  whiteshark: 35. ♖xg7+ is eye-catching.
Sep-25-07  Tactic101: Pretty easy. Rxg7+ and Qg5. Works no matter what (whether black accepts or declines the sac).

Why does <aazqua> always have to be so negative and arrogant? Enough is enough.

Sep-25-07  nmp: Hurrah!! Got it for the first time after trying the whole lot of cg puzzles last week..
Sep-25-07  Murphyman: Some Great Advice there <Mostly average Joe>.

Definately a Tuesday Problem

Sep-25-07  aleister23: too easy it is always looking for a sacrifice in these problems....Very Tallesque of you :)
Sep-25-07  nateinstein: Looked at some ? moves at first. Once I considered Rxg7+ it was easy to see that it was the game winning move.
Sep-25-07  pawnofdoom: Easy. Yay I got it! But it was supposed to be easy anyway. Rxg7+ was the only possible sac in the position, and tuesday puzzles are always random sacs. Qd8+ was useless, so it had to be Rxg7+ Kxg7 Qg5+ Kf8 Bxf6 with a double threat on the black queen and checkmate
Sep-25-07  zb2cr: Quick and simple. I found the answer easily if Black accepted the sacrifice, but convincing myself that Black was lost if he declined by 35. ... Kf8 or 35. ... Kh8 took longer, perhaps 30 seconds in all.
Sep-25-07  TrueBlue: I solved a puzzle and everyone shouts how easy it was :( Not cool! And it did take me some time to cover all the bases, there are several lines here, not that trivial.

No need for the frowny face. There were several lines to check here. Particularly because it's a puzzle, the move 35. Rxg7+ should jump out pretty quickly as a strong candidate move, but any one who claims: "Got it in nanoseconds!" didn't check the variations (unless the one making that claim is named Fritz or Rybka, etc.).

  gawain: Two Mondays in one week! I am not complaining. This is the only context I can think of in which two Mondays are a good thing.

  ahmadov: I could find this as a Monday puzzle...
Sep-25-07  znprdx: <MostlyAverageJoe:...finishing puzzles where one side has just an advantage (and not a forced quick mate) may be a good exercise. There is a good reason for it> and absolutely essential in order to develop rapid and blitz skills. There is another reason too - even more important - remarkably there are sometimes surprising counter sacrifices or where simply giving back the material in the event every attackers move is not a check - we have all been there... ye olde losing a won game.

  kevin86: I see a pattern here:yesterday,we sac-ed a queen;today, a rook. Which minor piece will go tomorrow? lol

In think it's not a Monday puzzle because of the possible wrinkle in black declining the sacrifice.

  YouRang: I spent some time on this -- I didn't give up because I hate to miss a Tuesday puzzle. :-)

I spotted 35. Rxg7+ pretty quickly since it's a pretty common attack pattern to bring in the queen with check. I even noticed that after 35...Kxg6 36. Qg5+, I could win the knight at f6 with 37. Bxf6.

What took me some time is that I didn't see that there was a mating attack in the works because my other bishop is blocking off the king's escape. Black must sac his queen (37...Qxf6 38. Qxf6 ) to delay mate. A very nice combo!

tomorrow is Knight time? :)

  playground player: I was going to say that declining the sacrifice doesn't do Black any good, but <Mostly Average Joe> has already demonstrated that abundantly.

  patzer2: The demolition move 35. Rxg7+!, with 36. Qg5 to immediately follow, proves to be a quick and easy solution to today's puzzle.

  fm avari viraf: White is a pawn up & all his pieces are aiming the vital targets & Black's position looks shaky. Hence, the first tactical blow 35.Rxg7+ & whether Black captures the Rook or not his fate is sealed. Chess would have be Dull,Dry, Drab & Dreary sans Tactics & Techniques!
Sep-25-07  TheaN: 2/2

Bit late, still got it.

35.Rxg7+ terminates Black. Accepting first: 35....Kxg7 36.Qg5+ Kf8 (Kh8 37.Bxf6+) 37.Bxf6 Qxf6 and White wins (I noticed that it stil leads to mate in a couple of moves).

Declining seems harder this time: 35....Kh8 36.Qh6 -> Bxf6. If the Knight moves, it's Qxh7# (doesn't seem to be a good reply to Qh6). 35....Kf8 seems the hardest reply. However, 36.Qh6 and Black runs out of moves. At least, White hasn't sacced anything and has a tremendous attack going, but I don't see decent replies:

36....Nh5 37.Rxh7+ Kg8 (Ng7 38.Qxg7#) 38.Rh8#.
36....pretty much any Queen move to avoid mate leads to Bxf6 winning completely.

Sep-25-07  gnixon: Just bragging that I saw this instantly; usually doesn't happen even on Tuesday. On the other hand, I disagree with Ahmadov that this is a Monday puzzle. There are a couple of variations to double-check.
Sep-25-07  not yet a patzer: <Mostly Average Joe <not yet a patzer: I suppose if the Black King does NOT take the rook but goes to, say f8, then 36.Qg5, and I can find no response that prevents Rg8#> But there are plenty!>

I did all of my "analysis" (definitely using the term loosely) without the aid of a board, so I missed the knight covering g8. (I know this is a lame excuse, I should have plainly seen it.) And I knew that if the Black Queen moved that the King would be able to slide out of a back row attack at g8. When you describe it, it is all so clear that I wonder how I could miss it.

Oh well. I love chess anyway. And I greatly appreciate your response.

Sep-25-07  xrt999: 34...Qe7 is a blunder. I mean, what is black trying to achieve with Qe7 anyway? I dont get these puzzles. Black plays a move like Qe7, then resigns on whites next move. If you can see whites next 3 moves to win the game you should have seen Qe7.

  plang: 19..Qb8 was new but does not seem as strong as the established 19..Na5. 23..Ne8? was too slow; Boleslavsky considered it to be the losing move. 33..Rf5 would have been better but would not have saved the game.

<xrt999: 34...Qe7 is a blunder.>

There is no defense to 35 Rxg7+.
