| Apr-18-14 | | Cheapo by the Dozen: At first glance this looks trivial. 31 ... Rxf5, and the rook is poisoned because of 32 ... Bd5+ I wonder what I'm overlooking. |
|
| Apr-18-14 | | patfoley: You may be overlooking a Q sacrifice in the aftermath of BN2 |
|
| Apr-18-14 | | patfoley: Well it looks like a Q sacrifice. Or a B sacrifice. |
|
| Apr-18-14 | | ClaudioSottile: Well an easier way to win after 34. Rf3 is simply 34... Bf3 and now only adequite defence to stop mate on f1 by promoting to queen is 35. Qf1 which fails to ...Bg2 Qg2 ...f1Q and Qf1 and ...Qf1 mate. |
|
| Apr-18-14 | | ClaudioSottile: Scratch that, I missed the perpetual draw white had but its one type of variation to keep in mind for tactics. |
|
| Apr-18-14 | | dick50: After 34 Rf3 Bxf3 white can play 35 Qxg5+ and may escape with a draw by repeated checks. |
|
| Apr-18-14 | | cyclon: I'd play 31. -Rxf5 32. exf5 ( in other cases White just loses a piece for nothing or otherwise quite immediately, f.e. 32. Qb2 Nxe4 wins [33. Rxe4 Bd5] / 32. Qc2 [32. Qd2 Nf3] -Rf8 is a simple move winning pure piece in a better position / 32. Qd1 Nf3 33. h4 [33. h3 Rf8] -Nxh4 [33. -Rf8 intending -Nd4 is a positional winning-line] 34. gxh4 [34. exf5 Nf3+ mates] -Rf3 [ 34. -Qxh4+ 35. Rh3 'disturbes' a bit] 35. Rxf3 gxf3 White's position is lost / 32. h4 Nxe4 Black wins ) -32. -Bd5+ 34. Bg2 Qh3 35. Qf1 [35. Bxd5 f1Q+ 36. Qxf1 Qxf1X] -Qxg2+ mates next. |
|
| Apr-18-14 | | Cheapo by the Dozen: Oh. Bishop interposition. Duh.
I didn't solve it accurately in the face of that. Oh well. |
|
| Apr-18-14 | | agb2002: Black is one pawn down.
The black king is under check.
The obvious move is 31... Rxf5, weakening the light squares around the white king, 32.exf5 Bd5+ 33.Bg2 Qh3: A) 34.Bxd5 f1=Q+ 35.Qxf1 Qxf1#.
B) 34.Qf1 Qxg2+ (or 34... Bxg2 35.Qxg2 f1=Q+ 36.Qxf1 Qxf1#) 35.Qxg2 f1=Q(R)#. C) 34.Re4 Nxe4
C.1) 35.Bxh3 Nxg3#.
C.2) 35.Qe3 Nxg3+ 36.Qxg3 f1=Q(R)#.
C.3) 35.f6+ Kh8 doesn't seem to change anything.
D) 34.Rf3 Nxf3
D.1) 35.Bxh3 Ne1+ 36.Bg2 Bxg2# (or 36... f1=Q(R)#).
D.2) 35.Bxf3 Bxf3#.
D.3) 35.f6+ Kh8 doesn't seem to change anything.
E) 34.f6+ Kh8 ditto. |
|
| Apr-18-14 | | cyclon: Almost, but not quite. I missed this peculiar game-line consisting about the defence 34. Rf3 and now White threatens 35. Qxg5+ ( this move is what I missed at first). Interesting is that Black still wins. As a consequence, naturally I missed 35. -Nxf3!! too. Cufflinks for Black! |
|
| Apr-18-14 | | patzer2: Black has two ways to solve today's Friday (31...?) puzzle. Either 31...Bxf5 32. exf5 Nf3 33. Rxf3 gxf3  or the game continuation 31...Rxf5!! 32. exf5 Bd5+ 33. Bg2 Qh3! work. In the game continuation, an amusing defensive possibilty is 34. Re4!? (diagram below) 
click for larger viewHere 34...Bxe4? blunders and gives White a draw by perpetual after 35. Qxg5+ =. Instead 34...Nxe4! wins due to the mate-in-two threat 34...Nxe4! 35. Bxh3? Nxg3#. |
|
| Apr-18-14 | | Nick46: A classic case of the <Dutch Defense: Leningrad. Matulovic Variation> Who thinks up these names fer gaaawds sake, and who learns them off by heart? |
|
| Apr-18-14 | | morfishine: <31...Rxf5> 32.exf5 Bd5+ looked very strong, but after 33.Bg2 I had trouble visualizing 33...Qh3 <patzer2> Your second variation ending in 35...Nxg3# is more than "amusing"; Its important as it demonstrates an additional line on this B+N theme. Very nice! ***** |
|
| Apr-18-14 | | gofer: This all looks pretty forced...
<31 ... Rxf5>
Black cannot afford to refuse the sacrifice as losing Nf5 for nothing is as good as losing anyway... <32 exf5 Bd4+>
<33 Bg2 Qh3!>
At this point black can give up trying to defend as all responses seem to lose... 34 Bxd5 f1=Q+
35 Qxf1 Qxf1#
34 Qf1 Bxg2+
35 Qxg2 f1=Q+
36 Qxf1 Qxf1#
34 Re4 Nxe4!
35 Bxh3/Qf1 Nxg3#
34 Rf3+ Nxf3!
35 Bxh3 Bxh3
36 Ne1+ Bg2
37 f1=R#/Bxg2#
34 f6+ Kxf6!
35 Re4 Nxe4!
36 Bxh3/Qf1 Nxg3#
34 f6+ Kxf6!
35 Rf3+ Nxf3!
36 Bxh3 Ne1+
37 Bg2 f1=R#/Bxg2#
<34 Rf3 Nxf3!>
<35 f6? Kxf6>
<36 Bxh3 Ne1+>
<37 Bg2 f1=R#/Bxg2#> ~~~
Yep... |
|
| Apr-18-14 | | parmandil: After white interpolates the rook, either on e4 or f3, there is also the more prosaic 34... f1Q+ followed by 35... BxR. |
|
| Apr-18-14 | | diagonalley: neat... very neat!... managed to visualise most (though not all) the sequence)... worthy of a perfectly bog-standard friday |
|
| Apr-18-14 | | kurodo77: 31...Bxf5
32 exf5 Rh8
33 f6+ Kxf6
and now? Checkmate in h2. |
|
| Apr-18-14 | | Ratt Boy: Me likey the Leningrad Dutch. Been playing it for 40 years. (I almost got the puzzle. I had 31…♖xf5 32.exf5, ♗d5 33.♗g2, ♕xh2+ 34.♔xh2, ♖h8+ and mate to follow. Bummer that I didn't have a Rook to play to h8.) |
|
Apr-18-14
 | | Penguincw: 31...Rxf5 32.exf5 was pretty easy to spot , but I didn't catch 32...Bd5+. |
|
| Apr-18-14 | | PJs Studio: I calculated all of it but chose 35...Nh4+
Does that mean I got it wrong? |
|
| Apr-18-14 | | JohnBoy: I saw <cyclon>'s line but finished with 35.Qf1 Bxg2 36.Qxf2 f1Q+ - one move longer to mate. |
|
| Apr-18-14 | | kevin86: Black is in check. So save the bishop, open lines for him ,and force checkmate! |
|
| Apr-18-14 | | Patriot: 31...Rxf5 32.exf5 Bd5+ 33.Bg2 Qh3
34.Bxd5 f1=Q+
34.Qf1 Qxg2+ 35.Qxg2 f1=Q# |
|
Apr-18-14
 | | Jimfromprovidence: A cool variation is after 32 Qc5. Black wins beginning with 32...Qh3!
