| May-25-03 | | Bears092: I didn't know that Keres played correspondence. |
|
| May-25-03 | | siimens: hey, Keres played a lot of corr-nce, as a youngster and later too |
|
| May-16-06 | | notyetagm: Keres sure knows that <KNIGHTS NEED FORKING SQUARES>. Black To Play: 10 ... ?
click for larger viewThe Black b4-knight has a <FORKING SQUARE> on d3, from which it attacks the White e1-king. The White d2-queen is simply <OVERWORKED>, having to defend both the d3-forking square and the b2-target square. The White queen cannot defend both of these squares, which lie a knight's move apart (b2-d3). Black (Keres) exploits the <OVERWORKED> nature of the White queen by playing the crushing 10 ... ♕xb2!. The point is that if White recaptures with 11 ♕xb2, then the White queen is simultaneously <DEFLECTED> from the d3-forking square and <DECOYED> onto the b2-target square. Black then executes his knight fork with 11 ... ♘x♗+ and 12 ... ♘x♕, leaving him ahead by a whole piece with queens off the board. |
|
| May-16-06 | | notyetagm: Note that if White tries to trap the Black queen in the corner by castling with 11 0-0, intending 11 ... ♕xa1 12 ♘c3, Black can instead simply play 11 ... ♕x♕ <REMOVING THE GUARD> (illusory protection) of the White d3-bishop for 12 ♘x♕ ♘x♗, winning a piece. |

| May-16-06 | | notyetagm: Keres was really born to play the Budapest Gambit, with his overwhelming tactical skill. |

 | | tpstar: Monday Puzzle after 10. Qd2.
<Keres played correspondence> He got his start playing boatloads of postal chess, also testing offbeat lines which frequently worked simply because Keres could outplay his opponent at any stage of the game. |

 | | Phony Benoni: See a fork, set it up,
And all the day you'll have good luck. |
|
| Aug-23-16 | | nateinstein: I went with Nxf2. If Kxf2, Qxf4. If Qxf2, Nxd3+. |
|
| Aug-23-16 | | nalinw: First??
More red herrings than usual for a Tuesday (or is hat why it is a Tuesday and not a Monday as proposed?) 10. ... Nxf2
11 Qxf2 Nxd3+
or
11 K moves N(any)xd3 looks great but
11 Kxf7 spoils it
Then there is
10. ... Nxd3+
11 Qxd3 Qxb2 looks good
but
12 Qe4+ could even lead to mate!
The immediate
10 .... Qxb2 was what I finally came up with but it really doesn't hit you in the face .... |
|
Aug-23-16
 | | FSR: 10...Qxb2 11.Qxb2 (there is nothing better) Nxd3+ wins a piece and pawn. |

 | | Penguincw: Hmm, after missing yesterday's Monday puzzle, how would I fare today? Well, I got it. Yay. I wasn't sure whether to take the bishop first or pawn first, but I saw taking the pawn first was better, and went with it. But what if 10...Nxd3+ 11.Qxd3 Qxb2? Looks like that 12.O-O is best, since 12.Qc3, Bb4. But after 12.Nc3 Qb2 and say, 13.Nd5, it can get tricky. This is why I chose 11...Qxb2. Queen sac, albeit on a Tuesday. 1/2 this week. |

| | FSR: Toldsepp has two games in the database, both correspondence games against Keres. He lost both, in a grand total of 23 moves. See also Keres vs Toldsepp, 1934. |
|
| Aug-23-16 | | Abdunnaser: What about 10 ... Nxd3+ 11.Qxd3 Qxb2 black wins a rock? |
|
| Aug-23-16 | | Infohunter: The stinker was 9.Bd3 on the heels of 8.Qc2. In J Dobias vs F Zita, 1933 White played 8.Qd2 and, after Black replied 8...d6, continued 9.Nc3 and ended up winning. |
|
| Aug-23-16 | | Infohunter: <Abdunnaser: What about 10 ... Nxd3+ 11.Qxd3 Qxb2 black wins a rock?> Not really; 12.Qc3 thwarts that plan. |
|
| Aug-23-16 | | Olsonist: In correspondence? Really? |
|
| Aug-23-16 | | coulapic: <Infohunter: Not really; 12.Qc3 thwarts that plan.> 12.Qc3? Bb4! |
|

 | | Dionysius1: I went for 10...Nxf2. If 11 Qxf2 Nxd3+. If 11 Kxf2 Qxf4. If 11 Rf1 N(f2)xd3. So Black wins lots of material. |
|
| Aug-23-16 | | BxChess: Like <Abdunnaser> I considered 10...Nxd3+ 11.Qxd3 Qxb2. I saw the response given by <coulapic>: 12.Qc3? Bb4! I was more concerned with 12. Qe4+. But as far as I can tell 12...Kf8 puts an end to the checks and leaves the white rook to be taken. |
|
| Aug-23-16 | | agb2002: Black is one pawn down.
White is about to castle.
Black has several options:
-10... Nxf2, to keep the white king in the center.
-10... Nxd3+, to deflect the white queen from the second rank. -10... Qxb2, to deflect the white queen from d3.
-----
The simplest option seems to be 10... Qxb2:
A) 11.Qxb2 Nxd3+ and 12... Nxb2 - + [B].
B) 11.Bg6+ hxg6 12.Qxb2 Nd3+ as in A.
C) 11.O-O Qxd2 (11... Qxa1 12.Nc3 Qxf1+ 13.Kxf1 Nxd3 14.Qxd3 O-O 15.Qd5+ Kh8 16.Ng5 looks very bad for Black) 12.Nbxd2 Nxd3 - + [B]. D) 11.Qc3 Qxc3 (11... Nxd3+ 12.Qxd3 Qxa1 13.Qe4+ is unnecessarily complex) 12.Nxc3 Nxd3+ ends up a piece ahead at least. E) 11.a3 Qxd2+ (11... Qxa1 12.axb4 gives White some chances) 12.Kxd2 (12.Nb(f)xd2 Nxd3+ as above) 12... Nxd3 13.h3 (13.Kxd3 Nxf2+ and 14... Nxh1 wins decisive material) 13... Ngxf2 14.Rf1 Nxf4 - + [2B+P vs N]. F) 11.Nc3 Qxd2+ as in E.
G) 11.Be2 Qxa1 12.O-O Qf6 13.Bg5 Qf7 and White doesn't seem to have enough compensation for the rook. |

| Aug-23-16 | | Infohunter: <coulapic: <Infohunter: Not really; 12.Qc3 thwarts that plan.> 12.Qc3? Bb4!>
Oops!
And wouldn't you know it--I just pulled that exact type of stunt on somebody less than a week ago, and still missed it here! Go figure. |
|
| Aug-23-16 | | dfcx: was first looking at 10...NXd4 11.Qxd4 Qxb2 but white saves the rook with Qc3. Switching the order of moves,
10...Qxb2 11.Qxb2 (Qc3 Nxd4+) Nxd4+ gets the queen back plus a bishop along the way |
|
| Aug-23-16 | | dfcx: the early morning really gets me, I meant Nxd3, of course. |
|
| Aug-23-16 | | Infohunter: OK, how about this: Perhaps White could hold his loss to "only" a Bishop by answering 10...Nxd3+ with 11.Ke2 instead of 11.Qxd3. But of course he still would have a lost game. Thoughts? |
|
| Aug-23-16 | | The Kings Domain: Always loved those knight forks.
Gotta be amused with white resigning at once. |
