 | | perfidious: <GSM....I was patting myself on the back for choosing the game line, but it's clear that my analytical skills could use some improvement.> Can't we all do a little better that way? I am far from perfect, for dang sure! |
|
| Jan-26-17 | | Gregor Samsa Mendel: <perfidous>--You are being kind, but I really suck. I rarely even get Thursday-level puzzles. |
|
| Jan-26-17 | | dfcx: I see that after Ne7+ the black queen is pinned and can't take the knight. Now the rest follows 38.Ne7+ Kf7 (or the queen is lost)
39.Nxc6 Qxc4
40.Nxe5+ forks and wins the queen back
40...Kg8
41.Nxc4 Rc3
42.Ne3 Rxc7
43.exf5 winning two pawns in the process.
The other line 39.Qxe6 seems more complicated, in the end white keeps the extra piece but loses some pawns after 38.Ne7+ Kf7
39.Qxe6+ Kxe6
40.Nxc6 Kd7
41.Nd8 Bc5
42.Nb7 Bxf2+
43.Kxf2 Ra2+
44.Ke1 Kxc7

| Jan-26-17 | | scholes: <Gregor> 39 Qxe6 is only slightly better. Both are winning |

One idea that should immediately draw attention is the white queen being in line to pin the black Q+K. This pin is sprung by moving the interposing Nd5, which happens to be able to give check at f6 or e7. Of those two choices, <28.Ne7+> has the benefit of attacking black's Bc6.

The knight cannot be captured. Black's queen is pinned, and 38...Bxe7 loses the queen to 39.Qxe6. So the king must move up to defend his queen via <38...Kf7>,

White exchanges queens and scoops up the hanging bishop with <39.Qxe6+ Kxe6 40.Nxc6>. But there's a catch! Black's K can fork white's B and N with <40...Kd7>

This little conundrum is what makes this a Thursday puzzle instead of Tuesday. White's resourceful knight has <41.Nd8!>

So now 41...Kxc7 is met by 42.Ne6+ forking and winning the other bishop. Otherwise, the white bishop can retreat to b6. However, we're not done yet! Black has a better option: <41...Bc5!>

This (1) prevents Bb6, and (2) gets close enough to the black king that a Ne6+ fork won't work. White gets the last laugh anyway with <42.Nb7!>, getting out of the king's range while attacking black's bishop. If <42...Bd4> (getting away from the N attack while still preventing Bb6, white has <43.Bd6>

The B is guarded by the N, and the N is guarded by the R (and the R still prevents back-rank mate), and white narrowly hangs on to his piece advantage. |

| Jan-26-17 | | agb2002: White has a bishop and a knight for the bishop pair. The first idea that comes to mind is 38.Ne7+ Kf7 (38... Bxe7 39.Qxe6+ wins) 39.Qxe6+ Kxe6 40.Nxc6: A) 40... Rc3 41.Nd8+ Kd7 42.Bb6 wins a piece since Black cannot trap the knight. B) 40... Kd7 41.Nd8
B.1) 41... Kxc7 42.Ne6+ Kd6 43.Nxf8 Ra7 44.Rd1+ Kc6 (44... Ke7 45.Nxh7 wins a piece) 45.Ne6 h6 (45... fxe4 46.Ng5, etc.) 46.exf5 gxf5 47.Rc1+ Kd6 48.Nc5 Rc7 49.Nb3 + - [N]. B.2) 41... Bc5 42.Nb7 Bd4 (42... Kxc7 43.Nxc5 + - [N]) 43.Ba5 + - [N]. |
|
| Jan-26-17 | | AlicesKnight: 38.Ne7+ looks promising; Black can only reply ...Kf7 to ensure the Q. But now 39.Nxc6 is playable and if ...Qxc4 then 40.Nxe5+ wins the Q back, or if not the Qs can exchange, either way leaving White a piece up. Let's see .... Hmmm - only part-way there, but the Ps are good enough to force a win. |
|
| Jan-26-17 | | gofer: Well this one is "obvious". The knight check on e7 or f6 must
be the solution. The former allows us to take Bc6 with out
losing tempo. Then the light bulb moment. The icing on the cake! We don't take the queen immediately, we exploit the beauty of
our knight and simply take Bc6. When black takes our queen we
take Pe5 winning the pawn and taking back the queen
with a royal fork!
Nice! Job done!
<38 Ne7+ Kf7>
<39 Nxc6! Qxc4> <40 Nxe5+ K move> <41 Nxc4 ...>
click for larger viewWe win a pawn and a piece. What could be wrong with that...? <41 ... Rc3>
Doh!
So today was not the slam-dunk that I had foreseen. Instead it
was a pawn, maybe two. Did we have to see <41 ... Rc3> and then
<42 Ne3>? If we did then this is indeed <Medium>... ~~~
I see there is an even more complicated line, where we try to
keep the bishop advantage! So really I almost got no where today... |
|
| Jan-26-17 | | Eusebius: Excellent and stunning fighting game. |
|
| Jan-26-17 | | kb2ct: Not s easy as at first sight.
There are two ways for black to try to avoid the loss of a piece
Both however fail, but both must to worked out in advance. :0) |

| Jan-26-17 | | thegoodanarchist: Sweet, Babu! |
|
| Jan-26-17 | | morfishine: <38.Ne7+> |
|
| Jan-26-17 | | saturn2: Ne7 doublecheck, queen exchange and take the bishop. The crazy knight withdraws itself and forks afterwards so white remains a piece ahead. Too bad I did not see QxB QxQ and the fork Ne5. |

 | | Jimfromprovidence: <gofer> <38 Ne7+ Kf7> <39 Nxc6! Qxc4> <40 Nxe5+ K move> It looks like <YouRang> and <gofer> are on to something. It seems that any king move on 40 for black does not get compensation for the piece except for the text 40...Kg8. For example, if 40...Ke6?!, then if 41 Nxc4 Rc3 occurs, here is the position.

| Jan-26-17 | | kevin86: a long.last laugh for white. |
|
| Jan-26-17 | | patzer2: For today's Thursday solution, I got the first moves 38. Ne7+ Kf7, but like several others here I deviated from the game continuation with 39. Qxe6+  .According to the computers the game continuation 39. Nxc6! Qxc4 40. Nxe5+ (+2.11 @ 24 depth, Deep Fritz 15) and 39. Qxe6+ Kxe6 40. Nxc6 kd7 41. Nd8! (+2.40 @ 24 depth, Deep Fritz 15) both win and are about equally effective. However, after 39. Qxe6+ Kxe6 40. Nxc6 kd7 I did not see the clever 41. Nd8! pointed out by <Jimfromprovidence> to win back the piece with a second Knight Fork after 41...Kxc7 42. Ne6+ King moves 43. Nxf8 . |

 | | Fusilli: <Jimfromprovidence> <It's white to play and keep his piece advantage.> From your diagram, I think 42.exf5+ gxf5 (42...Kd7 43.Nb6+ wins) 43.Re1+ keeps the piece, the most blurry variation being 43...Kd7 44.Nb6+ Kc6 (44...Kxc7 45.Nd5+) 45.Be5 (45.Bd8 Rd3 seems strong) and it seems that after 45...Rc2 46.Na4 keeps the piece. |

| Jan-26-17 | | JohnBoy: I pretty much ch immediately saw the game line & quit. Didn't even examine 39.Qe6+. Good players pause to check for improvements. That I often didn't was always a shortcoming in my game. |
|
| Jan-26-17 | | mel gibson: The first move is obvious.
Less obvious is where it leads. |
|

| | Jimfromprovidence: <Fusilli> Yeah, you nailed it. Wow, we have commentary from <Fusilli> Jerry? and a player named Babu. |
|
| Jan-26-17 | | drollere: a pretty combination! |
|
| Jan-27-17 | | patzer2: For a Black improvement, instead of 7...Ne7 which allows 8. Bf4  , I prefer 7...Nc6 = as in A Choukri vs S P Sethuraman, 2015 or M Dietmayer-Kraeutler vs K Jakubowski, 2015. |
|
| Jan-08-21 | | Messiah: Very nice game by mister Lalith, the combination was pretty well calculated, I guess. |
