Vladimir Vukovic showed two versions of a particular kind of Rook and Knight checkmate pattern in his book, THE ART OF ATTACK IN CHESS, (c)1993 by Cardogan Press, Chapter 4: Mating Patterns, under "Typical Mates with Enemy Pieces," page 72, both from within one diagram.

Here is that starting position (note that Vukovic had not placed the White King, however):

The two pending mates were not labelled with names there, but several chess writers have identified them as forms of the Hook Mate. IM Vukovic declares it to be "a typical mating pattern well worth remembering." I have managed to use it in OTB play and like to introduce it to my students as well.

One version of the Hook Mate, which I think of as part of a slash/swoosh, proceeds from the diagram by 1. Rd8+ Kh7 2. Rh8#:

I use the code <SW> for this version of the Hook Mate. The vital chessmen span three files.

Here is the other version, which seems to resemble a sickle or question mark (without the dot at the bottom), as provided by IM Vukovic as a result of 1. Rd8+ Kf7 2. Rf8#:

I use the code <QM> for this version of the Hook Mate. The vital group of chessmen here span only two files.

Note that the Pawn could be on either diagonal "behind" the Knight (away from the opposing King). This point is significant because the SW and QM versions differ only by the positioning of this Pawn.

The code <IV> is for Interesting Variations, those games which do not fit either of those previous types. Most often, a chess piece (not a Pawn) protects the Rook, even from a distance.

This Hook Mate game collection only has games with the defending King and the attacking Rook in the same file, i.e., a vertical orientation, or the same rank, i.e, a horizontal orientation. Of course, this mate most frequently occurs with King and Rook in the same file, but check out this game for the horizontal flavor:

Rouse, Philip vs Henke, Simon
Corr. 2001 23 moves 1-0

CG doesn't have it in their database, so here is its score:

Also, there is a game between two girls in the semi-finals of the Ukrainian championship for U14 that also ends with the Hook Mate in the horizontal orientation:

Poshivaylo, K. vs Breslavskaya, Galina
Lvov, Ukraine 1999 32 moves 0-1 <SW>

Again, CG doesn't have it in their database, so here is its score:

Event "Ch Ukraine"

White "Poshivaylo, K."
Black "Breslavskaya, Galina (UKR)"

ChessCoachClark (CCC) originated this game collection prior to 2015 and he updates it on occasion. This project is a work in progress, culling games from various sources, including several chess training books and personal research. The games are ordered by date (oldest first), not by importance.
