Mate with K+N

This game received a great deal of notice some years back but not for the normal reasons but for a new kind of mate which gave us a new name (or old) in the literature. Stama's mate. (possibly Stamm) check the last eight moves or so.

ArturoRivera: Brilliant!!!, white should have felt like the god chess by winning this. Just imaging

After 80.-Kxa2, black was calm, -i got a draw at least, i must be good to have get out of this difficutl position i had-, finally he asked white: draw?. White stares at the position a while, maybe ten minutes, no answer, silence in the room, some spectators pass watching the games from those strong tournament boards, they dont even pass a minute with them, -a sure draw- they assume. Then Nogueiras just laugh, calmy, impressed maybe by his own idea, perhaps Gongora dont know why, -draws are funny? he said, he smiled too. after 2 more moves Gongora stop smiling, he is staring at the board, astonished, cant believe it, he seeks all probabilities, watch all variants and his smile suddenly dissapear. his hand trembles, slowly directs to it, the clock stops, the room in silence...

The name is Stamma and apparently occurs in endgame studies with some frequency.

Beat me to it. I was about to do the same thing. 🙂

No matter, as long as it got posted. Have you found any other games with this form of mate? (K+N)

How the hell did you shorten the text?

One last shamelessly borrowed comment and I'll shut up about it:

Peligroso Patzer:

According to the following tablebase (for positions with six or fewer units, including Kings): http://www.k4it.de/index.php?topic=... , Black was lost as least as soon as he sacrificed his Knight for White's f-pawn (75. ... Nxf6). The point, I think, is that White will either be able to outflank Black’s King (using the Knight for tempo moves, if needed) and win the a-pawn (after which King plus Knight plus Rook-pawn versus lone King is an easy win) or make sure his Knight is on a light square at the time Black plays … Kxa2. Here are some representative variations: 77...Kd6 78.Nb8 Ke5 [78...Kc7 79.Na6+ Kb6 80.Nb4 Kb5 81.Nc2 Kc4 (81...Ka4 82. Kf4 and Black’s King must leave the defense of the a-pawn and allow 83. Nxa3) 82.Nxa3+ Kb4 83.Nb1 ] 79.Na6 Kd5 80.Kf5 Kd4 81.Kf4 Kd3 82.Ke5 Kc4 83.Ke4 Kb5 84.Nc7+ Kc6 85.Nd5 Kc5 86.Ne3 Kb4 87.Kd4 Ka4 88.Kc4 Ka5 89.Kb3

I had one in a tournament last year. I'll see if I can dig it out.

Don't know of any other games like that off the top of my head.

As for the text, you referring to the post that I have replied to? That happens automatically when you reply and quote someone.

That is a brilliant game. It's as if the King is about to willingly step off of a cliff at the end.

Oh.

The game shown does not end in checkmate. What am I missing?

EDIT - Oh, I see it now.
