediately after 1...d5. My opponent played from the book for a very long time. He still couldn't win at level 11min! Apparently you would have to lower the level so that more games are won.

Here are my two games:
