I have seen this happen a few times. The first I published and annotated in the July 2000 issue of Gothic Chess Review. There is no corollary associated with play other than the knockout punch.

Here is the other game:



David Vales vs. Biju Samuel

1. i3 d5

Dave often plays i3 at the start of the game to invite the Pawn push that reveals the Bishop’s attack on the Rook. It is a short-lived attack.

2. Nh3 h6

The geometry of Knight-Pawn spatial relationships indicates that any singular push of a Pawn one rank from the starting position will functionally disable an enemy Knight’s ability to advance two ranks closer on the next move. White’s Knight on h3 is so stymied by Black’s h-Pawn.

3. Bi2 i5

This is a favorite Pawn push of Biju’s, aimed at dislodging the Knight on the h3 square. With the exposure to the King created by ...h6, White crafts a plan to use the tempi lost by Black in dispelling the Knight to move it closer to the King, then “hope”....

4. d3 i4
5. Nf4 c6?

Black is missing the point. The dislodging of the Knight was not a positive realization, and it is most dangerous.

6. Cf3!

A very, very sneaky move! White has set up the deadly revealed check.

6 ----- Nj6??
7. Ng6#
