|Nov-09-09|| ||Manic: <FlashinthePan> Sorry to spoil your fun, but 23.Kxg1 wouldn't be funny at all if your black.|
|Nov-09-09|| ||I Like Fish: Knight to gee-three...
|Nov-09-09|| ||remolino: I am surprised everyone's thought process was so intricate and complex for such a pitifully simple mate.|
My thought process was. Queen covering g1, N can check on g3 and open h file, is there a rook to check on h file, yes, done.
Anyone who took more than 30 seconds today should have cofee before looking at the puzzles, it is only Monday.
And anyone who played Nf2 should take some vacation, it is much needed.
|Nov-09-09|| ||gus inn: the temptation of the smotehred mate (which does not wotk) is the charming part of this puzzle.|
|Nov-09-09|| ||stacase: After a minor amount of checking out White's threat to fork the King and Queen, my attention focused on the fact that White's King has no place to go if checked. Hmmm Black's Knight can check from two squares, which one works? Oh, I see, 22...Ng3+ forcing 24 h3xg3 allowing Black's Rook to seal the deal with a move to h8+ White's Queen can interpose but then RxQ++ |
I would most certainly see this one over the board.
|Nov-09-09|| ||gtgloner: 22. ... Ng3+ and the pawn must take, whereupon the black rook mates. Let's see.|
|Nov-09-09|| ||TheaN: Monday 9 November 2009
Birdie: -10s <> -1m
Material: White up, 2
Candidates: Nf2, <[Ng3]>
Expected from someone like Diemer to be two pawns down, in this case it works. The most abundant move to play is 22....Nf2, as this is the starter for the smothered mate: 23.Rxf2 is necessary, as 23.Kg1?? Nh3 24.Kh1 Qg1 25.Rxg1 Nf2 ends the game, but after 23.Rxf2 Qxf2 it is Black in trouble after 24.Qh5, and even without it it is still an exchange against two pawns. As such, another threat must be found. It doesn't take long to see that the h-file can be opened with a deadly end because the Black Queen obviously guards g1, and so it happens forced:
<22....Ng3 23.hxg3 Rh8 24.Qh5> the White Queen still ends up on h5, but now in quite a different setting compared to the smothered mate combination:
<24....Rxh5 0-1> time to check how the complete game went.
|Nov-09-09|| ||johnlspouge: Monday (Very Easy)
Reichert vs E J Diemer, 1950 (22...?)
Black to play and win.
Material: Up 2P. The stalemated White Kh1 invites a Greco mate along the open h-file.
Candidates (22...): Ng3+
Ng3+ 23.hxg3 Rh8 24.Qh5 Rxh5#
|Nov-09-09|| ||TheaN: 1/1
19....g6 is dirty, but 22.Nxf8 seems to refute it fair and square. I guess Diemer was going to play 22....Bd7 with the same threats, but I guess White is more than okay then.
|Nov-09-09|| ||TheaN: No, I just checked it with Rybka and of course, 22.Nxf8 Bd7? 23.Rf3 and the Black combination ends with a material deficit to boot. After 22.Nxf8 Black will end up with a lost endgame after 22....Qg5 23.Ne6 Bxe6 24.Bxe6 Rh8 25.h3 Ng3 (what else?) 26.Kh2 (26.Kg1 Qe3=) Nxf1 27.Qxf1 |

I don't like to be Black here. Improvements seem hard, and 22....Qh6 evaluates well over +1,5.
|Nov-09-09|| ||Patriot: I looked at the possibility of a smothered mate and very quickly dismissed it--the recipe just isn't there with a rook on f1. Then I thought black could win the exchange, but set that move aside and looked for the next check, 22...Ng3+. 23.hxg3. Can I bring a rook over to the h-file? Yes, so 23...Rh8#. Wait...24.Qh5 is possible so then 24...Rxh5#.|
That's pretty close to my thought process.
<remolino> I like your assessment. Thanks for the chuckle! :-)
|Nov-09-09|| ||patzer2: It's Monday and mate-in-three with 22...Ng3+! for the puzzle solution.|
|Nov-09-09|| ||DarthStapler: Got it easily|
|Nov-09-09|| ||dumbgai: <sfm: <WhenHarryMetSally: Monday is the only day I can actually get. Thats why I hate Mondays.> No way!
If you can get Monday's you can get Tuesday's too.
Believe me, if you can get Tuesday's you can surely get Wednesday's. For those who can find Wednesday's Thursday's not much harder. Etc.
Keep on trying! The day when you can hate the whole week is not far away!>
In my opinion, the biggest jump in difficulty usually occurs between Wednesday and Thursday.
|Nov-09-09|| ||Patriot: With 22.Nxe7??, it seems that white was trying to get his material back and leave himself with a few extra pawns for the exchange after 22...Nf2+?. But that turns out to be a "hope chess" move by a strong player, leading to a simple puzzle position.|
22.Nxf8 almost looks like a blunder because it doesn't win back a whole piece outright. Black could play 22...Bxf8 or 22...Kxf8 and be ahead materially. After 23.Qh5, dynamics rule over the material deficit and it is white who is winning.
|Nov-09-09|| ||waustad: <Patriot>Ditto.|
|Nov-09-09|| ||VincentL: Well. immediately I see 22.... Nxf2+ 23. Rxf2 Qxf2, winning the exchange.|
If 23. Kg1 the queen goes, 23....Nxd1
But is this what we are meant to see? It seems too simple even for a Monday.
A smothered mate in the corner is not possible.
Ah... now I see 22.... Nxg3+ 23. hxg3 (only legal move) Rh8+ with mate next move.
Black will have played this second line. Let's check.
|Nov-09-09|| ||VincentL: This is a combination by white gone wrong. Above all, white has failed to notice black's threats (how many times have I done something similar myself?)|
|Nov-09-09|| ||VincentL: <Remolino>I almost got the vacation.|
|Nov-09-09|| ||Chessforeva: 3D: http://chessforeva.appspot.com/C0_p...|
|Nov-09-09|| ||A Karpov Fan: got it|
|Nov-09-09|| ||CHESSTTCAMPS: Black, on the move, is down a pawn and has a badly exposed king, normally a serious flaw. However, white's king is also seriously exposed and black has two decisive advantages: the all-important initiative and a vastly superior queen position. In fact, black is in position to force mate with a familiar sacrifice to open a critical line to white's king:|
... a little like a back-rank mate executed on the side of the board, with the queen controlling the escape square.
A couple related challenges for novice and more advanced players, respectively:
(1) Move white's Rf1 to e1 and put white's queen on h5. How should black continue?
(2) Move white's queen to the active square h5 and leave everything else the same. With black to move, find best play for both sides.
|Nov-09-09|| ||chrisowen: A wild state of play but black needs to hoof it a bit. Get the horse checking on g3 then Rh8. The feral Diemer renowned for gambits does ease
away in the end.|
|Nov-09-09|| ||laskersteinitz: <a little like a back-rank mate> Yeah, that's called a "corridor" mate.|
|Nov-09-09|| ||kevin86: A twist on the usual queen-sac-monday. This time a knight goes down to open a door to the adverse king.|
