|Apr-11-14|| ||DrAttitude: Great Attack!|
|Apr-11-14|| ||DrAttitude: This attack is how to work the "Maroczy Bind" (e4 & c4 vs e6/d6) that gets transformed to <e4 & c4 vs e6/c6>. Elements: 1.Queen "lift" (Qd3 to h3), 2.Bb2, 3.f5 sacrifice. 4.Rf5 sacrifice.
Powerful Bishop on e4. Incredible tactical ability. Absolutely amazing!
Excellent game by GM Hou Yifan.|
|Apr-11-14|| ||Rob Morrison: What a pretty game. If only chess could always be this easy.|
|Apr-11-14|| ||Nerwal: <If only chess could always be this easy.>|
Well, black is rarely that cooperative (in GM games, at least).
|Apr-11-14|| ||Gilmoy: After <11..Bc5+> Black's Q-side looks like a very much delayed Meran.|
And after <13.e5>, so does the K-side. Kicking the Nf6 is schoolgirl QGD.
Surely Black has sharp(er) anti-Maroczy lines. Seize the day, don't just lie there like a blobfish.
|Apr-11-14|| ||xanadu: To play Sicilian against Hou Yifan it never was a good choice...|
|Apr-12-14|| ||Strelets: Nice finish too: 24...Kh8 25.Bxf6+ Bxf6 26.Qxf6+ Kg8 27.exf7+, winning Black's queen via discovery.|
|Apr-12-14|| ||rogl: Even better is 24...Kh8 25.Bxf6+ Bxf6 27.Qxf5 with 28.Qxh7# to follow.|
|Apr-13-14|| ||ex0duz: What a game, what an attack, what a finish!
With that said, black had a horrible game, straight out of the opening it seems.
Yes, I'm a pazter compared to Nana so please forgive any mistakes in my analysis, but here i go.
I think black starts going wrong after 10 dxc6. I don't understand this move and thus i really don't like it.
Why block your own bishop behind the pawn? And also the queen on the half open c file? I know black wants to 'gain' a tempo with Rd8 after chasing the queen from the d file, but i'm also pretty sure that white wanted to move the queen anyway to the H file. Also, even before that, black again blocks his light square bishop AGAIN by playing 11.Bc5+. Now black can't even do a c5 break to free the bishop..
It can't be just me who thinks that check looks really ugly. Again, the white king probably wanted to move off that diagonal anyway to h1. Or at least white can still defend the dark squares and the knight isn't going to check on f2 anytime soon via g4 for some 'windmill-knight' discovered check tactics..
After 13.e5, i think black is in serious trouble. White should never be able to play e5 so easily, and because of the earlier 10. dxc6, e6 cannot be challenged and black could of played d6 himself stopping e5's from white.
Also, with the pawn on c6, blacks bishop no longer controls e4, which whites knight just plants itself on after playing e5.
Black then plays 17.c5 anyway(after retreating the bishop and losing the earlier tempo from the check), in order to now take the e4 knight with his LS bishop. Now after c5, blacks knight on d7 is also trapped and stuck in a horrible position and blocking the open file that the rook would have liked to be on..
And then comes 20.f5! and 21.Rxf5! That's how strong the attack is and how horrible blacks position is. Completely dominated by white, black got completely outplayed and shut down. It was like watching a GM vs an amateur..
I think even i would have done better than Nana in this game vs the world champion. Hou Yifan made it look soooooo easy, like she didn't even have to think. Black just seems to self destructed, making nearly all of whites moves pretty obvious except f5 and Rxf5(for this patzer anyway, for others i'm guessing that that's an even easier move to find right? :P).
|Apr-13-14|| ||celtrusco: Guys, after to translate the text of the post, the board go crazy ¿Why? ...Houston, we have a problem!...|
|Apr-13-14|| ||mrbasso: <exoduz> Your patzer critic is not entirely justified. After 10...Bxc6 11.Be3 black has problems as well. There are (at least) 2 games in the dabases and Hou has undoubtly prepared some improvements for white (for example Bb4 12.Rac1!?).
Bc5+ just blocks the c-pawn temporarily. She intended to go Be7,c5 but first forced the white King to h1. Why not? The white King on h1 is hardly better than on g1 here because after c5 the diagonal a7-g1 is blocked. No tactics there. The only big mistake I can see in this game was 19...b5??.
After 19...f5 white is better but it would not be easy to win this game.|
|Apr-13-14|| ||lemaire90: White to move at move 21 would make a nice Saturday or Sunday puzzle !|
|Apr-14-14|| ||HeMateMe: Very sharp; white has a mate in 4. Two Bishops working together are monsters.|
|Apr-15-14|| ||sofouuk: after 6.Nc3, Bb4 is the principled move. risking the curled up hedgehog against whites maroczy bind is always a bit dubious|
|Apr-22-14|| ||Boris Schipkov: This game with my notes http://www.chessib.com/hou-yifan-na....|
|May-03-14|| ||Gregor Samsa Mendel: It must have been very satisfying for white to pull off such an attack. Sort of the chess equivalent of Mike Tyson in his prime.|
|May-03-14|| ||al wazir: White's 21. Rxf5 was obvious. I didn't guess any of the moves that followed, black's or white's.|
|May-03-14|| ||Mating Net: I think most users will find this puzzle to be pretty straight forward for a Saturday.
All in all, a nice mating attack.|
|May-03-14|| ||morfishine: I remember this game and <21.Rxf5>. Perhaps Black improves with 21...f6|
I aslo remember Hou's great play in Tata Steel 2013 lopping off a few GM heads (on the way to a 2700+ performance rating) as well as her spirited effort vs Magnus: Yifan Hou vs Carlsen, 2013
|May-03-14|| ||gofer: As with all sacrifices, the question is not what will
happen after it has been accepted (and an easily predictable path
has been chosen), but what will happen after it has been refused.|
<21 Rxf5 ...>
The rook is immune.
21 ... gxf5?
22 Bxf5 ...
22 ... Rfd8?
23 Qxh7+ Kf8
22 ... Bh4?
23 Qxh4 Nf6?
24 exf6 Rfd8
25 Qxh7+ Kf8
So what now? We are a pawn up with the threat of Rh5
21 ... Nxe5?
21 ... Kg7?
<21 ... f6>
<22 e6 ...>
22 ... gxf5?
23 Bxf5 Rf7
<22 ... Ne5>
<23 Bxe5 fxe5>
<24 Rf7 Rxf7>
<25 exf7+ ...>
25 ... Kxg7
<25 ... Kg7>
<26 Be5 ...>
In the longterm black is dead, the open f file and protected pawn on f7 mean that
black will eventually have to trade R for B+P and that will be very difficult to
be the trade that black gets! I am wondering if <22 Rh5> might also be an option...
Hmmm, never thought of <21 ... Qb6?!>...
|May-03-14|| ||jffun1958: Rest of it ist mate in 4:
24. ... Kh8 25. Bxf6+ Bxf6 26. Qxf5 Rd1+ 27. Rxd1 any 28. Qxh7#
|May-03-14|| ||waustad: I didn't consider Qb6 either, though I did see the sac.|
|May-03-14|| ||mbvklc: I remember this game too well to get a puzzle out of this. Amazing attack nevertheless.|
|May-03-14|| ||Marmot PFL: 21 Rxf5 gf5 22 Qxf5 and the game soon ends
21...f6 is a better defense, at least I don't see a fast win. Don't see any other tries than 21 Rxf5 anyway as Be4 and e5 are both attacked.
