A little strategy based on the logic of the game and those games that have already been played.
Obviously, in the absence of kings, checkmate is impossible. Therefore, try to postpone the appearance of rooks and queens as late as possible.
One pawn can generate six knights. Therefore, strive to destroy the opponent's pawns. If there are no pawns, there is no evolution.
The advantage of the first move does not matter at all here, since by making the first move you trigger a self-destruction mechanism - sooner or later all the pieces evolve, filling the surrounding space, and collapse occurs. If you let your opponent do it first, you have won. The paradox of the game is that, on the one hand, you have to fight for living space constantly, increasing your strength and power, and on the other hand, do not become a victim of your own strength and power.
Oh, let's welcome the first lady in town! You need more queens, you need more queens! lol

This may seem like a suicidal move, but there is a clear logic to it. In the game where a stalemate is not a draw and a repetition of moves is a loss, promoting a pawn to a king makes sense.
