|Aug-15-08|| ||ravel5184: OK, maybe not a bullet game, but a blitz game at least.|
|Aug-15-08|| ||Once: The knight on c6 is attacked twice and defended twice, but it is surprisingly vulnerable. The pawn at b7 is overworked, as it cannot defend both Ra6 and Nc6.|
And if the rook wasn't there, Nxc6 forks the black queen and rook.
So let's doodle with some "mad" moves. 22. Qxb7 Bxb7 doesn't work. 22. Qxc6 and 22. Nxc6 are also non-starters. So let's try 22. Qxa6. This deflects the b7 pawn away from the defence of Nc6. And once we have exchanged knight for d8 rook, we can snatch a pawn with Bxa5.
I didn't spot 24. Nxc3 but it does not worry me in the slightest. It opens the diagonal of the g2 bishop and accelerates the doubling of the rooks on the c file. White is up by two rooks for a queen in a position with open files - and that is good enough for me.
Fritz 11 spots the combination instantly, but wants to play 22. ... Nxc3. Ends up with the same line as the game.
|Aug-15-08|| ||arnaud1959: < al wazir> I think after 27.-♕f5 white can still play 28.♖de1 to threaten mate or ♗c8. Now if 28.-♗e6 29.♖c8+. If 28.-♔f8 29.♗b4+ and if 28.-g6 (hoping for perpetual check) 29.♖e8+ ♔g7 30.♖cxc8 ♕b1+ ♖ or ♗e1.|
|Aug-15-08|| ||2ndNature: I agree with <ravel5184> - that was the easiest Friday for years.|
|Aug-15-08|| ||whiteshark: So what's the bad news?|
|Aug-15-08|| ||BlackWaive: I found the following line:
22. Qxa6 bxa6 23. Nxc6 Qd7 24. Nxd8 Qxd8 25. Bxa5
...where White has two Rooks and a Pawn for a Queen, as well as initiative on the c-file. I don't believe that there are better options for either side.
|Aug-15-08|| ||ravel5184: <2ndNature> Thank you for typing my username correctly! You are a great role model!|
|Aug-15-08|| ||Sleepyworker: I get no points since I remember this game...it was in either The Art of Attack or Think Like a Grandmaster...can't recall which one I saw it in -.-|
|Aug-15-08|| ||456: Thursday puzzle Aug-14-08 <22. ...?> Winawer vs Chigorin, 1882|
|Aug-15-08|| ||johnlspouge: Friday (Difficult): White to play and win.
Material: B for N. White has an outpost Ne5 supported by Pd4 exerting pressure on the Q-side light squares with Bg2 and Qb5. The White Rc1 and Rd1 are connected and actively placed controlling the center. Overall, the Black position (particularly Bc8 and the back rank) is cramped but relatively solid. The Black Kg8 is lightly defended. There are no obvious candidates, so on to the usual suspects: no checks, but several captures are possible. Only Bc3 requires activation.
Candidates (22.): Bxd5, Nxc6, b4, Nc4, Be1, Bxa5
Today, I had a clean miss on the candidate move.
|Aug-15-08|| ||dTal: <dzechiel> I too saw exactly that line in under a mt, but failed to see the.. NC3 line. But this works out even worse for Black in the end.|
|Aug-15-08|| ||patzer2: After 22. Qxa6, Black could try 22...Nxc3 (diagram below)
when 23. Qd3? ("saving the Queen") would be a mistake, since it allows Black to equalize with the simple 23...Nxd1=.|
Instead, after 22. Qxa6! Nxc3,

White should play 23. Rxc3! (not 23. Qd3? Nxd1=), when Black has no good alternative to 23...bxa6 (23...Nxe5 24. Qxa5 ) 24. Nxc6 Qd7 25. Nxc8 Qxd8 26. Rdc1! (transposing back to the winning game continuation).
|Aug-15-08|| ||Slurpeeman: I got it! However, it is sad that the puzzle took me so long to solve (about 5-10 minutes). In tournament conditions, I would be losing on time if I thought for THAT long|
|Aug-15-08|| ||chrisowen: Make no bones the queen sac leaves a gaping black hole for the white rook to whirligig up the board. The catalan, trust Luckin to get it excited.|
|Aug-15-08|| ||jovack: Nxc3 is bad and was never even considered by me. The position after Nx3 is like a separate monday puzzle.|
|Aug-15-08|| ||kevin86: I missed this one-white gives up the queen for two rooks-AND-a glorious attack. Later he will bag the queen back and finish a piece ahead.|
|Aug-15-08|| ||YouRang: Well, I did peek at 22.Qxa6 bxa6 23.Nxc6, but the following lines seemed complicated enough that I wasn't confident that black couldn't find a refutation of that idea.|
So instead of one really good idea, I had for two rather tame ideas:
Tame idea #1: 22.Nc4, putting extra heat on Pa5. How can black defend? I suspect he would try 22...Qc7, and then comes 23.Be1, which begins to open the c-file with pinning threats on the black knight. I threaten to open it further with 24.Ne3 with lots of heat on d5 and c6, or if 23...Na7, then 24.Qc5. I think white might just be better!
Tame idea #2: 22.Be4, and my bishop is nicely developed, containing traces of a distant kingside attack!
It's not really inspiring stuff, I know. But a lot of games are won with tame ideas. :-\
|Aug-15-08|| ||TheaN: 5/5
I have to admit that delaying Nxc3 never occured to me (it IS very weak so that might explain why), neither did the final blow Bb7!, although I do not consider that as vital for the combination as the first three moves: as 2R vs Q is usually quite an advantage anyway (I have to admit that in Blitz I prefer the Queen, but I won a two Rooks vs Queen endgame yesterday nonetheless).
<22.Qxa6!> not too hard seeing that the White Queen is quite locked up into the Black position, and this is at this point the only way to really get anywhere for White (retreating with Qb3 being drawish). I not gonna to vary too much today: if Black does not capture the Queen, White will simply win AT LEAST the exchange.
<22....bxa6 23.Nxc6> as Pb7 was its only protector, and now White continues with the Knight fork winning an exchange and thus ♗+♖+♖ vs ♗+♕ with a better position. However, Black should still watch out how to react.
<23....Qe8> this doesn't really matter, Black should just defend d8.
<24.Nxd8> now Black can vary a bit, which I did not consider tbh.
<24....Nxc3> with some analysis the wrong way to go, but it seems clear that White already gets his advantage of two pieces versus one one move later:
<25.Rxc3 Qxd8 26.Rdc1 > okay, in the puzzle I missed the forced continuation 26....Bd7 27.Bb7! with 28.Rc8!. Still, even without this tactic, White is winning after move 26, and I would've continued like this OTB: once the position is there after move 25, it's not hard to spot.
<24....Qxd8> the better alternative seeing the winning line after Nxc3, but now White can still use his ds Bishop, and do this exactly one move later.
<25.Bxa5 > immune due to 25....Qxa5? 26.Rc8† Qd8 27.Rxd8‡, and with this pawngrab White is much better, but I would not call it decisive.
|Aug-15-08|| ||sallom89: got it :O|
|Aug-15-08|| ||al wazir: <arnaud1959: I think after 27.-Qf5 white can still play 28.Rde1 to threaten mate or Bc8.> |
I tried to keep it simple and overdid it. 25...Bde6 works against 27. Rec1, but not against 28. Re1. After 28. Re1, black plays 28...g6 or h6. Then comes 29. Re8+ Kg7/Kh7 30. Rexc8 Qb1+ 31. Rc1 Qxb2 32. Bb5, and white has a winning material advantage.
|Aug-15-08|| ||Woody Wood Pusher: I can't say I am really convinced by this puzzle, it seems black could play better.|
What about 22. Qxa6, Nxc3 23. Nxc6,bxc6 24. Qxa5,Nxd1
The Master Chess (32 bit 20 MHz) evaluates this as +0.7 so white has an edge, but not a decisive advantage!
Could somebody check that line for a mistake / improvement?
|Aug-15-08|| ||Woody Wood Pusher: ah.....23.Rxc3, bxa6 24. Nxc6, Qd7 25. Nxd8, Qxd8 26. Rdc1 takes care of that.|
|Aug-15-08|| ||SpoiltVictorianChild: That was gorgeous. No way I would have ever seen that.|

 Next time ;>)
