| Sep-19-06 | | Autoreparaturwerkbau: 10.Nxg6! prepares an interesting kingside attack. |
|
| Aug-20-11 | | Whitehat1963: Thursday puzzle after 13...Kg8. |
|
| Dec-08-11 | | Quentinc: Vastly easier than yesterday's. I missed yesterday's altogether (I was part of the Rxa5 crowd); this one took less than a minute. |
|
| Dec-08-11 | | Infohunter: Another familiar mating pattern presents itself in today's puzzle. I have to agree that this was easier than yesterday's--I too made the Rxa5 mistake on that one. |
|
| Dec-08-11 | | heuristic: can't BLK hold on by opening f8 for the K to escape?
15...Bb4+ 16.Kf1 (or Ke2) Qe7
and WHT is left with Qxg4 |
|
| Dec-08-11 | | Chesster13: Black has to give up a rook to prevent checkmate on the 15th move. 15... Rh7
16. Bxh7
Other than that, I can't think of a way to get out of it. |
|
| Dec-08-11 | | shaikriyaz: got it in no time:-) |
|
| Dec-08-11 | | Aware: <can't BLK hold on by opening f8 for the K to escape? 15...Bb4+ 16.Kf1 (or Ke2) Qe7
and WHT is left with Qxg4>
Yes that seems to work. I guess it's not easier than yesterdays. |
|
| Dec-08-11 | | IRONCASTLEVINAY: Never saw this game before,, BUT FOUND THE ENTIRE LINE IN 5 SECONDS.(Maybe 7) |
|
| Dec-08-11 | | Aware: Have you guys seen what heuristic posted?! |
|
| Dec-08-11 | | IRONCASTLEVINAY: Never saw so many weak white squares. |
|
| Dec-08-11 | | IRONCASTLEVINAY: where the black actually go wrong? anyone?? |
|
| Dec-08-11 | | Aware: I was also looking at 14... Rc8 15. Qb3 Qa5+ attacking that knight so it must retreat. Idk I think Nxd5 is winning, but there is still some game left. |
|
| Dec-08-11 | | Mendrys: <IRONCASTLEVINAY>, 7..d6 seems dodgy to me because it allows white to force h6 and the subsequent weakening of the pawns around black's king. |
|
| Dec-08-11 | | Madman99X: 14. Nxd5 exd5 15. Qf5 Bb4+ (heuristic) 16. Ke2 Qe7 17. Qxg4
click for larger view Advantage to white, I think, but certainly not decisive. Rybka at 17 ply gives:
Nf8 -1.26
Nf6 -1.30
h5 -1.35 |
|
| Dec-08-11 | | M.Hassan: "Medium" White to play 14.?
Equal on sides:
The only line that I see is a Knight sac:
14.Nxd5 exd5
15.Qf5 threatening mate on f7
15........Bb4+
16.Ke2 Qf6
17.Qxg4 Qc7
18.Bd2
White falls ahead by a pawn but has ways to go for a win if there will be a win. Will check to see how the game continued ---
Up to 15.Qf5 is identical to my line. Then 15...Bb4+ is in fact a saver of Black against checkmate in my line because removal of Bishop from f8 provides escape square for the King to move to and I can't understand why Black has not done so |
|
| Dec-08-11 | | whitecrow: What happens if black decline the knight sac? |
|
| Dec-08-11 | | rilkefan: So the normal first candidate 14.Nxd5 looks pretty obviously strong - if exd5 then Qf5. But I'm not sure if Bb4+ or something is enough to keep fighting after Qe7 or f6. Well, black is basically down a rook on top of his other problems. |
|
Dec-08-11
 | | al wazir: 14. Nxd5 is an obvious candidate, and after 14...exd5, 15. Qf5 threatens mate three ways. I'm on a roll this week. |
|
| Dec-08-11 | | dzechiel: White to move (14?). Material even. "Medium."
It looks like white can win a pawn with
14 Nxd5
Black cannot recapture because after
14...exd5
white plays
15 Qf5
and there's no way to prevent checkmate. If black does nothing significant, then 16 Qf7# will be mate. Other tries fare no better: 15...Ndf6 16 Qe6#
or 15...Qf6 16 Qxd5+ Qf7 17 Qxf7#
You get the idea. Black is probably best taking his lumps with 14...Ngf6
Time to check. |
|
| Dec-08-11 | | Gilmoy: <whitecrow: What happens if black decline the knight sac?> I saw that as part of my solution: "Shirley he can't take it!" 14.Nxd5 <not exd5> 15.Qe4 with the same diagonal mate theme, it's too late to take the N now (15..exd5 16.Qe6+), and the Nd5 perfectly covers b6/e7/f6, so Black's Q has no square to defend e6. |
|
| Dec-08-11 | | Gilmoy: <dzechiel: 14.Nxd5 Ngf6> Best I can see is 15.Nf4 <not 15.Nc7 Rc8 16.Qb3 Qe7 17.Nxe6 Qb4+ and White has work to do> Rc8 16.Qb3 Qe7 17.Bd2 Rc6 and Black is all tied up: White has Rg1-Ke2 if he's patient, or Bf5-Ng6 if he really wants e6. |
|
Dec-08-11
| | al wazir: 14. Nxd5 Nde5! 15. Qe4 (or 15. dxe5) Qxd5, and black stays alive -- for a little while anyway. |
|
| Dec-08-11 | | egs: <IRONCASTLEVINAY> I think black went wrong by letting the knight hang out on e5. I think black should've traded it off right away. The error was compounded by blocking off the bishop's escape with 7...e6 which is what lead to the white square weakness. Also, according to opening explorer 6...Nbd7 never leads to a loss or draw for white. It also doesn't occur very often though. So maybe that could count as the flaw. |
|
| Dec-08-11 | | lost in space: easy to spot.
14. Nxd5 exd5
(14...Ngf6 15. Nf4 and white is up a pawn and should win) 15. Qf5 with a lot of threats: mate on f7, mate on d5, mate on e6 and - not important - also Qxg4 15...Ngf6 and also Ndf6 16. Qe6#
15...Qf6 16. Qd5+ Qf7 17. Qxf7#
15...Qe8 16. Qd5+ Qf7 or Qe6 17. QxQ# |
