Kibitzer's Corner

Sep-23-14  Moszkowski012273: Agreed.... The puzzle should of been from black to play on move 34. Pretty sure this is a mistake.
Sep-23-14  morfishine: <35...Ng3+> wins neatly and instantly after 36.Rxg3 fxg3

The main threat is simply 37...g2# and curiously White cannot defend g2 properly, for example: 37.Rd2 g2+ 38.Rxg2 Qxe1 OR 37.Qf1/e2/d2 g2+ 38.Qxg2 Rxg2


<plumbst> Yes, 34...Bg2+ was very nice and what drove this combination


Sep-23-14  jvv: The problem is that on move 34 almost everything wins, Qxe1, Qg5, Qf6, Qe7. There is no need for Bg2.
Sep-23-14  cocker: Hard for an 'easy' one
Sep-23-14  Nick46: <cocker: Hard for an 'easy' one> I beg to differ; apart from 35 ... Ng3+ there wasn't very much else on offer and the rest followed automatically.
Sep-23-14  stacase: 35 ... Ng3+ cried out to be played, it just took a little checking to make sure there wasn't something wrong with it.
Sep-23-14  cocker: <Nick46> I saw through to the final position, but at first glance didn't realise how deadly it is for White.
Sep-23-14  zb2cr: 35. ... Ng3+! does it.

  Once: This is another of those puzzles where it is not enough to win the enemy queen - we need to count how many of the magnificent seven are left alive at the end of the battle with the bandeets.

Only then can we decide that the farmers have won. The farmers always win.

Here's what at first seems to be the main line:

35... Ng3+ 36. Rxg3 fxg3

Now white has to do something about g2#. He has to put his queen on a square where it can cover g2 - say e2, d2 of f1. It doesn't matter which.

Then we get 37. Qe2 (say) g2+ 38. Qxg2 Rxg2 39. Kxg2 Rg8+ 40. Kf1

Time to take stock. There is no immediate mate but black has queen for two pieces plus a pawn. Possibly more importantly, black doesn't have an obvious attack and his weakling pawns make it difficult to construct a fortress. This is not a time to start digging ditches around the peasant village.

With that in mind, we could (and probably should) rewind back to 35...Ng3+ to see if we can improve on white's defence.

Fritzie finds the odd-looking 36. Qxg3 fxg3 37. Ne2 Rag8 38. Be3.

Well, if we are going to be forced to give our queen away, why not do it immediately? This doesn't save white - not by a long way - but it does hold out the possibility of digging a trench and hiding in it.

Interesting. Not what I was expecting from a Tuesday, but interesting all the same.

Sep-23-14  morfishine: Heinz ends up in a pickle, failing to ketchup against the attack that Black mustard
Sep-23-14  patzer2: Got 35...Ng3+! for my Tuesday puzzle solution, seeing 36. Rxg3 fxg3 37. Qe2 g2+ 38. Qxg2 Rxg2 .

However, it took me a while because I kept looking at the difficulties of 35...Rxg2?? 36. Kxg2?? . Then finally after a few minutes it dawned on me that 35...Rxg2?? loses outright to 36. Qxh4 .

Lesson learned: Look for obvious threats before analyzing anything in depth.

Sep-23-14  Ratt Boy: <morfishine>: Ugh.

(Thank you.)

  Penguincw: I got 35...Ng3+ 36.Rxg3 hxg3, but the followup is kinda hard to calculate.
Premium Chessgames Member
  Fusilli: <morfishine: Heinz ends up in a pickle, failing to ketchup against the attack that Black mustard> Wow, someone's muse woke up early today! ;)

<plumbst: Hmm, 34...Bg2+! seems more like the puzzle..although I guess it might be for a slightly harder day.> My thought as well when I looked at the whole game. Maybe the computer found a better move?

Premium Chessgames Member
  Fusilli: <Follow up>. Well, yeah, <Ivy> is right. 34...Bg2+ works as a puzzle for "black to play and win in the fanciest way", but if it's "black to play and win", there are various choices.
Premium Chessgames Member
  Bubo bubo: 35...Ng3+ 36.Rxg3 (or 36.Qxg3 fxg3 losing the queen with Black's attack still going on) fxg3 threatening g2#.

White cannot give his king more room (37.B~ Qxh2# or 37.h3 Qxh3+ and mate next move), and fleeing is also hopeless: 37.Kg2 gxh2+ 38.Kf1 hxg1Q+ (or 38.Kh1 hxg1Q# with a rare double-check by two queens) 39.Ke2 Rg2+ 40.Kd3 Qhxe1, and White is down tons of material.

Therefore White has to guard g2, but this loses the queen: 37.Rd2 g2+ 38.Rxg2 Qxe1 or 37.Qf1 g2+ 38.Qxg2 Rxg2 (slightly better, but still not fun).

Premium Chessgames Member
  agb2002: Black is one bishop down.

White threatens 36.Qxh4.

The obvious 35... Ng3+ 36.Rxg3 fxg3 seems to win:

A) 37.Rd2 g2+ 38.Rxg2 Qxe1, etc.

B) 37.Be3 Qxh2#.

C) 37.Qf1 g2+ 38.Qxg2 Rxg2, etc.

Sep-23-14  kevin86: black's brutal attack will win the queen OR more.
Sep-23-14  BOSTER: This is the pos. Black to play 28...

According to Nunn an imagination is required to play chess. If this is correct , I'd say black queen had no right to retreat.

Premium Chessgames Member
  Once: <BOSTER> So what would you like to do instead?

White has a strong grip on the centre with doubled rooks on the d file. Black's main chance lies with a kingside attack to make use of his extra space on that wing.

So the last thing that black wants to do is to allow the queens to be exchanged. And that means that a queen retreat is one of the <best> things he can do in this position.

I could make half a case for 28...Ng3+ if it worked. But here it seems a tad too early. Fritzie confirms that the best move for black is the queen retreat 28...Qg5, with an evaluation of over -3.7. 28...Ng3+ is not bad at -1.9.

Fritz does not score 28...Qe7 so highly, but I think that Nunn is playing a clever game. He is slowly rearranging his forces on the kingside so that the attack, when it comes, is irresistible. The point of Qe7 is that it allows Bf6-Bh4-Qg5. The queen returns to the kingside with a vengeance.

That's what Nunn meant about needing imagination to play chess. Sometimes you need to regroup in order to come back in a more deadly way.

Sep-23-14  BOSTER: < Once: 28...Ng3 is not bad at -1,9>.

Thanks for evaluation.
I guess that -1,9 it is enough to win.

Sep-23-14  kyg16: Dear Chessgames users. I want to use this place -which, being puzzle of the day has many visitors- to raise awareness about how Chessgames staff is beginning (again!) to repeat the "Quotes of the Day". This had happened in the past and in that opportunity I wanted to complain, but luckily it was only a couple of weeks of repeating old quotes and then the new ones started to appear again.

Now this time I have decided to expose this situation as soon as it began, and when I read the Torre quote about Fischer's daughter I flew to write this post. you have an amazing website, you do a great job, but WE ENJOY READING NEW QUOTES EVERY DAY. You can't take us for fools.

  OhioChessFan: I recommend each member say something interesting about chess to give cg.c a new supply of quotes.
Sep-23-14  thegoodanarchist: It all went wrong - horribly wrong - for White.
Premium Chessgames Member
  Once: <BOSTER: I guess that -1,9 it is enough to win.>

Usually. But -3.7 for a queen retreat is stronger.
