why didn't white take the rook instead of dropping the rook for a pawn?

haha, gr8!!

sharp accuracy and right precision is all you need

wow.  who looks at remote possible moves that far down...my brain needs to get faster.  faster faster faster.

isn't Rxb2 dropping the rook? Or is there a ten move checkmate beyond my eyes can see?

In a sense it drops about the equivalent of a rook, but not immediately. White cannot take the rook, as the quoted post just pointed out. Or do you not know what "drop" means?

Uh, in the exact post that you quoted, tonydal just pointed out the seven move checkmate beyond what your eyes can apparently see.

people keep quoting 

Why did black resign? He's not certainly defeated;  both of his rooks remain free.

Actually, both of Black's rooks are en prise, and so one of them will be taken after Black loses the queen.

Both of his rooks remain free? Actually, both of his rooks are en prise and his queen is going to be exchanged for a rook with check. The upshot is that Black will soon be faced with a hopeless R vs Q ending -- he's defeated.

What does en prise mean? Thanks for the help!

en prise is a French term meaning "within grasp," or in chess, "exposed to capture." It usually refers to a piece that is attacked and not defended (or sometimes a piece attacked by a less valuable piece). A piece that is en prise is sometimes said to be "hanging."

And Ozzie, I'm pretty sure black can't avoid a queen-and-four-pawn vs. rook-and-three-pawn endgame, and promoting that h pawn would be so trivial, I don't even think Korochnoi could run out of time if he had thirty seconds left.
