 | | tpstar: The final position is a good example of a terminal pin, where the pinned piece can't move due to mate (46. Qxf3 Rxh2#). It also counts as a cross-pin since the Qg2 is the center of the action. Unfortunately, this level game turned on a blunder (45. Qg2?? Re2 0-1); Fritz 7 gives 45. Rg2 Re3 46. hg =, along with 42. Rxg3?? Rd1+ 43. Kg2 R1d2  . After 45. Rg2 note 45 ... gh? 46. Qxh6# but otherwise this ending should be drawn.Clever strategy to play the Wormald Attack against AAA since it was one of his specialties. |
|
| Mar-22-10 | | asianwarrior: its 45...Re2 and after that,its mate in three. |
|
| Mar-22-10 | | Formula7: Got it. 45...Re2 and now:
A) 46.Qxf3 Rxh2#
B) 46.b5 Rxg2 47.Rxg2 (47.hxg3 Ra2+ 48.Rg2 Qxg2#) Qf1+ 48.Rg1 g2# C) 46.h3 Rxg2 47.Rxg2 (any other rook move loses to Rh2+ 48.Kg1 Qg2# and if 47.h4/b5 then Rh2#) Qf1+ 48.Rg1 Qxh3# D) 46.h4 is the same as line C
E) Any rook move besides 46.Rxg2-46...Qxg2# |

 | | OBIT: Pretty horrifying mistake by Alapin on the previous move. Only two legal moves, and he played 45. Qg2?? |
|
| Mar-22-10 | | patzer2: As <tpstar> noted earlier in 2006, today's Monday puzzle solution utilizes a pin to facilitate a mating attack with 45...Re2! Depending on White's reply, it's mate-in-one, mate-in-two or mate-in-three. Mate-in-one occurs after 45...Re2! 46. Qxf3 Rxh2#. Mate-in-two happens after 45...Re2! 46. hxg3 Qh5+ 47. Qh3 Qxh3#. A clever mate-in-three possibility is 45...Re2! 46. h4 Qe4! 47. h5 Qh4+ 48. Qh3 Qxh3#. P.S.: Also as <tpstar> observes, 45. Rg2 = (instead of 45. Qg2??) would have held the draw. |
|
| Mar-22-10 | | zooter: This took me a min to see, but was worth it as the killer move is too good 45...Re2 wins as 46.Qxf3 Rxh2#
There is no good defence for white after Re2. Time to check |
|
| Mar-22-10 | | dzechiel: Black to move (45...?). Black is up a pawn. "Very Easy." It looks like Alapin has put up a lot of resistance in this game, but by now black's position is overpowering. Alekhine must have decided it was time to end the game suddenly, when he played 45...Re2!
This move threatens the white queen with capture, and the pin ensures that the queen has but one way to escape... 46 Qxf3
but that does allow
46...Rxh2#
I'm guessing in the actual game that Alapin resigned immediately, but those were different times when is was considered gentlemanly to allow your opponent to effect checkmate. It's time to check and see how the game actually ended. |
|
| Mar-22-10 | | zb2cr: 45. ... Re2 is the move. See the very fine comments by <Formula7>, <patzer2>, <zooter>, and <dzechiel>. |
|
| Mar-22-10 | | lost in space: 45...Re2 and there is no defence.
46. Qxf3 Rxh2#. Other white moves are losing the queen. I love Mondays |
|
| Mar-22-10 | | Train: 45... Re2 is more than that, lost in space. It's a forced checkmate, e.g. 46. h4 Rxg2 47. Rxg2 Qf1+ 48. Rg1 Qh3 mate. |
|
| Mar-22-10 | | lost in space: yeaahhh, need to train my brain. |
|
| Mar-22-10 | | Gilmoy: Alekhine plays <34.e4 35.e3> again!! |
|
| Mar-22-10 | | TheaN: Monday 22 March
<42....?>
Target: 0:40;000
Taken: pretty much 40s :)
Material: Black up, ♙
Candidates: Qxg2†, gxh2... <[Re2]> -ML-
This one took me while, taken it's a Monday. There is a Queen sac here, but it is not very clear ^^. Black has to attack the Queen another time whom is pinned. <42....Re2!> and if White captures the undefended head piece: <43.Qxf3 Rxh2‡ 0-1> Black mates. The best alternative hxg3 meets Rxg2 and Black still has to play out Queen vs Rook (Black lost his +P for the Q/R exchange), but this should be very easy. Time to check. |
|
| Mar-22-10 | | Once: Cute. It's one of those positions where the best way to defend against a threat is to ignore it. |
|
| Mar-22-10 | | TheBish: Alapin vs Alekhine, 1914 Black to play (45...?) "Very Easy"
This is indeed very easy, either by seeing the pattern right away (which I did) or by thinking that the king is more valuable than the queen, and taking it from there. 45...Re2! 46. Qxf3 (else White loses material) Rxh2#. I'm going to guess that Alapin resigned after 45...Re2!. |
|
| Mar-22-10 | | backrank: One of the very rare 'very easy' puzzles which are very nice at the same time ;) Got it in a few seconds, but I really wonder if I had noticed this blow if the position would have arisen in one of my own games ... |
|
| Mar-22-10 | | agb2002: Black is a pawn ahead. White threatens 46.Qxf3 and 46.hxg3 (Black would then have perpetual check at least by playing Qd1, Qf3, Qh5). The white king doesn't have a legal move which suggests the possibility of creating mate chances by incorporating the rook into attack. The quickest way is 45... Re2: A) 46.Qxf3 Rxh2#.
B) 46.hxg3 Qh5+ and mate next move.
C) 46.h3 Rxg2 47.Rxg2 (47.Ra1 Rh2+ 48.Kg1 Rh1#) Qf1+ 48.Rg1 Qxh3#. D) 46.b5 Rxg2 47.Rxg2 Qf1+ 48.Rg1 g2#.
The position looks like a mate-in-four composition. |
|
| Mar-22-10 | | whiteshark: Gah - it's Monday again - already! How could this happen? |
|
| Mar-22-10 | | gofer: 45 ... Re2
Now white can resign, but as its a forced mate and were are looking back at a game from many many years ago, maybe it was played out... 46 Qxf3 Rxh2#
46 R anywhere Qxg2#
White only has two options
46 h3 Rxg2 47 Rxg2 Qf1+ 48 Rg1 Qxh3#
46 h4 Rxg2 47 Rxg2 Qf1+ 48 Rg1 Qh3#
Time to check... |

| | tarek1: got it in less than 30 sec :)
45...Re2 46.QxQ Rxh2# |
|
| Mar-22-10 | | wordfunph: 45...Re2 was quite obvious |
|
| Mar-22-10 | | stacase: White's Queen is pinned against the King, and after 45...Re2 she's pinned against 46...Rh2# So, she's toast! |

|
| Mar-22-10 | | A Karpov Fan: got it |
|
| Mar-22-10 | | gus inn: <whiteshark> One of the reasons for being monday today is the fact that it was sunday yesterday ;)
but time flies-or whatever happens |
