White has no legal moves, therefore it's a stalemate. Don't worry, we've all done it when we were beginners. Let me find the help article for you...
Stalemate?
One queen is plenty. Dont over do it with the fire power. Stalemate is always a risk when the are many long range pieces on an open board as they can easily control squares round the king without you realising. Google how to checkmate with a King + Queen vs King. I use the 'L' technique which is easy to remember. Once you know this, you'll be confident with just one queen.
I'm kind of new but this game ended as a stalemate, playing as black, and I'm not sure why. Any help would be great!
