Smothered mate
I have been playing chess seriously for a couple of years now, and played possibly a few thousand games, but never have I either won by a smothered mate or lost by one. I have solved puzzles in which the solution is one, but it has never happened in real play, are they really that rare or is it just me?

I have seen people lose by smothered mate in the Caro-Kann about 1/2 dozen times in the last 40 years.

1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.Qe2!? Ngf6?? 6.Nd6#.

I have been able to mate using the combination known as Philidor's Legacy several times, and have seen it done numerous times.

i've done the same sort of mate in the budapest opening as black in a fast OTB tournament once.
it takes a couple of more moves, though:

1.d4 Nf6 2.c4 e5 3.dxe5 Ng4 4.Nf3 Nc6 5.Bf4 Bb4+ 6.Nbd2 Qe7 7.a3 Ngxe5 8.axb4???, Nd3#
If White plays e3 instead on move 8, he's doing fine of course
.
I've since given up on playing the Budapest pretty well, but I could look into it again some time... I don't think it's so bad.

I forget where I read the quote, but I remember someone saying that for as important as the smothered mate is, an average chessplayer will only experience it once in actual play. I've come close to arriving to an actual smothering situation once against my dad, but it never materialized.

It is rather rare. And on the flipside, I'd venture to say that the King+Rook vs. King mate is probably the most common mating scenario.

I used it in 50% of my games on ICC, here is one from last June:

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. d3 Be7
6. O-O d6 7. d4 exd4 8. Nxd4 Bd7 9. Nxc6 Bxc6 10. Bxc6+ bxc6
11. Nc3 O-O 12. Bg5 Nxe4 13. Bxe7 Qxe7 14. Re1 d5 15. f3 Qc5+
16. Kh1 Nf2+ 17. Kg1 Nh3+ 18. Kh1 Qg1+ 19. Rxg1 Nf2#

Then again - I played only two games there  

Usually it is something both players see coming during the calculation of variations and they take evasive action - so it hardly ever materializes.

Sveshnikov
There is a few possibilities for black to strangle himself in the Sveshnikov, e.g. something like this:
1.e4, c5. 2.Nf3, Nc6. 3.d4, cxd4. 4.Nxd4, Nf6. 5.Nc3, e5. 6.Nbd5, d6. 7.Bg5, a6. 8.Na3, b5. 9.Bxf6, gxf6. 10.Nd5, f5. 11.Bd3 and now it is possible, but certainly not good to play: ...Ne7 to challenge the important d5 square and cover f5 at once. However white chuckles and plays 12.Nf6# since the Q no longer defends f6.
I've been on that side of the black position in a blitz game or two...
And I made a smothered mate OTB in a game where I had 5 minutes and my opponent 55 minutes (due to rating difference and compensation). I used exactly 63 seconds to do that for the whole game

In the first example provided by heinzkat and in the example of pgroenborg the mated king has one empty square, i.e. the surrounding squares are not all occupied by his own pieces.

I thought the definition of a smothered mate was : A checkmate delivered by a knight in which the mated king is unable to move because he is surrounded (or smothered) by his own pieces.

But if we allow cases where the mating knight also covers an escape field, then the amount of examples increases. For instance game

...
I think the definition of a smothered mate is where the knight delivers mate on its own, due in part to the king being blocked by its own pieces. As far as that goes, I think heinzkat's first example is a fine one. There can probably be disputes about a pure smothered mate, I suppose, if there is a piece being prevented from capturing the knight due to a pin.
algol
16-Jan-09, 19:45

...
Not that it matters much but du Mont in The Basis of Combination in Chess and Renaud and Kahn in The Art of the Checkmate say that the King needs to be deprived of all flight squares by its (sic) own pieces or pawns. The first source talks about a semi-smothered mate if a flight square is not obstructed by the King's own men. A mere technicality and I find both types beautiful.

This game was quite cute too
algol
16-Jan-09, 20:33

Yes, good pawn break 15. d5. The game was played quickly I see. Nice of you to allow your opponent to execute the mate heinzkat. Or were you trying to get your number of smothered mates up?  
pgroenborg
17-Jan-09, 04:27

algos's definition is correct
... I got carried away and thougt about the semi- smothered mates in sveshnikov, but it doesn't change the fact that I have played on both sides of it, but only in blitz and fast games.

I've performed one live in a friendly over the board game once; but it has never happened during a competitive game that I've played. But then again, I don't have much real competitive experience because I've shunned it for the most part.

This was as close as I've come to being the victim of smothered mate. I'm white, gothicgirl black. I was on top of the game with a strong attack, and I wanted the g2-b7 diagonal clear for my final assault, so I played f4 with the intention of shifting the knight, with the follow up move e5. gothicgirl played Ng4, and I so nearly instantly moved the pawn. I stopped in my tracks and realised how big a hole I was on the brink of falling into... I played Rb5 and gothicgirl's counter-attack fizzles into nothing. Phew.

Looking back, perhaps Nd3 is better, as it threatens the same mate, while bringing the knight into defence where he is badly needed. But that's an irrelevant side point.

I have once won with a similar smothered mate, can't remember my opponent, but I lured him into it with a rook sac I think.

It's certainly rare, but important knowledge as it can crop up when you least expect it...

Clearing the g2-b7 diagonal was just a bad idea. 1. Rxb7+ Qxb7 2. Qc2 and White win with the pin. But after 1. f4 Nc4!! and gothicgirl could have won with the fork at d2. Oh well!
tugger
03-Feb-09, 05:55

That fork is interesting, but I'm not sure it wins outright for black. Certainly is is better than the line chosen, though. My analytical skills have improved since this game, and I can now see that f4 was not a great move at all. But it does seem that the play is still with white, even after Nc4. A rook sac on b7 makes life very interesting, but white is now chasing the material before his attack is complete. Most lines seem to show the knight will be reclaimed at the very least, but maybe black has an escape.

It is interesting to see what gets missed in old games! This one was just a case in which I remember nearly falling into the smothered mate trap. The funny thing is if gothicgirl had not spotted the smothered mate potential, perhaps she would've found the right move to counter.

Having a look at how the game actually went, this position crops up a couple of moves later...



I played 27. Bxb7+!
I seem to remember spending a good bit of time looking at Rxb7, looking at the various mating nets thinking it was forced mate in 6. I soon realised it was actually mate in 5... for black. There's that smothered mate again...
27. Rxh7? Qc5+

Had this tasty mate a long time ago against a fairly terrible opponent, but the mate was nice all the same, never happened to me since

SMOTHERED MATE INVOLVING QUEEN SACRIFICE!
Just a few days ago I had this sweet (and classic) smothered mate involving a queen sacrifice! See game below.

Another Smothered Mate today in 3 minute blitz ...
gameknot.com
**************************************************************
Pascal ... Congrats on your nice variant of Philador's Legacy, for your Smothered MATE !
***************
About the rarity of Smothered Mates mentioned; as I understand it to be a proper Smothered Mate, the pieces surrounding the opponent's King must all be of his own color.

So that leaves out positions that have any of the attacker's pieces touching the enemy monarch. I suspect that those, together with positions where the King in surrounded except for one square BUT that one gets covered by the Knight that mates at the same time its check is delivered; would add considerably to the Smothered Mate count if permitted. Perhaps twice as many ?!

I don't know, but to my sensibilities, the former is at least equal in beauty to a proper Smother, since the Mater had to figure out how to put that blocking piece there, which only addes complexity. And about the Latter, I find it very pretty when the N not only mates but covers the flight square. There can be only 2 squares on the board from which it can do that in any given position, as well. Making it all the harder to do.

I've had several dozen Smothered mates at least. Mostly blitz tho, or fast Chess in general. And that is from 42 years of play. And more than 20,000 games since starting online Chess here and another blitz site. One thing I can say, my count went up dramatically from several themes.

One of course was learning Philidor's Legacy. This must have more than doubled them. The other is knowing of traps in the opening which permit it if the opponent is being hasty & thoughtless. The best being the Caro-Kann trap pointed out by Blake78613 . Which also works in the 2 Knights Attack where WT does not play 2.d4 but rather Nf3 (and Nc3). Qe2 can still be played for that same mate.

Blake mentions seeing a half-dozen from it(!). Yeah, it seems particularly effective vs players that don't get their head into the game from the start. After all, they are play the SAFE, POSITIONAL Caro-Kann ... What's to Worry?! lol.

And besides being especially effective in its malicious intent, the thing also PLAYS pretty well even if they don't fall into the trap, and probably makes a position WT is more familiar with than the Caro player ... who may also take extra time trying to refute the opening. I've played it vs a State Champ calibre Expert tho, in a tournament. And I lost the game, because Kevin ALWAYS beats me. The opening tho, was fine. Even favorable, if I am remembering the correct game from 25 years back. And it caught an "A" in the trap in tourney. So it is worth knowing those if you are going to go hunting Kings to smother.

I just Might be tempted to play the Caro trap line in a Corr Chess game someday. Not thinking they would fall into the trap, but as a probably 2nd rate line that I would presumably know better than the opponent, which I feel would hold thru the opening an make some novel play. (Consider the 2.Qe2 of Tchigorin vs the French).

It must be my day for Knights !?
Here is another Knight Mate, but I do NOT know what to call it? Perhaps if it has no name, we at GK should do it the honor of christening these "almost Smothered Mate"s ?

Tho this one seems not too air-tight, but gets the job done. But truly, what to call the ones where one of the pieces smothering is not the opponents? Or where a Knight checks and covers the flight square simultaneously? (I'm thinking that one be "The Open Barn Door Mate", getting jumped on by a horse slipping thru a crack like that!?)
*****************************************************
gameknot.com
*******************
Here are some ideas I had:

Semi-Smothered Mate
Pseudo-Smothered Mate
Water-tight Mate
Strangled Mate
Gasping For Breath Mate
Non-mono-chromatic Mate

As you can see, I need some help with this one. Ideas, Please ! And if we can come up with a couple reasonable ones, I will officialize the christening by sending the new name to Jeff Peterson, aka bucklehead , who is the official "Writer I send all new words and names to" whom you may recognize as also being the creator of the Peterson Defense, of Anti-Danish fame. Think quick and dont passed up this chance for Chess immortality. (I can assure you it will be credited to the inventor each time it is mentioned by the official-self-appointed-name-dropper-of-GK as well.   )

The thing about smothered mates is
That my opponents usually see that they are threatened. So there have been occasions where they could nearly be used but both players have enough expiernce to recognise the pattern and thus avoid them which would partly account for why they dont often crop up.
baronderkilt
26-Feb-12, 18:54

True ... People tend to look for MateInOne's lol
It is very hard to sneak up on a King with a Knight! Unless perhaps as a final kicker at the end of a combo, like Philidor's Legacy ...

I had my first smothered mate
a few weeks ago. But just now when I tried to post it, it said that game had been deleted or cancelled???? anyway, I don't think I would have ever noticed the possibility to sacrifice a Q and then move the N in for a smothered mate if I hadn't been doing chess tactics. Thanks for the tactics and puzzles GK.
