Playing against myself, I successfully forced a checkmate against a lone Queen with a Queen and two Dragons in 47 moves. To show that a Queen and two Dragons could force mate on a Queen, I played Black with full knowledge of my strategy, resisting it at every move. I might be able to force mate in fewer moves if I tried it again, as I was trying to figure out what to do while doing it. The trick is to force the lone Queen to move to the one part of the board where the two Dragons can work together to checkmate it. I started with the Black Queen on its initial rank, where the White Queen and Dragons could not touch it. But they could inch closer to it until it had nowhere to go except off its initial rank. To do this, the White Queen moved to the seventh rank, inched closer to the Black Queen, forcing it to the side, then a Dragon blocked the White Queen's line of attack on part of the seventh rank to give the Black Queen a space to move to. The White Queen could then occupy the last rank, keeping the Black Queen from returning there. The next part was to force the Black Queen down to White's initial rank. This was mainly done with the Queen, with Dragons moving mainly to avoid stalemate situations. Once the Black Queen reached White's first rank, the White Queen stood guard on the second rank to keep the Queen on the first rank. The Dragons then moved down for check and checkmate. If a Dragon was captured and returned through promotion, the place on the board where the Dragons can work together would be different, but the principles behind the forced mate would still be the same.
