|Nov-09-10|| ||njchess: Nice puzzle. This game highlights a mismatch of opponents. White is outclassed here almost from the start. He recaptures a pawn with his queen but at the cost of a loss of tempo. |
7. a3? is simply a poor choice given Black's lead in development and the fact that the c-file will be opened sooner than later (meaning his queen is far from safe). This seemingly innocuous slip, together with the lost tempi due to moving his queen, represents a significant nail in the coffin. At this point, with the opening of the center imminent, White needs three moves to castle. e3 or even g3 are better.
Again, 10. Nbd2? fails to address the larger issue of White's King's safety, and actually cuts off White's bishop from the vulnerable c1 square. 11. g3 is too little too late, and, obviously, 12. Bd4? illustrates that White had no idea how vulnerable he was.
Good example of strong strategic play versus tactical play.
|Nov-09-10|| ||desiobu: 12...Nd3+
13. Qxd3 Qc1+ 14. Rxc1 Rxc1#
13. exd3 Qxc2
|Nov-09-10|| ||Patriot: 12...Nd3+ wins the queen or mates. I didn't even consider 13.Kd1 as a possibility, but it doesn't seem necessary since that would only defend the queen once while it is attacked twice. The other two possibilities are absolutely critical. 13.exd3 Qxc2 or 13.Qxd3 Qc1+ 14.Rxc1 Rxc1#.|
|Nov-09-10|| ||moex: <once> .... simply spectacular ....|
|Nov-09-10|| ||cuppajoe: I spent about ten minutes trying to figure out a way to win the Knight on c5 without allowing checkmate or losing the Queen before I noticed it was Black to play.|
|Nov-09-10|| ||Ratt Boy: Took me bloody forever. I kept looking at …Nd3+, but a mental block kept me from recognizing the obvious double threat of back-rank mate and the Q. I looked at …b4, followed up by …Ba4, with some hopes of back-ranking it; and …e5, with the idea of…what, exactly? Finally, after looking away, the obvious …Nd3+ re-emerged. Facepalm!|
|Nov-09-10|| ||howlwolf: I think after 11 . . .Qc7 12. Nb3 is white's best attempt to hold the position; the idea is to institute wholesale exchanges on c5 followed by Kd2 to keep the black rook out. I suspect black's best response is 12. ... Nfe4 and he still seems to have some pull though white retains drawing chances.|
|Nov-09-10|| ||bobfixer: Wonderful <Once> again. For when your book with games and stories?|
|Nov-09-10|| ||scormus: <Once> Brilliant!! The best yet. Reading it is my reward for doing the puzzle.|
|Nov-09-10|| ||kevin86: Easy---White is given a Hobson's choice:
He can either-capture the knight with the queen to get her out of danger,but would face a back row mate.
Or-abandon the lady.
Either way,he's lost.
|Nov-09-10|| ||patzer2: For today's Tuesday puzzle solution, 12...Nd3+! uses the discovered attack with check tactical shot to create a decisive dual threat -- a back rank mate or loss of the Queen.|
If 13 Qxd3, then 13...Qc1+ 14 Rxc1 Rxc1# is a quick back rank mate.
If 13. exd3 or 13. Kd1, then 13...Qxc2 snares the Queen with mate to soon follow.
|Nov-09-10|| ||jackpawn: It's funny how the mind works. I found this one immediately.|
|Nov-09-10|| ||randomsac: After Nd3+ white must either give up the queen or succumb to a back rank mate. A great move to uncover the battery of pieces waiting on the open c-file.|
|Nov-09-10|| ||Naugh: <Once>
That is epic. And yeah, Nd3+ was obvious. I looked for a knight fork and instead found the double attack.
|Nov-09-10|| ||dzechiel: <Jedzz: <dzechiel>, great commentary as always, but in your third line, 13. ... Qxc2# is checkmate. The white king moved off e1 for a reason, you see.>|
Right you are! Interestingly enough, when I read some of the commentary previous to my entry, I saw where <Nullifdian> also had 13...Qxc2# as mate, but I thought HE had overlooked the king's retreat to e1.
I'll put this down to a very mild case of amaurosis scacchistica.
|Nov-09-10|| ||patzer2: <Once> As a married man, you've learned the lady of the house is always right when it comes to an argument.|
In this case, <"If you hadn't gone to d4, we wouldn't be in this mess," retorted the queen.> is the comment that points out the decisive error (i.e. 12. Bd4??)
Instead, 12. Nb3 to = would have allowed White near even chances.
P.S.: Of course this sounds more like the folks at the bottom blaming each other because the guy in charge won't take responsibility for directing all their bad moves.
|Nov-09-10|| ||wals: No problem with that one.

|Nov-09-10|| ||BOSTER: Because yesterday game was more instructive and more interesting than today miniature, I want to make one move back (from your permission) and show this diagram.

This is the position in game Van Wely vs Hansen after 37...Rb2. White to play. They are in the deep defense.
Rook on g1 can not move, bishop e3 and queen have to protect f2 pawn against the mate. It would be nice if somebody could steal e5 pawn, white could play Qb8+ and Qf4,...but.
In real game white played 38.a5 (this is too optimistic) and <Domdaniel> found the improvement for black, who played 38...Kh7.
<Instead, however, black could have played 38...Be4- the same blocking mechanism actually used in the game a few moves on. This wins>.
But we are not in a hurry,and still in position on move 38, and because black plan is too easy to see,white should not play a5,but play 38.Qd4,attacking the rook on b2.
If 38...Rxb3 39.Qf4, if 38...Rb1 39.Qxd5 Qxd5 40.Rxb1 with draw.
|Nov-09-10|| ||sbevan: Ouch!|
|Nov-09-10|| ||emonys: Once, your story is amusing, but your spelling is horific use spell check in the future please|
|Nov-09-10|| ||Once: horific?|
|Nov-09-10|| ||Prelate: <Once> ought to make a collection of his posts and produce a book :)|
|Nov-09-10|| ||Arknard: Nice problem. Once I saw that it was black's turn to move, the problem was labelled 'easy', and your aware their is a decisive combination, I found it quickly (not always the case in an actual game!). Even GM's have been known to overlook simple combinations against strong opponents.|
|Nov-09-10|| ||WhiteRook48: 12...Nd3+ 4 seconds. Had this been an actual game I probably would miss it.
what was up with 12 Bd4???|
