 | | al wazir: My analysis of 24. Qa7+ Kc7 25. Nc6 Ra8 is wrong: 26. Qb6+ is answered by 26...Nxb6. But after 26. Qd4 bxa6 27. Qxc4, white still has a strong position, threatening 28. Nxe7+ and 28. Ne5+. |
|
| May-18-16 | | AlicesKnight: 24.Nc6+ looks possible - there is no K move or P capture so Rxc6; 25.Qa7+. If 25.... Kc7 then 26.Rxc6+ Kd8; 26.Qb8+ and mate to follow, while if 25....Kc8 then dxc6 forcing recapture by the P which frees the White R and gives time for Qa8+ winning the other R at least ..... let's see - close enough. Black's 19th and 20th moves amounted to a waste of time while White set up the heavy pieces. |
|
| May-18-16 | | Olsonist: What about Nb5 as an alternate solution? With the threat of the Ra8 sac/mate black has to drop his queen. |
|
| May-18-16 | | ndg2: I also opted for Nb5. Black has to give a whole queen for just a knight. |
|
| May-18-16 | | patzer2: Impressive play from a young Ray Robson in the World U-12 Championship. For an early opening improvement for Black, I prefer the popular move 7...Be7 = (0.17 @ 37 depth, Komodo 9.42) as in Nakamura vs A Giri, 2016. The strong move which gives white a decisive advantage is 19. Ra3!  (+1.97 @ 17 depth, Deep Fritz 15). |
|
| May-18-16 | | nisharaj31: Nb5 does not work as the white queen is en prise |
|
| May-18-16 | | Modulo: White to play, 24. ?
It seems like there is a mate somewhere, but since I can't find it I'll go with 24. Nc6+ Rxc6
25. Qa7+ Kc8
26. dxc6
winning the exchange while maintaining a good attack. |
|
| May-18-16 | | whiteshark: Black's final 4 ♘ moves starting with <19...Ne4> looked quite unfavourable. |
|
| May-18-16 | | morfishine: Checking-checks, that is (1) 24.Qa7+> & (2) 24.Nc6+ leaves <24.Nc6+> as the best check ***** |
|
| May-18-16 | | schachfuchs: I don't understand black's 19....Ne4 20.Qb4 Nc5 21.Bxa6.
Couldn't black get any other couterplay? |

Okay, we can play the following line as <agb2002> points out... 26 Qa8+ Kc7
27 Rxc6+ bxc6
28 Qxh8 Qg4!
...but I found defending the position a little too tricky, so instead
wanted to play...

30 Be3+ mating!
and all other ones seem to leave black a whole rook down or worse! <26 ... Qc7>

This may not be the most material gain for white, but it sets up a very clear
positional advantage that Black is doomed to fail from here on... 27 ... bxc6

| May-18-16 | | CHESSTTCAMPS: In this middle-game attacking position, white's pin of the b-pawn keys a strong attack against a weakened queen-side castled position. It seems a reasonable assumption that white has already exploited the pin by grabbing a pawn at a6, provoking a clever, but inadequate counter-attack 23... Nc4 to try to shift the pinning queen. But white holds the important cards and can cash in with: 24.Nc6+! leaving black only 2 legal moves that both lose. A. 24... Qxc6 25.Qa7+ Kc7 26.Rxc6+ Kd7 (Kd8 27.Rxc8+ Kxc8 28.Qa8+) 27.Qxb7+ is a slaughter. B. 24... Rxc6 25.Qa7+ Kc8 (Kc7 26.Rxc6+ Qxc6 [26... Kd8 27.Qa8+ forces mate] 27.dxc6 wins) 26.dxc6 Qc7 27.Qxb7+ Qxb7 28.cxb7+ Kxb7 29.Ra4 nets white an exchange plus several pawns. Time for review.... |
|
| May-18-16 | | Ayaend: <al wazir> Yes I wanted to tell you at your line is wrong but you saw it and have corrected ^^ but anyway White is clearly better. |
|
| May-18-16 | | mel gibson: The first move is easy - then it takes a lot of thought to finish the game off. |
|
| May-18-16 | | thegoodanarchist: White gave Harsha treatment to Black's king. |
|

 | | Jimfromprovidence: I had the same line as <gofer> 24 Nc6+ Rxc6+ 25 Qa7+ Kc8 26 dxc6 Qc7, but then diverged with 27 Qa8+ Qb8 28 cxb7+ Kc7.

click for larger view One response is 29...Nb6 30 Re1 (seeing 31 Rxe7). |
|
| May-18-16 | | kevin86: The crucial pin of the b-pawn will win black's queen. |
|
| May-18-16 | | dumbgai: Well, I feel stupid for going with Nb5, not noticing that white would lose the queen! |
|
May-18-16
 | | gawain: Alas! Like a few others I (suffering from chess blindness)thought 24 Nb5 would win. Oops. I liked 24... Rc7 (or Rc5) 25 Ra8+ Kxa8 26 Qa7# |
|
| May-18-16 | | YouRang: Well, I started with <24.Qa7+> (following the "monkey see check, monkey do check" principle). This gets my Q out of danger from Nc4 and forces <24.Kc7>. Now, I can kick that Nc4 with <25.b3>.

Black's only move to save his knight is <25...Ne5>, but this allows my Q to return to b6 with check, forcing the K back to b8: <26.Qb6+ Kb8>
click for larger view
This is essentially the same position we started with except my Q is out of danger, so I have time to play the killer: <27.Nb5!>, which seals off c7, thus threatening Qa7#.

Black pretty much has to trade his Q for my Nb5, which pretty much leads to an entertaining endgame (spoiled only by the likely resignation of black). So what that 24.Nc6+ is a bit faster? Wins should be savored. :-) |
|
| May-18-16 | | dumbgai: <YouRang> What about 25...Kd8, which threatens ...bxa6? |
|
| May-18-16 | | YouRang: <dumbgai: <YouRang> What about 25...Kd8, which threatens ...bxa6?> Yeah, that's probably black's best, but even so white can get the R out of danger with <26.Ra4>, which seems to force <26...Ne5>

White has a pretty tactic here:
<27.Bxc5> removes defender of c6 <27...dxe5> recaptures, but also opens the d-file... <28.Nc6+!>
click for larger view
If 28...bxc6?, then 29.dxc6 exposes the rook pin on black's Q+K. So, we play <28...Ke8 29.Nxe6> (win another P and attack Q)

Okay, maybe not a slam dunk, but white is up 2P and has a vicious attack underway with all pieces active and rangy, along with the passed Pd5. Meanwhile, black's house is on fire, his Rh8 sits there like a worthless stump, and his Be7 isn't being real helpful either. I'm not too ashamed to call it a white win. |
|
| May-18-16 | | stst: The Black K is tightly trapped, but if the White Q checks first, after Kc7, White has no follow-up threats.
So let the N go first:
24.Nc6+ RxN (if ... QxN, after Qa7+, K moves, dxQ and Black lost the Q without compensation.)
25.Qa7+ Kc7/c8
26.RxR+ Kd8
27.Qa8+ Qc8 (hopelessly delaying only one move)
28.QxQ#
see if anything is over-looked. |
|
| May-18-16 | | stst: < I had the same line as <gofer> 24 Nc6+ Rxc6+ 25 Qa7+ Kc8 26 dxc6 Qc7,...> Here,
26.dxc6 taking the Black R is too anxious, it is soft, and does not threaten anything... Much better is
26.RxR+ utilizing the Qa7 position, and forces either a K move (trying to escape,) or, a Q-intervene: Qc7 where the White R takes, winning both R & Q. |
