Don't understand why white resigned In the 2017 Women's World Chess Championship match (Round 3, game 2) between Yang Shen (white) against Nana Dzagnidze (black) I don't understand why white resigned. There was not a time control issue and it appeared that white could at least get a draw.

The game ended in a draw. Chessbomb isn't an official source, but it recorded the game as a draw, and the comments there indicate that the game was originally reported (by the digital board, perhaps) as a win for Black, but it has been corrected to a draw. These glitches happen from time to time.

As for the position: it doesn't seem possible for white to escape perpetual check, and black cannot force a mate and is far behind in material. Therefore, it's a draw.
