Curiouser and Curiouser . . .

Last week you were presented with the following position as a puzzle, with black to play and win. As revealed in the comments, the winning move was the rather lovely 16...Bd1!, intending 17.Re3 Bg4 winning the exchange.

I had never before seen a position where one player managed to get a piece to his opponent's back rank, without a single piece having been removed from the board.

Wondering if this was indeed a unique occurrence, I emailed intrigue-expert Tim Krabbé to find out. Joyfully, Tim replied with this lovely second example, presented here for your amusement:

The aficionado of the chess curiosity will also be pleased to note that black resigned without a piece having been taken, and that after 11.Bh8! white had every single one of his pieces on the edge of the board.

Let's just savour that moment again . . .

(PS. You know, there really should be a name for this kind of thing. Any suggestions?)
