| Sep-09-09 | | David2009: This is an amazing and most attractive game. The theme of ...Nf2+ forking the Queen and/or checkmating occurs
on no fewer than three distinct ocasions (moves 25, 33 and 37, unplayed). |
|
| Sep-09-09 | | ruzon: Sad to say I did not consider 35...♕g4. I did consider (among all checks, captures, and threats) 35...♘c1, which tries to deflect the Queen but fails. |

| Sep-09-09 | | BOSTER: The studing today's position I have made a small conclusion.
This is no a secret that all pieces(and pawns) create the lines of force. Maybe, this is only maybe,(honestly, I have never read about this crazy idea), sometimes the interaction of such lines creates a blind spot-a space ( for ex. one square) which is unvisible for us. Can I explain this? My answer-is No. G4 square looks like a blind spot. |
|
| Sep-09-09 | | MaczynskiPratten: Did not get this :-( A good puzzle though. Looks like knight fork week. I was looking for forcing moves but did not realise Qg4 was forcing because Rf1+ only seemed to get back a R for a Q - missed the fact it had set up a knight fork from scratch! |
|
| Sep-09-09 | | dzechiel: <<Archswindler:>Also, why can't the puzzles where black is to move have the board flipped?> I have two books in my chess library that have the black pieces at the bottom of the diagram when black is the victor. All I can say is that it is disconcerting to look at a diagram from a completed game and not have white moving up the board. (I can already hear a number of people asking me how I know if the game is complete, and I don't really have a good answer for that. But when I play online I do like to have my pieces moving up the board [perhaps it's because <I> started the game and my frame of reference has been fixed from the beginning]). But, when presented with a static position from a game I didn't play, I always want to have white at the bottom moving up. (One of the books mentioned above was by Andy Soltis, a favorite chess author of mine. I wrote to ask about the upside-down diagrams, and while he has written back on other topics, I received no reply on this one. I suspect the he had no input on the diagrams, but I suppose it could have been his decision). I would be interested in an informal poll on this issue. You can post your thoughts in my forum if you have passionate feelings on this issue, one way or the other. |

| Sep-09-09 | | Athamas: Hmm it appears you are right <al wazir>. I thought the passed e-pawn would give black a harder time but it seems black wins easily after trading down. |
|
| Sep-09-09 | | ZUGZWANG67: Obviously, the BQ is the defender to get rid of. I found 35. ...Qg4, because either 36.Qxg4 Rxf1+ 37.Bg1 Nf2+, or 36.Qd1 Qxd1 37.Rxd1 Nf2 + wins a R. A little more complicated then expected, tough. Time to check (GULP!)
-----
Yes! :) |
|
| Sep-09-09 | | ZUGZWANG67: To be honest, I struggled a bit on it, as 35. ...Qg4 was not quite obvious until I really realised that B had to get rid of the WQ to make the mate threat pay. |

 | | Jimfromprovidence: <wals> <20. g4 ?? <blunder> allows the opponent back into the game (20. Qd2 and White hangs on)> Thought this was the losing move. Did not see 20 Qd2 but instead 20 g3.
click for larger viewThis move seems to keep white out of trouble as well. |
|
| Sep-09-09 | | zb2cr: Rotgut. I missed this one badly, never even considered the passive offered Queen sacrifice on g4. |
|
| Sep-09-09 | | FlashinthePan: My 1st hunch was 35...Qg4 for the deviation, but it took me some time to validate it, because I first thought Rxf1 was mate, and then saw Bg1 covering the check for White. So I ruled out Qg4 for some time and embarked on analysing Bxh4, to no avail, of course. Failing to see a better move, I then resumed analysing Qg4 and at last found Black's 36...Nf2, which made the win obvious... but I'd lost 10 minutes in the process. |
|
| Sep-09-09 | | WhiteRook48: missed it |
|
| Sep-09-09 | | ku0826: I could pick-up Black Queen in any moves. But could't find out Qg4.
It's deep thought tactical move. |
|
| Sep-09-09 | | Summerfruit: Material is even.
35...Qg4!
a) 36.Qxg4 Rxf1+ 37.Bg1 Nf2+ 38.Kh2 Nxg4+ 39.Kh1 (Kg3/Kh3 Rxg1 40.Kxg4 Rxg2+): Black is a rook up b) 36.Rf2 Rxf2 37.Qxg4 38.Rf1+: transposes to a)
c) 36.Re1 Nf2+ 37.Kg1 Nh3+ 38.Kh1 Qxe2 39.Rxe2 Rf1+ 40.Bg1 Nxg1 (41...Nf3# is threatened as well as 41...Nxe2) 41.Ne3 Nxe2 42.Nxf1: Black is a bishop up d) 36.Qd1 Qxd1+ 37.Rxd1 Nf2+ 38.Bg1 Nxd1: Black is a rook up |
|
| Sep-09-09 | | Summerfruit: I missed the line:
e) 36.Rxf8 Qxe2 38.Re7+ Kg8 39.Rxe7 Nf2+ 40.Kg1 Nh3+ 41.Kh1 Qf1+ 42.Bg1 Qxg1# |

|
| Sep-10-09 | | gofer: 35 ... Qg4
The following needs to be avoided...
36 Qxg4 Rxf1+
37 Bg1 Nf2+
38 Kh2 Nxg4+ winning
But if the queen moves then Rxf1# and if the queen
doesn't move then it needs to be supported
36 Rf2 allows Nxf2+
36 Rxf8 allows Qxe2
36 Nf4 allows Rxf4
So really 36 Re1 is forced.
36 Re1 Nf2+
37 Kg1 Nh3+
38 Kh1 Qxe2
39 Rxe2 Rf1+
40 Bg1 Nxg1 (threatening Nf3#)
41 Ne3 Nxe2+
42 Nxf1 Nxd4 winning easily
Time to check... |

| Sep-10-09 | | Once: Dang! Missed all the fun. A late day at the office combined with England vs Croatia (5-1 !!!!) meant no chess yesterday. And in the few moments I allowed myself to peak at the position, I came nowhere near 35...Qg4. Respect to all those who genuinely found it from the diagram. Why is it such a hard move to spot? I'll do my usual and offer some home-spun theories: 1. Backwards moves are hard to spot. Most attacks involve pieces moving forwards - leaping into the attack from a defensive position. This is not the first time that we have struggled to find a retreating move, either as an attacking or defensive motif. It is more usually a bishop retreat that we find difficult. 2. Moves that are not checks or captures are harder to find. Our conditioning is to attack with "moves that smite" (Purdy). 3. We generally attack by bringing up more reserves. It is unusual to move an already well-positioned piece. In today's starting position, I wanted to do something with the Be7, but didn't think to move the apparently wonderfully placed black queen. I can't recall which chess writer described this as "inviting every one to the party". 4. We are instinctively cautious about leaving two or more pieces en prise. With Rxf8 hanging in the air, it seems foolhardy to allow Qxg4 as well. 5. This is an occasion where the dictum "examine every check and capture" doesn't work, as the winning move is neither a check nor a capture! Instead, we need to find this one on general principles - ie look for a way to deflect the white queen from the defence of the Rf1. 6. The killer follow-up is the knight fork of h1 and g4. But this is hard to spot from the starting position as g4 is an empty square. Much easier to spot knight forks if both target squares are occupied. Incidentally, Fritz finds an alternative solution. Whilst 35...Qg4 is certainly best (-5.2), black can also exchange rooks to get a very comfortable edge. A pragmatic solution would have been 35...Rxf1 36. Qxf1 Kg7 
click for larger viewFritzie says -1.5. Not a clear win by any means, but an easy position to play as black. |
