|Mar-28-11|| ||TuxedoKnight: if you can't wait to the real puzzles like the yesterday's...|
|Mar-28-11|| ||kevin86: What a problem! White sacs the queen to mate with the pawn on the seventh!|
|Mar-28-11|| ||YouRang: It took me a minute, but got it. The key point is that black's king is immobilized by the rook and knight, which means that any check that can't be stopped by blocking or by capture is mate.|
So, just looking at checks, one must eventually find 46.Qe7+! (for some reason it didn't seem intuitive for me).
Black of course can stop *that* check (with capture: 46...Rxe8), but not the next one: 47.dxe8 check and mate.
|Mar-28-11|| ||HolyAvatar: <Patriot: This took me several minutes as there seemed to be a lot of possibilities.|
I went with 46.Nd7+ since that's the first forced mate I saw. 46...Bxd7 (46...Kg8 47.Qh8#) 47.Qh8+ Qg8 48.Qf6+ Qf7 49.Qxf7# -- good enough.
But this suggests that I'm avoiding "losing the queen". Because the quickest, most forcing move is 46.Qe7+ Rxe7 (forced) 47.dxe7#. If there's a lesson to be learned, it is whenever there are multiple checks to consider, first look at the check that leaves fewer options (or no options) for the other player.
It would be a bigger mistake to find the forced mate, starting with 46.Nd7+, in a game and continue searching for a "quicker" mate.>
This is exactly my thought process
|Mar-28-11|| ||eblunt: The unspectacular looking d7 also wins quickly as well.|
|Mar-28-11|| ||BOSTER: It sounds maybe strange,but very often M&T <CG> puzzles (and their games) are more effective for understanding chess than S&S puzzles.
I don't know how and under what circumstance ( more exactly the rook on the seventh and knight on f6), but this position reminds the drawish mechanism.
I'd like you with Nimzowitsch's help to show this position with white to play.

|Mar-28-11|| ||stst: 46.Qe7+ RxQ (only defense)
|Mar-28-11|| ||scormus: Neat coup de grace.
I ever heard of the West Indian Defense, didnt think there was one. I know Black's West Indian Attack was once extremely dangerous, but the last 10 years or so its considered busted.
|Mar-28-11|| ||patzer2: patzer2: For today's Monday puzzle solution, it's an unusual mate-in-two combination with 46. Qe7+! Rxe7 47. dxe7#|
The fact that it was Monday and so many of our puzzles at the start of the week begin with a sham Queen sacrifice to force mate made it easy. OTB I might have taken longer trying to find the mate-in-four after 46. Nd7+ Bxd7 48. Qh8+ Qg8 49. Qf6+ Qf7 50. Qxf7#.
P.S.: Black had the game won and simply missed too many opportunities to simplify to a won endgame. The decisive mistake was 38...Qe6? Instead, 38...Rxe5! 39. Nxe5 Qe6! 40. d7 Bxd7 would have allowed Black to win easily.
|Mar-28-11|| ||MaxxLange: The mate in 4 you see is stronger than the mate in 2 that you don't see, I guess|
|Mar-28-11|| ||Bodul: I like 46.Nd7+ Bxd7 47.Qh8+ Qg8 48. Qf6+|
|Mar-28-11|| ||benveniste: Had this not been a Monday, I would have found ♘d7+ or d7. But since it was a Monday, I looked first at ♕xe8+ and then found ♕e7+.|
|Mar-28-11|| ||Penguincw: Oh gosh.It took me 20 seconds to solve a puzzle from a game I just saw a few weeks ago.|

|Mar-28-11|| ||morfishine: <sevenseaman> I 'searched kbitz' for your name but couldn't find your comment. March 1, 2011 falls between page 16 - 17 of your 114 pages so far. |
Perhaps, you meant a different date?
Why not become a full member? Then you can play in the inner-team game. We are only on turn 2. :) Morf
|Mar-28-11|| ||BOSTER: I really doubt that such players, who so easy sacr. Monday smb. else's queen in the puzzle mood, even touch their own queen playing OTB.|
|Mar-28-11|| ||gazzawhite: <morfishine> He may be referring to the comment on page 1 of this game (2nd comment).|
|Mar-28-11|| ||Patriot: <<BOSTER>: I really doubt that such players, who so easy sacr. Monday smb. else's queen in the puzzle mood, even touch their own queen playing OTB.>|
I totally agree. Seeing the queen sacrifice because "It's queen sac Monday" is not going to make anyone a better player. It can be a clue to the solution but I avoid this logic because that is useless knowledge OTB.
|Mar-28-11|| ||morfishine: <gazzawhite> Thanks, I didn't realize posts to this game would show up on the daily puzzle. Appreciate it. Morf|
|Mar-28-11|| ||MountainMatt: As more than a few others have pointed out, this one seems awfully tricky for Monday. It isn't, actually, but it seems so! Somehow it was all too easy for me to, at first and second glance, overlook the power of the d6 pawn. Which simply means, I'm still a patzer!|
|Mar-28-11|| ||ahubers: Didn't see this one.
But I did see that 46. Nd7+ bxd7 47. Qh8+ Qg8 48. Qf6+ Qf7 49. Rf8# is forced mate (or 49. Qxf7#, take your pick). So I guess I would have won this game were I playing it, just not quick enough.
|Mar-28-11|| ||ZUGZWANG67: It's mate in 2 here: 46.Qe7+ Rxe7 47. dxe7 mate.|
|Mar-28-11|| ||Lennonfan: There's about 5 ways to do this,but Qe7+,rook forced to take..dxe7#....|
|Mar-28-11|| ||Blunderdome: So many appealing options, it took me a while to find Qe7+|
|Aug-27-14|| ||SpiritedReposte: What a forced checkmate.|
