| Jul-31-15 | | greed and death: As Everett said, 32... Nxf4 <was> obvious. The follow up starting with 33... Rxa2, on the other hand, was not. |
|
| Jul-31-15 | | agb2002: The material is identical.
White threatens 33.gxh5.
The black queen x-rays the white king and the bishop on g7 x-rays the knight on e5 and the bishop on b2. These details lead to consider 32... Nxf4: A) 33.Qxf4 Rxa2
A.1) 34.Rc2 Rxb2 35.Rxb2 Nh5
A.1.a) 36.gxh5 Bxe5 37.Kh1 (37.Qxe5 Qxe5+ followed by 38... Qxb2 wins) 37... Bxf4 - + [Q+B+2P vs R+N]. A.1.b) 36.Qf2 Qxe5+ 37.Kg1 Qxb2 wins decisive material (38.Rd2 Qc1+ 39.Bf1 Nf4 40.Qxf4 Qxc5+). A.1.c) 36.Ncd7 Nxf4 37.Nxb8 Bxe5 38.Nd7 (38.Ra2 Nxg2+ 39.Kg1 Rxb8 40.Rxg2 Bxg2 41.Kxg2 Rc8 - + [B+2P]) 38... Bxb2 39.Bxd5 Nxd5 - + [B+2P]. A.2) 34.Rd2 Rxb2 looks similar to A.1.
A.3) 34.Ncd7 Nxd7 with two extra pawns and a won position (35.Nd3 Rxb2 36.Qxb8 Rxg2+, etc.). A.4) 34.Ned3 Rxb2 as in A.3.
A.5) 34.Ncd3 Rxb2 35.Nxb2 Bxe5 wins.
B) 33.Ncd7 Nxd7
B.1) 34.Qxf4 Rxa2 transposes to A.3.
B.2) 34.Nxd7 Qd6 35.Nf6+ Bxf6 36.Bxf6 Nxg2+ - + [N+P]. C) 33.Ned7 Nxd7 34.Nxd7 Qd6 transposes to B.2. |

| Jul-31-15 | | agb2002: My 35... Nh5 is met with 36.Qxf7+. I saw the obvious 35... Nxg4+ but don't remember why I preferred 35... Nh5. |
|
| Jul-31-15 | | morfishine: <32...Nxf4> Interesting type of deflection draws the target into the line of fire 32...Rxa2 was worth a look, but comes up a little short ***** |
|
| Jul-31-15 | | cocker: Such hard puzzles kill the response. |
|
| Jul-31-15 | | wooden nickel: White even pushed Black into 32... Nxf4, after attacking Black's knight with the pawn 32.g4
now White must play 33.Qxf4. ... he who says A must say B, at any rate,
many players, might naively follow with 33... Rxa2, thinking a pawn is a pawn (i.e. at least 2 pawns for a piece),
but it's much more, if White defends with 34.Ncd3 giving a new puzzle position with Black to play and win:

|
| Jul-31-15 | | dfcx: material even, black's knight under attack by pawn.
32...Nxf4 33.Qxf4 Rxa2!
Now white can't defend b2/e5/g2 at the same time.
A. 34.Rc2 Rxb2 35.Rxb2 Nxg4+ 36.Qxg4 Qxe5+ 37.Kh1 Qxb2 38.Bxd5 exd5 Black ends up with three extra pawns. B.34.Ncd3 Rxb2 35.Nxb2 Nxg4+ 36.Qxg4 Qxe5+ 37.Kh1 Qxb2 38.Bxd5 exd5 with a slight edge for black. Any other moves? |

 | | Phony Benoni: <Request to Puzzle followers> It looks as though I will be without Internet access this weekend, and unable to update my collections. If someone could leave a quick kibitz in my forum referencing the games used, I'll appreciate it. Thanks. |
|
| Jul-31-15 | | Cheapo by the Dozen: 32 ... Nxf4 was obvious.
33 ... Rxa2 was pretty easy to find.
But at that point I counted 8 possible tries for White on Move 34, and I didn't feel like working those through in detail. |
|
| Jul-31-15 | | kevin86: White has no defense as his position leaks all over! |
|
| Jul-31-15 | | LucB: <Phony Benoni> I can reference the Saturday and Sunday puzzles for you., no problems. (I'm sure I won't be the only one). |

| Jul-31-15 | | thegoodanarchist: <playground player: WWPBD? I only throw it out there as a question.> Ah, yes, WWPBD? A VERY common abbreviation. It stands for "What would Paul Bunyan Do?" Likely he would go out to the barn and feed Babe, his Blue Ox. |

 | | Penguincw: This week's puzzles haven't really been that hard, so who knows, maybe I could've gotten this puzzle here! Unfortunately, I was only thinking about whether or not to capture the bishop on g2, or sac on f4 first. :| |
|
| Jul-31-15 | | saturn2: I calculated the game line until move ..35Nxg4. But then after 36 Kg1 Bxe5, 37 Qd2 BxRb2 38 QxBb2 I thought that white has one piece more, so I dismissed the whole line. In fact both have an equal number of pieces and black has some pawns more.
- Elementary counting error. |

Excellent offshoot and not easy at all to spot:
37... g5! 38.Qxe5
(if Qg3 then 38... Re2+ 39.Nf2 Rxf2+ 40.Kh1 Qxg3)
38... Nxg4+ 39.hxg4 Bxe5+

37... g5!
38 Qxb4 and now? |

| Jul-31-15 | | wooden nickel: <saturn2: @wooden nickel: Jimfromprovidence:

37... g5!
38 Qxb4 and now?>
nice try, but I think it mates:
38.Qxb4 Re2+ 39.Kg1 Qh2+ 40.Kf1 Qg2# |
|
| Jul-31-15 | | thegoodanarchist: 32. Bd4 seems to me to be White's only reasonable try to save the game. |
|
| Jul-31-15 | | BOSTER: <playground player: WWPBD?>. He'd
ask:" Who brought the knight d3 to protect white Queen?"
Better 37.Rf1. |
|
| Jul-31-15 | | haydn20: Just too deep for me. Yes I saw the potential of ...Ra2 but not all the whens and hows. This looks more like "insane" level to me--but I could just be having a bad day. |
|
| Jul-31-15 | | rahulthemoron: chrisowen reminds me of the blue people in the movie Avatar - the language is probably exact and meaningful in its own way, but not to us commoners, who simply avoid reading it. |
|
| Aug-01-15 | | saturn2: @wooden nickel nice try, but I think it mates:
Yes, after g5 white looses in any line. |
|
| Aug-01-15 | | patzer2: For my Friday Jul 31, 2015 solution I found 32...Nxf4! 33. Qxf4 Rxa2  but had difficulty with the follow-up.The follow-up move 34...Rxb2!  is essential because it is the only strong winning continuation. P.S.: White's decisive mistake was 32. g4? allowing 32...Nxf4! . Instead, 32. Bd4! = holds. |
