Originally posted by GarybearSorry to be pedantic, but that's not quite the whole picture. It's stalemate whenever the player to move, though not in check, has no legal moves. This can happen in several different ways, of which yours is just one example, though it is the most common.
A Stalemate is when a player has no other piece to move other than the King and while the King is not presently in check, all available moves would be moving into check. The game ends there without a winner.
Anyway, in answer to your question, I think RHP recognises it automatically, it doesn't have to be claimed. When you make a move which stalemates your opponent the computer declares a draw and the games ends without further input.

Black to move.
Although in fairness to GaryBear he says "has no pieces to move other than the king" not "has no pieces other than the king".
Originally posted by DeepThoughtTrue, but he also says that stalemate means that "all available moves would be moving into check". It's also stalemate if there are no available moves, moving into check or otherwise. Admittedly this rarely if ever occurs in practice, but it is possible, as someone demonstrated to me on another thread recently.

I did say I was being pedantic, didn't I?
The RHP robot recognizes and announces the stalemate automatically
after the last move.
See Game 2780984 and Game 2780985.
