|Oct-04-04|| ||Rowson: This is truely a great game! I love the way Chigorin Menovers his night to gain control of the light squares in the center. Look at the squence of night moves starting with 38...Nc7 to be honest i would have excepted a draw in such a position. |
|Dec-29-04|| ||JohnBoy: White clearly had no idea what was coming his way. Chigorin had a better position, but not the crunching breakthrough that actually occurred. As of move 40, black should not have won this game. |
|Apr-18-05|| ||Milo: Chigorin seems pretty good at defense. 25.h5 looks gratuitous though. |
|May-12-09|| ||johnlspouge: Tuesday (Easy):
Reggio vs Chigorin, 1901 (74...?)
Black to play and win.
Material: N for B. The White Kf1 has 2 legal moves. The Black Q could mate at h1, so the White Qf3 has an absolute burden. The Black Rg4 supports a check Ne4-g3+. The Black Kg8 is secured from all checks.
): Qh3+, Rxf4
(1) 75.gxf4 Qxf3+ winning Q for R
(2) 75.Qxf4 Qh1#
(3) 75.else Rxf3+ winning at least Q for R
|May-12-09|| ||dzechiel: Black to move (74...?). Material even. "Easy."
It appears that both sides have been jockeying for position for some time now (it's move 74!). But if this one is easy, it looks like white must have finally made a mistake.
Please note: I finished all of the analysis below the "=====" (including the note about hoping I didn't overlook something simple) and was just about the post, when I decided to take one last look at the position. That's when
fairly jumped off the screen at me. So simple, but I didn't see it until I attempted to consider unusual moves. I decided to leave all my previous analysis just for fun.
Time to check
This is not as "Easy" as we are led to belive. Not only are there a large number of candidate moves, the winning combination is a little involved. I think the key move is
White has three legal replies:
- 75 Rg2
- 75 Qg2
- 75 Kg1
Let's deal with 'em in order...
75 Rg2 Rxg3
White has two ways to capture
76 Bxg3 Nd2+ and 77...Nxf3, or
76 Qxg3+ Nxg3+ 77 Bxg3
Both of these lines give black queen and pawn for rook and knight.
75 Qg2 Rxg3
picking up a pawn. If white tries
76 Bxg3 Nxg3+ 77 Kg1 Nxe2+ 78 Kf2 Qxg2+ 79 Kxg2 and black is up a piece.
75 Kg1 Nxg3
netting a pawn for black (76 Rg2 Qh1+ 77 Kf2 Ne4+ and white will lose a rook as well).
This all seems very involved for a Tuesday position. I sure hope I didn't overlook something very simple.
|May-12-09|| ||BraveUlysses: Poor Reggio, he must have been devastated after holding Tchigorin so well and then copping this. The lesson is: beware the open h file.|

Dzechiel - you are a legend. Very many thanks for your industrious and educative contributions!
|May-12-09|| ||TheaN: Tuesday 12 May
Material: /-\ / again, in the situation the Knight is definitely better
Candidates: Rxg3, Nxg3, Qh1, Ne2, alternating, <[Rxf4]>
This seems quite much like yesterday's, although the combination is different, making it definitely more difficult to finish for us puzzle solvers.
There are many candidates here. Most of them take out a defender, but then it seems that what's remaining for Black cannot gain more material, or even the same amount, back. The move that actually works is just a plain pin and discovered attack. Well, actually, no. It IS a take-out-the-defender, but a bit different than others.
<74....Rxf4!> pinning the White Queen. Obviously, White doesn't want to lose and captures the Rook... with the Queen first, pawn next.
A: <75.Qxf4 Qh1 0-1> the take-out-the-defender principal.
B: <75.gxf4 Qxf3 > and this is the discovered attack I was talking about. Take note that this is definitely the best move as defending won't work: after Rxf4, the White Queen is suddenly attack twice from none. Not defendable, unless White can utilize a discovered defense. He can't.
Time to check.
|May-12-09|| ||zooter: I looked at this for quite a bit and had 74...Qh3+ but obviously I missed the simpler....|
74...Rxf4 which wins outright for black...I didn't find this easy as Rxf4 was never a candidate move for me...
Missing Tuesday doesn't bode well for the week, but then again there is tomorrow
|May-12-09|| ||SuperPatzer77: I completely agree with you chess folks - it is not easy as 74...Rxf4! I didn't see. |
75. gxf4 Qxf3+, 76. Bf2 Ng3+ (fork check), 77. Kg1 (77. Ke1 Qxe2#) Nxe2+, 78. Kf1 Nxf4 (White has to try to avoid being mated but he has no defense against the inevitable checkmate), 79. e6 Kf8, 80. e7+ Kxe7, 81. b5 cxb5 (mate in next move)
|May-12-09|| ||agb2002: White's queen is loose, aligned with the king along the f file and prevents ... Qh1#. These facts suggest 74... Rxf4:|
A) 75.Qxf4 Qh1#.
B) 75.gxf4 Qxf3+ (in the case White's player is very stubborn)
B.1) 76.Kg1 Qxe2 - +.
B.2) 76.Rf2 Ng3+ 77.Kg1 Qh1#.
B.3) 76.Bf2 Ng3+ 77.Kg1 (77.Ke1 Qxe2#) Qh1#.
|May-12-09|| ||remolino: ... 74. Rxf4 and wins
Reggio allowed himself to keep a terrible bishop on black squares, while his white squares where weak, and had a lost game as a result. I guess in 1901 there was no theory of good vs. bad bishops. He also opened the 'h' file but did not launch any attack there, merely opened the file for Chigorin.
|May-12-09|| ||gofer: Nice one... Rxf4 with only three options for White; |
75 Qxf4 Qh1#
75 gxf4 Qxf3
any other move and
75 ... Rxf3(+)
|May-12-09|| ||whiteshark: 74... Rxf4 wins easily.|
|May-12-09|| ||cheeseplayer: I know the game looks great to some and the peices are well organized but I must admit I suffered when I watched the game till the end.|
|May-12-09|| ||kirchhoff: After a couple of dismal weeks I told myself I would bear down and at least get Tuesday and Wednesday this week. I suceeded today. Wish me luck for tomorrow.|
|May-12-09|| ||Geronimo: It is, after all, encouraging that I made at least the same error as someone as regularly strong as dzechiel. I analyzed Qh3+ for about 3 minutes before deciding it "must be right" (sigh). This was indeed a tuesday puzzle, which does not bode well for me this week.|
|May-12-09|| ||zb2cr: I missed this one, going instead for 74. ... Qh3+ with the idea of ... Rxg3 after White interposed the Rook or Queen. But, the 74. ... Rxf4 solution that actually occurred is more forcing.|
|May-12-09|| ||eblunt: <dzechiel> Thank for your insightful (as ever) contributuion. Mainly because it made me (and I suspect quite a few others <zb2cr, Geronimo, zooter> hello) feel not quite so stupid at having missed the answer and gone for Qh3+ !!|
|May-12-09|| ||geeker: I found ...R:f4, but it took longer than usual for Tuesday, as there were quite a few candidate moves I examined first, without finding anything forcing. I only arrived at the solution after being unsatisfied with about four other candidates!|
|May-12-09|| ||dukesterdog2: With the knight in the middle of the action, it was tempting to look for a knight fork, but the d2 and g3 squares were too well protected. |
Took me a few minutes to find Rxf4 and realize that either capture by black loses.
|May-12-09|| ||krisxch: Hi.It's 74-Rf4!if 75-gf4 75-Qf3 or if -75 Qf4 75-Q-h1xx ok|
|May-12-09|| ||YetAnotherAmateur: 74 ... Rxf4 pins the queen while uncovering the attack from h5. If 75 Qxf4, Qh1#. If 75 g4, Rxf3+ 76. Kg1 or Kg2 Qxg4+ 77. Kh1 Ng3+ and mate follows in 3. Any other move results in Qxf3+.|
Although like dzechiel I was very tempted by Qh3+, it didn't look to me like a clear advantage presented itself.
|May-12-09|| ||gawain: Can't believe I solved this more quickly than my idol <dzechiel> whose postings are always so illuminating. But I did!|
I saw that 74...Qh1 would be mate if not for the white queen at f3. So I looked for a deflection. ...Rxg3 would not work, so it had to be ...Rxf4! and sure enough....
|May-12-09|| ||JG27Pyth: Argh!!! Hardest Tuesday ever!
What really annoys me is that I examined Rxf4 early, with that little tingly feeling that accompanies finding the correct move -- but for some reason I was just blind to the mate in one threat if Qxf4, and rejected it. That left LOTS OF TIME to examine the bazillion other promising moves...
LOTS OF TIME.
Sure are a lotta fork-y discover-y thing-ys there ... ... one of them has to work...
*three days later*
Okay, well, I guess I'll examine the Qh3+ ...
