 | | radtop: It's quite a feat to take down a player 217 points above you. Grooten did it with style. |
|
| Apr-05-17 | | ChessHigherCat: <WhiteShark> The best move is <22.Bc4!>, preparing to go to b3 to defend the king, and attacking e6 just as well as from h3. … Black is forced to play <22...d5> when we reply with <23.Bb3>." I was looking at 20. Bc4, two moves earlier. Not only does the bishop protect the white castle better on c4 than on h3 but it seems like a waste of time taking gxf7 directly, it's better to develop the attack first and leave the pawns as a threat. Black can't take the g pawn without weakening the castle anyway. |

| Apr-05-17 | | morfishine: <27...Rxb3+> followed by <28...c2+> and Black's Q-B battery comes into play with fatal effect very nice

| Apr-05-17 | | patzer2: White's decisive mistake was 27. fxe4? which overlooks Black's winning reply 27...Rxb3+! White missed a saving resource and a winning opportunity with a surprisingly strong desperado defense, involving the double piece sham sacrifice 27. Bxe6+! Kxe6 (27... Ke7 28. fxe4 Rxb3+ 29.

click for larger view P.S.: This means Black's rather desperate game move sacrifice 25...Rxb3+!? is not winning, and probably loses with best play to the desperado defense 26. axb3 Rb8 27. Bxe6+! Kxe6 28. Rxd6+! to . However, in a bad position, 25...Rxb3+!? was an excellent swindle attempt (about as good as anything Black had available). Obviously, 25...Rxb3+!? worked to perfection in this game. |

| Apr-05-17 | | patzer2: <ChessHigherCat> Thanks for pointing out another overlooked missed winning opportunity for White with 22. Bc4! Komodo 10.3 gives 22. Bc4! Nc3+ (22...d5 23. Bd3 dxe4 24. fxe4 ) 23. bxc3 (+3.26 @ 25 depth) as best play. |
|
| Apr-05-17 | | mel gibson: so easy. |
|
| Apr-05-17 | | patzer2: Correction: The point of 27. Bxe6+!
is to deny Black the opportunity to play ...Rxb3+ with a mating attack, due to the defense 27. Bxe6+ Ke7 28. fxe4 Rxb3+ 29. Bxb3 .Obviously 27. Bxe6+! Rxb3+ is not possible because Black is in check. |
|
| Apr-05-17 | | saturn2: <Walter Glattke: To Saturn: 27...Qa4 is too slow for grandmasters. White is to pieces ahead, he can Play 28.Bxe6+ Kxe6 29.Rxd6+ Kxd6 30.Bc5+ and move the queen then. >
Black has 30...KxBc5 He has given 3 pieces for free so he is a piece down. I know 27 ...Rxb3 is better but my 27..Qa4 was only a reply to someone that there is only one break through. |

| Apr-05-17 | | pawndude88: <scholes> in your line after Kc8 fxe4 Rxb3+ fails to cxb3 c2+ Qxc2+. Giving check is the dfference. |

| Apr-05-17 | | messachess: Too easy. Almost no puzzle at all. |
|
| Apr-05-17 | | CanITakeThatBack: With a membership to chessgames.com can I move the pieces around on the game and explore different lines that way? |

| Apr-05-17 | | Pballa: White's 22nd move was a clear error. Black is toast after 22. Bc4. That said, black's 22nd move was a very nice find. White still holds an edge with correct play, but it's not easy to find. A better puzzle would be white's 27th move. Finding 27. Bxe6+ followed by 28. Rxd6+ is more difficult for most chess players than the given puzzle, as most players approach puzzles with an "attack" mentality. White stops the mating attack and retains an edge in the endgame due to black's exposed king. There are far too few good defensive puzzles on this site, IMO. |

| Apr-05-17 | | stst: <A better puzzle would be white's 27th move. Finding 27. Bxe6+ followed by 28. Rxd6+ is more difficult..> Good suggestion, esp. to CG!!
Don't just present the game, cut it at some point (no question CG did some homework to have an interesting cut,) and call it a puzzle. One step back: a puzzle is somewhat different from a problem. While a puzzle embraces a problem, the reverse is not true in general. A puzzle usually adds to a problem at core some additional features, confronting the audience with some form of mystery, confusion, hard to distinguish right from wrong, and got one uneasy, mired, and "puzzled!" Whereas a problem presents a number of hurdles, demanding a solution, which, of course, may not be apparent at all, too.
Well, unless we don't really mind if one means the other. Enough, one example:
Puzzle: Why do things (or, to that extent, the universe!) exist at all? Problem: How to find living things beyond the earth? |

You know, if we're looking for a pun. |

Oh, wait ... this was actually a Wednesday puzzle. Nice easy one, with a twist that's sure to bring a smile. |
