interesting how the advantage varies throughout the stages of the game
Yes, Xccowan, basically if White can survive the middlegame, White wins.

I wanna play!
Rychess, you have a diamond next to your flag. I think that means that you can set up your own tournament.

I think 6...dxe6 is wrong and it would be the right moment for a Queen sacrifice: 6...Qxg5, 7.fxg5, Qxg5. I think black then has good chances of winning. The Queen sacrifices otherwise come too late when white has already developed his defense structure and the Knights.

Yes, McGoohan. In Knights vs Queens, Black must sacrifice some queens and before White can develop a defense. Strategically you are 100% correct.

I played this variant in a tournament last year https://www.chess.com/tournament/knights-and-queens-unrated/games and won all the games. My impression is that white has a small advantage and a better chance of winning than black. But only if white makes no mistake at all. Because even a very small mistake has a fatal effect and happens quickly. So this means that a very good player with white is more likely to win, while a game with "average" players is more likely to win black. This is a bit paradoxical, because the game is "unbalanced", depending on the strength of the players.

Here are some stats:
0-1 moves = 40 games played (obvious forfeits)
2-9 moves = 7 won by White, 7 by Black (early forfeits/resigns)
10-19 moves = 5 won by White, 25 by Black (Black has middlegame advantage)
20-29 moves = 14 won by White, 40 by Black, 1 draw (Black still has advantage)
30+ moves = 44 won by White, 28 by Black (White has the better endgame advantage in the position)
