Ancestor by Scott Sigler

And this is today's challenge,

(It's from the book - 'Ancestor' by Scott Sigler )

Colding, the man is playing White, Jian, the female is playing Black.

Page 204:

"Colding moved his Queen's knight and smiled. "Check"

Page 206 (no other moves had been played in-between)

She set her rook in a new space that blocked his check.

Colding smiled and started to move his knight into attack position,when he
saw that by moving her rook, she had put his king in check with her bishop.

"Checkmate in two moves." said Jian.

(hmmm...blocking a knight check with a rook, that's clever.)

OK. Set up a position and play it our via a PGN where all this is legal.

Adding, when Colding was planning to move his Knight 'into attack
position.' he was actually going to mate Jian on that move.

Here's a rather clunky solution. I'm sure Clifford (aka Big Red Dog Problem) will come up with something a great deal more elegant.

Hi DataFly,

My solution is creaky too but it works.
