Here’s a weird chess game: one in which I ended up with three queens.
I kept thinking Oscar (the Duolingo chess program bot) would throw in the towel and resign, but no.
He let me promote two pawns to become queens, and then let me checkmate him.
(Note: Yes, Oscar is obviously not a grandmaster. I will have to keep playing and be patient. He is supposed to improve his chess prowess if he gets beaten too frequently by me.)
I had a queen and a rook, (and an extra pawn), and Oscar had nothing. He should have already resigned three or four moves ago, before two of my pawns reached the eighth row, and were promoted to queens.So I simply boxed his king in with two queens, and then delivered check mate. The player with an overwhelming advantage need to be careful to avoid a stalemate (a draw). A stalemate happens if the player whose turn it is has no legal moves (such as a move that will put the king in check).
