A Whole Rook

KingRogue, playing white out of Australia at the Internet Chess Club, just grabbed the Black Rook at a8 with his Bishop and is up the proverbial "Whole Rook". How this phrase crept into chess parlance is beyond this writer. One rarely hears the corresponding phrases Whole Bishop, Whole Knight, etc. mentioned during raucous kibitzing sessions at USCF tournaments.

Moreover, his Rook,Queen, and other Rook are tripled in that order on the d-file. However, being up in material does not a chess game make! Chess would be way too much like checkers if all that mattered was material superiority.

White's King is stuck in the center which, in this case. more than negates his material advantage. With Black to move, find the shot that exploits a pin that effectively forces the First Player from down under to tip over his King.
