No point in wasting time with slow knight moves: For the truly power hungry, you can have your King and seven Queens and battle to a bitter pawn endgame, unless you're savvy enough to force checkmate before then.
The game starts with the following setup
All standard chess rules are in place, where possible. Of course there is no castling.
While only queens are available initially, it is possible to promote to the other pieces (you can promotea pawn to a knight, for instance).
In most of the games players build up pressure, piling up the queens in the enemy camp, finally reaching massive queen exchanges. Then, players usually end up playing a queen endgame - most frequently having 1-2 queens each, and 5-6 pawns (note that one usually has more pawns here than in a typical standard chess queen endgame).
Keeping the king hidden and its shield protected is crucial, with hordes of queens there is no room for the king to become active.
Watch out for double attacks and calculate carefully the numbers of attacking and defending pieces!
Do not underestimate the pawns. The queens will be - sooner or later - exchanged, leading to the endgame. Then the extra pawn, especially a passed pawn, can be decisive.
Queen Me - both players try to induct weaknessess in opponent position, but also defend carefully, the game ends in a draw when nobody is able to make progress without risking too much,
Little pawn - complicated queen maneouvres and exchanges let white win one little pawn, in the resulting endgame its march turns decisive.
