 | | Penguincw: Start of March Madness! Good luck to everyone and their bracket! Which do you guys think will happen first, a perfect bracket or #16 defeats #1 (I vote for the latter). Seems like a lot of other events are happening today... Anyway, interesting puzzle. I came up with 39.Rxe6+ fxe6 (not capturing results in promotion) 40.Rg7+ Kd8 (40...Kf8 41.Qxf6# 1-0) 41.Qxf6+, and was stuck from there. However, I was surprised to see that 39.Re6 was the only move played, so I'm 2/2 this week. Looking at the full solution, it's 41...Kc8 42.Qxe6+ Rxe6 (42...Kd8 43.Qd7# 1-0 or 42...Kb8 43.Qxe8# 1-0) 43.h8=Q+ Re8 44.Qxe8# 1-0. |

 | | Phony Benoni: Surely we start with <39.Rxe6+> to open up the 7th rank for the rook. <39...fxe6 40.Rg7+ Kd8 41.Qxf6+ Kc8> ... oh, wait, I see it! <42.Qxe6+!>. If the rook takes it's promote and mate, and 42...Kd8 43.Qd7# or 42...Kb8 43.Qxe8*. Or something like thatl. |
|
| Mar-15-16 | | dfcx: white is down a piece and a pawn but has a pawn next to the last rank. So if white can some how make the black rook disappear... 39.Rxe6+
A.39...fxe6 40.Rg7+ Kd8 41.Qxf6+ Kc8 42.Qxe6+ and mate in two B. 39...Kf8 40.h8=Q+ Ng8 41.Qxg8#
C. 39.. Kd7 40.Rxe8+ Kxe8 41.h8=Q+ Ke7 42.Qxa8
D. 39...Kd8 40.Rxe8+ Kxe8 same as previous. |
|
| Mar-15-16 | | dfcx: In my variation D
after 39...Kd8 40.Qxf6+ is better and quicker.
40...Kd7 41.Qxf7+ Kd8/Kc8 42.Rxe8#
40...Kc8 41.Rxe8+ Kc7 42.Qxf7+ Kc6 43.Rxa8 |
|
| Mar-15-16 | | Cheapo by the Dozen: A little complicated for a Tuesday, in that it would be tedious to work out every variation to the end. I stopped analyzing after getting to: ---
White is down a piece or so, but has an attack and a scary passed pawn. Black, if given enough time, could have counterplay. Of White's many ways to smash through, which include Rf1, Rg7, Rge1, and I suspect even Rg6, I'll choose the most forcing, so that Black doesn't have time for anything like ... Rb8. 39 Rxe6+ fxe6
40 Rg7+ Kd8
41 Qxf6+ Kc8
42 Qf7
seems to leave Black pretty helpless.
But if Black declines the rook, White captures both the bishop and knight with tempo, while keeping his attacking threats and also the advanced pawn. So surely he can win from there despite his exposed king. |
|
| Mar-15-16 | | Cheapo by the Dozen: It looks like White's whole attack was structured around averting ... Re2+. Without that threat from Black, White's win would have been pretty trivial. |
|
| Mar-15-16 | | patzer2: For our Tuesday puzzle (39. ?) White picks up two minor pieces for the Rook after 39. Rxe6+ fxe6 40. Rg7+ Kd8 41. Qxf6  (diagram below),
click for larger viewbut more importantly after 41...Kc8 White forces mate-in-three with 42. Qxe6+! Rxe6 43. h8=Q+ Re8 44. Qxe8#. P.S.: For a Black improvement, the computer suggestion 17...h6  (-0.32 @ 26 depth, Komodo 9.3) would be my preference over 17...Nbd7 = (-0.18 @ 25 depth, Komdo 9.1). |
|
| Mar-15-16 | | nalinw: If one is expected to find
42. Qxe6+
- which one should be in my opinion - and which I didn't get - this is more complicated that the usual Tuesday puzzle |
|
| Mar-15-16 | | stst: could be easy if Black "cooperates."
39.RxB+ fxR
40.Rg7+ Kd8
41.Qxf6+ Kc8
42.Qxe6+ RxQ
43.h9=Q#
but if Black goes other ways, it could be long...
39.RxB+ Kd7
40.RxN dbl+ Kc6
41.Rxd6+ Kb7
....etc
will revisit if got time.... |
|
| Mar-15-16 | | stst: Notation:
CG uses "Re6" practically same as Rxe6, but,
Rxe6 describes also the action of R capturing something and lands on e6, while Re6 may, just a may, give a misleading interpretation that the R simply lands on e6 (where e6 is not being occupied by any piece before R lands on it.) Clumsy... but just some clarification.
(That's why I like the old notation, as, RxB to depict the precise action - but of course, the exact square has not been specified.) |
|
| Mar-15-16 | | morfishine: <39.Rxe6+> |
|
| Mar-15-16 | | agb2002: White is one bishop and one pawn down.
The pawn on f7 is overloaded with the defense of the bishop and blocking Rg7. Therefore, 39.Rxe6+: A) 39... fxe6 40.Rg7+ Kd8 (40... Kf8 41.Qxf6#) 41.Qxf6+ Kc8 42.Qxe6+ Rxe6 (42... Kb8 43.Qxe8#; 42... Kd8 43.Qd7#) 43.h8=Q(R) and mate next. B) 39... Kd7 40.Rxe8+ wins (40... Kxe8 41.h8=Q+, etc.). C) 39... Kd8 40.Qxf6+ (or 40.Rxe8+) wins.
D) 39... h8=Q(R)+ and mate next. |
|
| Mar-15-16 | | NBZ: @nalinw: Qf7 instead of Qxe6+ also mates very quickly, and I think is also a valid solution to the puzzle. |
|
| Mar-15-16 | | Conrad93: A simple deflection puzzle. Not too hard to spot once you see the possibility of Rg7+. |
|
| Mar-15-16 | | lost in space: got that one easily |
|
| Mar-15-16 | | mel gibson: Just like yesterdays - super easy. |
|
| Mar-15-16 | | schachfuchs: I also asked myself: Is it monday or tuesday? ;-) |
|
| Mar-15-16 | | whiteshark: ... and what am I doing here? |
|
| Mar-15-16 | | CHESSTTCAMPS: Black is up a bishop and a pawn, and seems to have substantial piece protection around the uncastled king. However, in chess, just one weak point can kill you. 39.Rxe6+! opens a lateral line of attack and everything falls apart for black: A.39... fxe6 40.Rg7+ Kd8 (Kf8 41.Qxf6#) 41.Qxf6+ Kc8 (Re7 42.Qxf7 mates next) 42.Qf7 (threatening Qxe8#, Qc7#) Qb6 43.Qxe8+ Qd8 44.Nxd6+ Kb8 45.Qxd8# B.39... Kf8 40.h8=Q+ and mate next.
C.39... Kd7 40.Rxe8+! Kxe8 41.h8=Q+ is simplest.
D.39... Kd8 40.Rxe8+ K/Nxe8 41.h8=Q wins.
Note that white's simple N+P shelter defends the white king perfectly. |
|
| Mar-15-16 | | YetAnotherAmateur: Drat, I went with the less forcing 39. Rg7, which still looks effective but not quite as simple, because black can get some time to respond by throwing away material with moves like 39. ... Kd8. |
|
| Mar-15-16 | | kevin86: White sacs the rook to open black's lines to the king. |
|
| Mar-15-16 | | gars: Yesterday's puzzle was tougher than this one. |
|
| Mar-15-16 | | saturn2: After Rxe6 white is ruling. The black king has 3 escape squares but will fall as well as after fxRe6. |
|

 | | Richard Taylor: A fairly obvious but nice attacking strike but Short played a nice game. |
