What a magnificent example by Caruana of <EVALUATE FORCING MOVES LIKE A COMPUTER!>. <30.Red1?

| Feb-16-08 | | notyetagm: Position after 29 ... ♕d7-e7
click for larger viewWhat a beautiful position to have as Black. The <CENTRALIZED> Black d5- and e4-knights together with the <SWINGING> Black f5-rook leave a strong impression. Outstanding positional play by Caruana (Black) to obtain this position. And then after the blunder 30 ♖e1-d1?, all of the well-placed Black pieces spring into life with the <DESTRUCTIVE SACRIFICE> 30 ... ♘d5xe3+!. Position after 30 ♖e1-d1? ♘d5xe3+!

click for larger view30 ... ♘d5xe3+! 31 f2xe3
click for larger viewNotice how the <DESTRUCTIVE SACRIFICE> 30 ... ♘d5xe3+! 31 f2xe3 has -greatly- weakened both the <SQUARES> and <LINES> around the White f1-king: 1) the g3-square is now undefended, allowing 31 ... ♘e4-g3+, 37 ... ♗b8-g3+ 2) the e3-square is now undefended, allowing 32 ... ♕e7xe3+ 3) the e1-h4 diagonal has been weakened, allowing 37 ... ♗b8-g3+ 4) the f-file has been half-opened, creating the <PINNING CHAIN> Black f5-rook + White f3-knight + White f1-king So in exchange for his sacrificed knight, Black's 30 ... ♘d5xe3+! gives him tremendous compensation in the form of the profound weaknesses created around the White f1-king. It is no wonder that Black is able to use these weaknesses to win material and force immediate resignation. |

| Feb-16-08 | | notyetagm: This magnificent Black win by Caruana is an excellent advertisment for the Slav Defense (Queen's Gambit Declined Slav (D11)). |
|
| Feb-16-08 | | Gilmoy: Actually, it's much simpler than that. White's Ba5 is hanging. 28..Rf5 "attacked" it, 30.Red1? didn't defend it. 30..Nxe3+ wins a pawn (via Rxa5). All the rest (2nd pawn + exchange) was just a bunch of zwickenzugs :) |
|
| Feb-16-08 | | HOTDOG: perhaps before 30.Red1? White was slightly better |

| Feb-16-08 | | Gilmoy: Nxe3+ was destructive, but not a "sacrifice". It's just a trade (of N for B). We've all punished a newbie's Nh4 with Nxe4, Nxe4 Qxh4 a pawn up. From the repetitions, it seems like even Caruana hadn't worked out the line in entirety yet, and was making it up as he went :) |

He should have been thinking about his time! Very poor time managament by Caruana, mindlessly repeating those moves. :-)

| Feb-16-08 | | ruelas007: Or maybe he was repeating to be closer to the 40th move? |
|
| Feb-17-08 | | Atking: It seems that <notyetagm> has found another chess young talent. Yeah I hope too that Caruana will be soon on the 2700 club! |

| Feb-17-08 | | mindkontrolle: nice Caruana!!!!!!! |
