|Sep-03-15|| ||cocker: Wonderful combination, not sure I would have got it had I not already seen it.|
|Sep-03-15|| ||Abdel Irada: Too hasty again!
Glancing at the diagram, I found the obvious
27. Kc1 ...
But then I continued with 27. ...Qxb2+!?
28. Kxb2??, Nc4++ 29. K any, Ra1#.
Of course, White doesn't have to take the queen. :-S
|Sep-03-15|| ||sfm: A mate in 4 with all checks and one forced response on all of them - is bound to be a relatively easy Thursday puzzle.|
Patzer sees check(s), patzer gives check(s) - and patzer wins! And with a pretty mate too. For some reason which I will never know I liked 29.-,Nd3
|Sep-03-15|| ||whiteshark: <27...Qxb2+> Count me in!|
|Sep-03-15|| ||framsey: Simple forced mating sequence:
26...Qa2+ 27. Kc1 Qa1+ 28. Bxa1 Rxa1+ 29. Kb2 Nd3 double check mate!
The final position is a standard B+R mating pattern (sort of a dovetail mate with the bishop providing both the check and x-ray defence of the rook). All moves by black are forced, making it easy to calculate. Seems a bit easy for a Thursday.
|Sep-03-15|| ||framsey: Of course, the final move can also be Nc4 as in the game. I wonder if there is some psychological significance to the choice. Nc4 forks the K+Q, whereas Nd3 places the N in capturing range of more pieces, which seems more flashy!|
|Sep-03-15|| ||framsey: I appreciate that Denis played out the mate rather than resigning. Personally I hate the practice of resigning midway through a forced mating sequence. The game will be over in a moment anyway, so why not show it on the board?|
|Sep-03-15|| ||whiteshark: <framsey> You appreciate <Peter>!|
|Sep-03-15|| ||offramp: He told Peter to kiss his tullin'.|
|Sep-03-15|| ||reticulate: I love a high-quality X-ray move! I remember a beautiful one that Fischer pulled against Bisguier during his amazing run through the 1963-64 USA championship. You can see it here:
Fischer vs Bisguier, 1963|
|Sep-03-15|| ||TheaN: I too settled for 28....Qxb2+?!, foreseeing the mate if white captures and foreseeing the win if white moves to d1. However, I did not make the connection with keeping the white king on the queen side with 28....Qa1+!|
Difficult to say where this failure of vision occurs; I guess it's tunnel vision that Qxb2+ works, and Qa1+ looks somewhat counterproductive compared to the former.
|Sep-03-15|| ||wooden nickel: <Never avoid a check, it might happen to be a checkmate! -NN>
It worked in this case well, I preferred 29... Nd3# over 29... Nc4#.
The simple capturing of the knight 26... Nxc6 wins easy too ... even a move later 27... Nxc6!|
|Sep-03-15|| ||saturn2: <wooden nickel:The simple capturing of the knight 26... Nxc6 wins easy too>
I calculated some variations (27 Bxg7, 27 Ndxb4, 27 Rxb4) and was going to consent until 27 c3 came to my mind.|
|Sep-03-15|| ||Ultra: I had 26 ...Nc4 and I believe it to be winning but not as elegant as the game's play. Either White loses its Queen or loses the game.|
|Sep-03-15|| ||patzer2: <lost in space> Thanks for the correction. I did mean 3. Nf3 instead of 3. Nge2.|
After reading through your post, I now think 3. Nge2 might be just as good as 3. Nf3. It's (i.e. 3. Nge2) quite playable, and as you say after the 5. d4 cxd4 6. Nxd4 exchange it doesn't make any difference.
Also, 3. Nge2 invites 3...e5 4. Nd5 with a nice position for White.
According to the chessgames.com opening explorer, 3. Nf3 (350 games) is far more popular than 3. Nge2 (66 games).
Yet the results are almost identical for 3. Nf3 (38.6% wins versus 33.7% losses) and 3. Nge2 (37.9% wins versus 30.3% losses).
I wonder if following previous play in the follow-up to 3. Nge2 might improve?
White's 5. d4 = here is the only game in which it appears in the chessgames.com opening explorer (OE).
Previously played was 5. Bg2 with the idea of King side castling, as in F Vallejo Pons vs Fressinet, 2003. Accord to the OE, of the six games played with 5. Bg2, White won 3, drew 2 and lost only one.
|Sep-03-15|| ||doubledrooks: 26...Qa2+ 27.Kc1 Qa1+ 28.Bxa1 Rxa1+ 29. Kb2 Nc4# works for me.|
|Sep-03-15|| ||dfcx: I was stumbled initially trying to play 26...Nc4 and Nd3 first, but white can just take the queen and game over for black. So the first move must be the queen and the rest is easy.|
26...Qa2+ 27.Kc1 Qa1+! 28.Bxa1 Ra1+ 29.Kb2 Nc4/Nd3#
|Sep-03-15|| ||kevin86: Wow! A Very brilliant mate!|
|Sep-03-15|| ||rozzatu: "Simple forced mating sequence". But haven't see it. I think it is a wonderful puzzle, simply extraordinary.|
|Sep-03-15|| ||PhilFeeley: This should be a game of the day. I know Svidler played the opening badly, but the final mate is a joy to see.|
|Sep-03-15|| ||thegoodanarchist: < offramp: The final position is a Good Anarchist mate.>|
You flatter me, sir. TYVM
|Sep-03-15|| ||thegoodanarchist: < JohnBoy: Too fresh to be challenging.
Exactly. As much as I would love to pat myself on the back for solving it, I just looked at this game last month-so no.
|Sep-03-15|| ||ajile: The trick that took me a while to see was the idea of Qa2+! first pushing the king to c1 and then Qa1+. The double attack at the end with Nc4+ seals the deal.|
|Sep-03-15|| ||Bubo bubo: A little déjà-vu for me today, as my newspaper's weekly chess column featured the same problem last Friday, there already with the stipulation #4.|
Black mates with 26...Qa2+ 27.Kc1 Qa1+ 28.Bxa1 Rxa1+ 29.Kb2 Nc4# Cool!
|Sep-03-15|| ||tivrfoa: And 25... ♗c6 is a nice trap. =)|
