U.S. Championships

Bad oversight by Anna Zatonskih to lose a drawn game with six pieces left against Jennifer Yu.

[d]1R6/8/3P4/8/1p6/k2K4/8/7r b - - 0 1

In this position, Anna moved her black rook to d1, thinking she would win a pawn. After looking at the resulting position, Anna resigned.
Deasil is the right way to go.

Chest says mate in 8:

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Interesting. Chessbase has a mate in three as an example line. (I posted this long before Chessbase did.) It's surprising that black can hold out that long, even if it is futile.
