|Feb-07-13|| ||Tolya Siberia: For Avidfan & Chessgames : Correction, Black Player is NOT Ruben Gunawan, but RONNY Gunawan. Yes, Ruben Gunawan (IGM) has died on 38 years old at 2005, but Ronny Gunawan (IM) is still alive & active playing chess until now.|
|Feb-07-13|| ||widjaja70: On move 20, instead of 20. Rd1 white should have played 20. f3. I think it is safer, while preparing for 21. Qh4. The text is a fatal blunder.|
|Feb-07-13|| ||Oxspawn: My psychic core is out of harmony with the 64-bit chequered cosmos. I see a huge variety of potential moves for black ("whoooo"), all of them exciting and most them losing in a heartbeat. It looks like the first move should be a check since otherwise white mates on h7 ("Duh"). |
22……...Ne2+ inspires me as it deflects the bishop and opens the d file to queen and rook (waves hands above board in a knowing manner), but after 23. Bxe2, I am blinded by the defensive cohesion of white's position.
I feel a combination of crashing rooks, crafty knights and swivelling queens at the ends of my fingers; I see the dismay of the white pieces as black mates on d1, f1 and h2 more or less simultaneously; unfortunately the neural path from psychic fingers to analogue brain remains blocked. No time to linger, I post an honest failure, pour another cup of coffee and play out the game. Instant calmer.
|Feb-07-13|| ||lost in space: <Not too difficult due to the forcing nature of the moves>|
True. Locking back after having the solution it is not difficult, but for me it was not solubale with just a look; It took me a few minutes and accurate calculations to find it.
|Feb-07-13|| ||Oxspawn: Nobody told me the queen could move sideways!|
|Feb-07-13|| ||goodevans: <Oxspawn: Nobody told me the queen could move sideways!> Nicely put. Yes, I missed 23...Qb6+ too.|
Shame Ljubojevic didn't resign after 25...Nf2+, then I'd have been able to add this to my "miniatures" collection. I guess he was hoping for Gunawan to blunder with 26...Rxf2?
|Feb-07-13|| ||kelu: kelu: In the variation of the game : isn't 26.Kg1 a draw ? (taking Q is not possible because white R threaten mate and black smouth mate is not possible because of the Q)|
|Feb-07-13|| ||Abdel Irada: <kelu>: Look at variation (2)(a.5) in my solution post. In the game line, as in that variation, Black simply picks off the rook on d1 with discovered check, winning easily.|
My variation inserts the moves 24. Bd4, R8xd4; otherwise the lines are identical.

Can not agree more!.
21.f3 would also had prevented ingress of Knight to g4 which proved to be fatally dangerous.
|Feb-07-13|| ||ZZpatzer: <SpikyYo: What if 18.Bxd4? I can't see how wrong it could be for white after that.>|
It seems 18....Bxh2+ 19. ...Qxd4 set up many attacking possibilities that would prove fatal for White.
|Feb-07-13|| ||mistreaver: Thursday. Black to play. Medium. 22...?
My solutions comes a bit late in the day. White threatens mate in one, and that
narrows a the choice a bit (since i don't really think that 'quiet' moves are good here).
So, let's look at all the forcing moves black has at his disposal. It is obvious
that he has to move either rook, or knight, and h2 is also weak.
I quite like the following move:
It is a multi purpose sacrifice, first is to divert the white bishop from hiting f7,
second is clearance.
white can't really decline the sacrifice with Kh1 since after Nf2+ he loses his queen.
Now there is no mate threat and black has to consider most accurate move order.
with the aforementioned threat of taking the queen
24 Bd4 Rdxd4
25 Rxd4 Qxd4+
Ok, i am quite tired now, so i will stop my analysis and check what happened.
Okay, i didn't mention that after Kh1 Rxd1 and Nf2 wins, but i think that is elementary, and that my line contains the last practical chance, should black play 24... Rfxd4 then after 25 Rxd4 Qxd4+ there is no immediate end (altough it is probably decisive advantage for black).
I think i can rightfully claim full point for today, making it 4/4 this week.
|Feb-07-13|| ||agb2002: Black has two knights and two pawns for the bishop pair.|
White threatens 23.Qxh7#.
Black can counterattack with 22... Ne2+:
A) 23.Bxe2 Qb6+
A.1) 24.Bd4 Rdxd4 25.Kh1 (25.Qd8+ Rxd8+) 25... Rxd1 26.Rxd1 Nf2+ 27.Qxf2 (27.Kg1 Nxd1+ - +) 27... Qxf2 28.Rd8+ Rf8 - +.
A.2) 24.Kh1 Rxd1 25.Rxd1 (25.Bxd1 Rxf1#) 25... Nf2+ 26.Qxf2 (26.Kg1 Nxd1+ - +) 26... Qxf2 27.Rd8+ Rf8 - +.
A.3) 24.Rf2 Rxd1+ 25.Bxd1 Rxf2 26.Qd8+ Rf8+ - +.
A.4) 24.Qf2 Qxf2 (24... Nxf2 25.Rxd8#; 24... Rxf2 25.Rxd8+ Rf8+ 26.Bd4) 25.Rxf2 Rxd1+ 26.Bxd1 Nxf2 - +.
B) 23.Kh1 Nf2+
B.1) 24.Rxf2 Qxd1+ 25.Bf1 (25.Rf1 Q(R)xf1+ 26.Bxf1 R(Q)xf1#) 25... Qxf1+ 26.Rxf1 Rxf1#.
B.2) 24.Qxf2 Rxf2 25.Rxd6 (25.Rxf2 Qxd1 26.Bf1 (26.Rf1 Qxe2 - +) 26... Kg8 - +.
|Feb-07-13|| ||PawnSac: < Abdel Irada: I think Ljubojevic had already been outplayed before move 22. By then, it was merely a matter of Black realizing his advantages. >|
14.Ne5 seems anti-thematic (Strategically the white king knight is a key piece which keeps e5 and g5 under guard). More sensible is 14.Re1. But 15.Nxd7 really appears to be a lemon. White trades off his strong knight for blacks troublesome bishop. This also pulls the queen on to the d file and sets up the discovery Bxh2+, but apparently white overlooked this, and the consequential 17. ..Nxd4, afterwhich white's game is already looking dubious.
14.Ne5 was apparently motivated by the concern for ...Qh5 but white has play with Nf1-g3.
|Feb-07-13|| ||TheTamale: Nice combo. I wish this site had a "favorite games" tag feature so I could mark a game for additional review... kind of like the "favorite" feature on YouTube.|
|Feb-08-13|| ||stst: Quite a mysterious game.
Thought it should start with
22......Ne2+ to divert the immediate kill of Qxh7#
Then IF (A)24.KxR Ne3+ forks for R, no good.
IF (B)24.BxR then obviously QxR, no good either.
So (C)24.RxR Ne3, 25.Rf2 Rf8, 26.RxR QxR .... does not lead to a clear-cut soln.
May have missed something in between....
OR, the starting point is totally different, e.g. Nge3 to fork the Rs...
|Feb-08-13|| ||UnsoundHero: After 22...Ne2+ 23 Bxe2 Qb6+ 24 Bd4, Black should recapture with his d8 rook, 24...Rdxd4, to see if White gets an adrenaline rush, and plays 25 Qd8+, hoping for back-rank mate. Play would continue 25 Qd8+ Rxd8+. If White then tries to play Rxd8, Black should remind him to take care of the threat to his own K on g1 first.|
|Feb-08-13|| ||stst: The game's 24.Kh1 allows for the easy finish of Ne2+ forks.
In between Bd4 intercept would make it much more difficult for Black.|
|Feb-08-13|| ||patzer2: The Thursday Feb 7, 2013 puzzle solution of 22...Ne2+!! initiates a clearance sham sacrifice to open up a decisive attack on the exposed Queen and weakened King position after 23. Bxe2 Qb6+! . |
However, the moves that led up to this position IMO make this an interesting game worthy of a deeper look. So here's my take on the game, using Fritz 12 and the chessgames.com Opening Explorer:
<1.e4 e6 2.d4 d5 3.Nd2>
White chooses the Tarrasch variation of the French Defense, which Karpov helped to popularize with his success with it in the 1970s and early 1980s.
Black picks the solid if somewhat cramped Guimard Variation, which seeks to exchange off the White e-pawn with the ...f6 break soon to follow. However, it appears to do so at the cost of conceding White a small positional advantage. More often played at master level is 3...c5 as in Kasparov vs Anand, 1991.
<4.Ngf3 Nf6 5.e5 Nd7 6.Be2 f6 7.exf6 Nxf6 8.O-O Bd6 9.c4 O-O 10.a3>
Perhaps better here is 10. c5 which has a record of six wins and no loses in our opening explorer. Two of those wins went 10. c5 Bf5 11. Bf5 = to as in Short vs Vaganian, 1985 and D Reinderman vs I Rogers, 1996. Though Fritz 12 says the position is even after 10. c5 Bf5 11. Bf5 Bd7 =, I'd think White's spacial advantage after 10. c5 gives a strong initiative, which could account for its success in practice.
<10...Kh8 11.b4 a6 12.Bb2 Bd7 13.Bd3 Qe8 14.Ne5 dxc4 15.Nxd7 Qxd7 16.Nxc4 Rad8 17.Qe2?>
Up until now White had a positional advantage, but this slight error allows Black to steal the initiative. Better is 17. Qf3! b5 (not 17... Nxd4? 18. Bxd4 Bxh2+ 19. Kxh2 Qxd4 20. Be2 ) 18. Nxd6 Qxd6 19. Rad1 e5 (19... Nxd4 20. Bxd4 Qxd4 21. Bxb5 Qb6 22. Rxd8 Rxd8 23. Bc4 ) 20. dxe5 Nxe5 21. Bxe5 Qxe5 22. Rfe1 Qb2 23. Bf1 , when White has a lasting advantage going into the endgame.
<17... Nxd4! 18. Qe1>
Not 18. Bxd4? Bxh2+ 19. Kxh2 Qxd4 20. Ne5 (20. Bc2? Qh4+ 21. Kg1 Ng4 ) (20. Kg1 Qxd3 ) 20... Qxe5+ 21. Qxe5 Ng4+ 22. Kg1 Nxe5 .
<18... b5 19. Nxd6 Qxd6 20. Rd1?>
Though not so obvious, this is is White's decisive mistake. Instead, 20. Qe3! Nf5 21. Bxf5 exf5 22. Be5 Qe7 23. Rfe1 Ng4 24. Qf4 Nxe5 25. Rxe5
Qd7 26. Rc1 h6 27. g3 = to gives White good drawing chances.
<20... Ng4! 21. f4 Rxf4 22. Qh4!?>
Perhaps realizing he's losing after 20. Rd1? Ng4!, White tries to complicate and give Black a chance to go wrong with 22. Qh4!?. However, Black's strong reply solves the puzzle and ends all hope of a swindle.
<22... Ne2+ !! 23. Bxe2>
This winning clearance moves, opens up both a key diagonal and the d-file for a winning attack on White's weak King and exposed Queen.
If 23. Kh1, then 23...Nf2+ 24. Qxf2 Rxf2 25. Rxf2 Nf4 26. Rf3 Nxd3 27. Rfxd3 Qxd3 28. Rxd3 Rxd3 wins easily.
<23... Qb6+! 24. Kh1>
If 24. Rf2 Rxd1+, then 25. Bxd1 Rxf2! (also winning is 25... Qxf2+ 26. Qxf2 Nxf2 ) 26. Bxg7+ (26. Qd8+ Rf8+! 27. Qd4 Rd8 ) 26... Kxg7 27.
Qxg4+ Kf8 28. h3 Rf4+ decides.
If 24. Qf2 Rxd1! (not 24... Rxf2?? 25. Rxd8+ Rf8+ 26. Bd4! Rxd8 27. Bxb6 cxb6 28. Bxg4 ; but an alternative win is 24... Qxf2+ 25. Rxf2 Rxd1+ 26. Bxd1 Nxf2 27. Be2 Ng4 ), then 25. Qxb6 Rfxf1+ 26. Bxf1 cxb6 scores the full point.
Not 24...Nf2+?? 25. Qxf2! Rxd1 26. Qxf4 Rxf1+ 27. Qxf1 .
<25. Rxd1 Nf2+ 26. Qxf2>
If 26. Kg1, then 26...Nxd1+ 27. Kh1 Nf2+ 28. Qxf2 Rxf2 .
<26... Qxf2 0-1>
