| Feb-16-10 | | Dr. Funkenstein: wow, Kamsky flattens a 2600 starting with the clever 14. ... Nxe4! White has to give back the piece because if Qf3 then f5 and if Qd3 then Nb4. |
|
| Feb-16-10 | | Starf1re: Nice combination by black! |
|
| Feb-16-10 | | Starf1re: The silicone hydra recommends 15)Q c2 for white. 16)Qe3 is losing. |
|
| Feb-17-10 | | Dr. Funkenstein: You (and hydra) are right Starf1re, how does black respond after Qc2? |
|
| Feb-18-10 | | Starf1re: After QC2, white is still in an ugly predicament after kb4 Qxe4 bf5. If you're interested in analysis Babaschess comes with Crafty chess engine and you can also download Rybka for free and select it with Babaschess to analyze. |
|
| Feb-20-10 | | Dr. Funkenstein: sorry, I meant 16. Qc2 where Nb4 is answered by Qc5 |
|
| Jul-12-14 | | Thumbtack2007: <funkenstein> 16.Qc2 is better, but White has an inferior position after 12.Qd2. 12.Rd1 is better, but we get a sporty game after 12..Nb4 13.Qb1 Nxe4 14.Nxe4 Bxa2 15.Qc1 Bd5. Even position, but lots of play on both sides. I would have liked to see the continuation on this line. |

 | | al wazir: The first thing I noticed was that the black ♕ doesn't have much scope. If the f3 ♘ were on d4, white would win at least a piece with 14. Na4 Qb4 (14...Qa7? 15. Nb5) 15. Qxb4 axb4 16. dxe6. But that ♘ isn't on d4, it's on f3. The second thing I saw was that 14. dxe6!? Rxd2 15. exf7+ Kxf7 16. Bc4+ Re5 17. dxe5 is the kind of speculative gutsy attack I would expect to work in a Saturday puzzle. But it doesn't seem to go anywhere, so I settled for 14. Na4 Qa7 15. Qxa5 Bd7 16. Nc3, winning a ♙. What??? It's BLACK to move?
Nuts. |

| Jul-12-14 | | Cheapo by the Dozen: I presume the move is 14 ... Nxe4, and I think it gets Black a material advantage of at least 4 pawns for the piece, with my main line being: 14 ... Nxe4
15 Nxe4 Bxd5
16 Qe3 Bxa2
17 Ra1 Bd5
18 Rb1 Bxb2
after which the dual threats of Bc3+ and Ba7 keep White from successfully exploiting the pin. As for White's counterplay, Black should be able to keep something on the long black diagonal to defang and attack on his king, and I think he will have time for e6 before his threatened e-pawn is an issue. Move 15 note: The sacrifice can't be declined because of 15 ... Nxc3, which threatens 16 ... Nxb1. Move 16 note: White has to get his queen off the d-file, to a square defending e4 -- i.e., his possible moves are Qe3 and Qc2. But the line 16 Qc2 Nb4 gets the piece back for Black after all, so 16 Qe3 is forced. |
|
| Jul-12-14 | | Cheapo by the Dozen: Ack. I considered the Bd4 line for Black, but didn't see how tenuous White's defense of the e4 knight was. At least I found the right start, and sufficient justification to play it, so there's some reason to think I would have actually played this position correctly over the board. :) |
|
| Jul-12-14 | | diagonalley: well, i went 14... NxKP, wiping out white's centre and releasing a lot of firepower... though sadly i was unable to calculate much farther |
|
| Jul-12-14 | | Ratt Boy: Nice combo. I got 14…♘xe4 and 15…♗xd5, butt mist the followups which won the e4 Knight. I give myself partial credit. White got himself into this mess by wasting a whole lot of time with Queen moves—five of the first 12. After Move 12, Black has developed all his minor pieces and castled. White has an undeveloped Bishop and is two moves from castling. To boot, the Queen which has peregrinated so aimlessly finds herself dangerously camped on the half-open d-file, just waiting for a tactical smackdown. Kamsky effectively punishes this opening violation, and White never makes it to a half-decent middlegame. |

| Jul-12-14 | | WoodPushkin: Greetings:
14...Nxe4!
Free pawns as the White queen has no safe squares to defend from. The real lesson here is that just because you get comboed on does not mean you have to give away the postion/game! An excerpt from a poem I wrote to teach my students how to think in a position applies: "Just a pawn in the game pursuing royal claim. Terrain I traverse has certainly been well rehearsed and yet its new all the same. Similar troop movement: time, space and quality each seeking improvement. "Peep maneuvering shifts. Don't fall for subtle gifts. If you weren't looking for a horse then out the mouth comes a grift. "Sometimes it can't be avoided. An offer you can't refuse. Slowly choose your next move lest you get blown out your shoes. And blunder a piece or suffer positional bust. Meaning no matter what you move your loss is a must!.. Analysis, Calculation, Execution: Study
Chess..?

| Jul-12-14 | | goldenbear: Moves like 9.Rb1 better be correct... generally, I've found it's better to sac a pawn without preparation, (say 9.Be2), than to just play a "safe" move like Rb1. |
|
| Jul-12-14 | | morfishine: Here, there are no checks and few captures
<14...Nxe4> The only move that offers any initiative <15.Nxe4> practically forced Here, the first problem I had was deciding on 15...Bxd5
or 15...Rxd5; After going over both, I concluded 15...Bxd5
was stronger due to the exposed attack on White's Queen <15...Bxd5> The exposed attack n the White Queen gives Black the initiative, however I
was unable to find the winning line. The problem I had was
I thought White could defend the Knight long enough to allow
himself to castle; for example: 16.Qe3 Bd4 17.Nxd4 cxd4
18.Qd3 Nb4 19.Qf3 f5 20.O-O fxe4
I just didn't think White would toss the Knight instantly
with 18.Qg3

 | | Penguincw: 14...Nxd5 15.exd5 Bxd5 or 15...Rxd5 seems legit to me (well there's 15.Nxd5 too). |
|
| Jul-12-14 | | eblunt: I had 15 ..... ♖xd5 and depending on where the black ♕ moves to, a variety of moves follow , ♗c3+ ♕b4+ ♘c3 or ♖(a)d8 all are possible. It looked likely to get the minor piece back at the very least. Maybe some silicon crunchers out there could confirm ? |
|
| Jul-12-14 | | jdc2: 14...Nxe4 seemed like the only possibility, but after that I didn't get much. Typical late-in-the-week "problem", with no definite solution, it's just a "find the best moves in this position" exercise. Here's what my buddy Stockfish sez: 1...Nxe4 2. Na4 Qa7 3. Qxa5 Bxd5 4. a3 e5 5. Bd2 Nxd2 6. Nxd2 Bxg2 7. Rg1 (2. Qc2 Nb4 3. Qxe4 Bf5 4. Qc4 Bxc3+ 5. bxc3 Bxb1 6. cxb4 axb4
7. Qb5
2. Qe3? Bxc3+ 3. Kf1 (3. bxc3? Qxb1+ 4. Qc1 Qxc1+ 5. Bxc1 Rxd5) Bd4 2. Nxe4 Bxd5 3. Qc2 Nb4 4. Qxc5 Qe6 5. Nfg5 Qf5 6. Be3 Bxe4 7. Qxf5 2. Qd3 Nb4 3. Qxe4 Bf5 4. Qc4 Bxc3+ 5. bxc3 Bxb1 6. cxb4 axb4 7. Qb5 2. Qd1 Bf5 3. Na4 Qb4+ 4. Kf1 Nxf2 5. Kxf2 Qxf4 6. g3 Qd6 7. Rc1) |

 | | agb2002: The material is identical.
The rook on d8 x-rays the white queen. This suggests 14... Nxe4, with the idea 15.Nxe4 Bxd5 threatening ... Bxe4 and several discovered attacks: A) 15.Nxe4 Bxd5
A.1) 16.Qc2 Nb4 17.Qa4 Bxe4 wins two pawns.
A.2) 16.Nc3 Bxf3 wins two pawns at least.
A.3) 16.Qe3 Qb4+ 17.Nc3 Bxc3+ wins two pawns (18.bxc3 Qxb1+). B) 15.Na4 Qa7 16.Qe3 Bxd5 wins two pawns.
I'm sure I'm missing a lot but that's all I can do today. |

| Jul-12-14 | | M.Hassan: Black to play 14....?
Sides are equal
14.........Nxe3
15.Nxe3 Bxd5
16.Qe3 Bd4
17.Nxd4 cxd4
18.Qd3 Nb4
19.Qd2 Bxe4
Black is 2 pawns up |
