Aug-30-12  zb2cr: Found this one rather quickly (for a Thursday).
Aug-30-12  LoveThatJoker: <David2009> 30. Qb8+ Bf8 31. Kh1 Kg7 32. Rd1 Be7 33. Qc7 Ne6 34. Qxd6 Bxd6 35. Rxd6 produces an easy win against Crafty.

  paulalbert: Totally missed: Looked at Qe7 and Rxa7, but didn't combine the two ideas to see that's how to make Qe7 work.

  agb2002: White has a rook for a knight.

Black threatens 28... Rxg5, 28... Rxd5 and 28... Qxd6.

The weak spot f7, the open e-file and the necessary support of the advanced d-pawn suggest 28.Qe7, threatening mate in two (28.Qxf7+ Kh8 29.Qg8#) and to push the d-pawn:

A) 28... Rxe7 29.dxe7

A.1) 29... Qb8 30.Rfe1 Qe8 31.Rxa7 Ne6 32.Ra8 Nc7 33.Rxe8+ Nxe8 34.Bc6 + -.

A.2) 29... Ne2+ 30.Kh1 Qb8 31.Bc6 + -.

B) 28... Rxd5 29.Rxa7

B.1) 29... Rf5 30.Ra8+ and mate in two.

B.2) 29... Ne6 30.Qxf7+ Kh8 31.Ra8+ B(N)f8 32.Rxf8+ N(B)xf8 33.Qxf8#.

B.3) 29... Qxa7 30.Qxa7 Rxd6 31.Qb8+ Bf8 32.Qxb5 + - [Q+P vs B+N].

C) 28... Rf5 29.Rxa7 and the threat 30.Qxf7+ will cost Black more material.

D) 28... Ne6 29.Rxa7 is similar to previous lines.

Aug-30-12  MATTYMONKEES: My solution - because I am a beginner and think like an amateur:

28. Bxf7+ Kxf7 29. Qe7+ Rxe7 30. dxe7 Qb8 31. Rfe1 Bf8 32. e8=Q Qxe8 33. Rxe8 Ne6

This is probably not the ideal sequence for White, but at the end, White is significantly ahead. Thoughts?

Aug-30-12  JRMenezes: This puzzle should be classified as "insane". In fact I have a suggestion, why don't they let the kikibiters to vote on the difficulty levels?
Aug-30-12  Blunderdome: I looked at Qe7 but didn't see Rxa7 as a response to Rxd5. Tried to make Bxf7, Ra6, f5 etc. work... nothing.
Premium Chessgames Member
  Once: <MATTYMONKEES> 30...Kxe7 spoils the fun I'm afraid. Black has queen, knight and bishop against two rooks, which ought to be a safe black win.
Premium Chessgames Member
  kevin86: White will win the queen AND queen himself! or mate!
Aug-30-12  sevenseaman: Had a bad ISP today whole day. I was about to post when it collapsed and I lost my write up too. Briefly this was the gist.

28. Qe7 Rxe7(if Rxd5 29. Rxa7 is worse)29. dxe7 Qb8 30. Rfe1 Qe8 31. Rxa7 and 32. Ra8 wins.

Aug-30-12  MATTYMONKEES: <Once> You are indeed correct. And this is why I'm not very good at Chess.
Premium Chessgames Member
  Once: <MATTYMONKEES> Not yet, my friend, not yet. I happen to believe that anyone who can drive a car, operate a television remote control, send an email and either get themselves into - or someone else out of - a brassiere can learn to become a decent chess player.
Aug-30-12  Jambow: Ok missed Tuesday yet I saw this in seconds as the idea of sacking the queen to advance the passer was begging to be looked at, especially with two rooks to drive the nail in. GG and puzzle.
Aug-30-12  rudiment: Failure. I saw that the creation of a threat on f7 would be a nice escape from having the Q en prise but overlooked Qe7.

The shimmy that pawn makes over to the e-file is so simple when you see it! First puzzle in months after a moving-country-related hiatus so I'm not beating myself up.

Aug-30-12  David2009: A Jankovic vs V Nedilko, 2012 postscript: <LoveThatJoker: <David2009> 30. Qb8+ Bf8 31. Kh1 Kg7 32. Rd1 Be7 33. Qc7 Ne6 34. Qxd6 Bxd6 35. Rxd6 produces an easy win against Crafty.>

Indeed it does, and thanks for posting the variation. I think it starts at move 31 not 30, thus (after 28...Rxd5 29.Rxa7 Qxa7 30.Qxa7 Rxd6) 31.Qb8+ Bf8 32.Kh1 Kg7 33.Rd1 Be7 34.Qc7 Ne6 35.Qxd6 Bxd6 36.Rxd6. However, 32.Kh1 is an extraordinarily bold and counter-intuitive move to find (it creates back rank mate self-threats). An alternative win against Crafty EGT is found by using your idea of a pin on the d file to exchange Rooks. Starting from the position at move 31,

The following variation beats the EGT varying from your win at move 31 31.Re1 (activating the Rook) Bf8 32.Kf1 Rd8 33.Rd1 Nc6 34.Qa1 Nd4? This move is a blunder by Crafty: exchange of Rooks is essential for Black since the Q vs N+B endimng will be very difficult for White to win. 35.Qa5 (of course) Nc6 (what else?) 36.Qxd8 Nxd8 37.Rxd8 with an elementary win the exchange ahead: Black has no defense against transposition to a won K&P ending.

Much tougher is 34...Rxd1+ with an extremely difficult win. Here's a further Craft EGT link to explore this variation:

As a general comment, one can learn a great deal from Crafty EGT's approach of building defensive fortresses when material down: many a half point can potentially be saved in such fashion. No time for more tonight.

Aug-30-12  fokers13: Got it within seconds,relatively easy for a Thursday.

Looking forward to tomorrow.

Aug-30-12  James D Flynn: Material is equal but Whites Q, B, and P on d6 are threatened, he cannot protect them all .His next move must be a tactical shot: candidates Qe7,Rfe1. 28.Qe7 Rxd5(if Rxe7 29.dxe7 Qb8 30.Rfe1 Ne6(if Qe8 31.Rxa7 Bf8(ifNc6 32.Bxc6 Qxc6 33.d8=Q+ Qxe8 34.Rxe8+ Bf8 35.Raa8 wins)32.Ra8 Qxa8 33.Rxa8 wins) 31.Rxe5 fxe6 32.Bxe6+ Kh8 33.Bf7 any 34.e8=Q+ Qxe8 35.Bxe8 wins)29.Rxa7 Rf5 30.Ra8+ Bf8 31.Qxf8# 28.Rfe1 Rxg5 29.Bxf7+ Kxf7 30.Re7+ Kf6 and Black wins..
Aug-30-12  Patriot: <David2009> You are right about the position in the Crafty link above. It is a very difficult win. After a draw and a loss, I finally won but it took many moves. I snagged a pawn and tried to put it in some sort of zugzwang. It moved the bishop to an unprotected square and I was able to zigzag my queen while checking and then won the bishop. After that, it still wasn't easy to win vs. the knight. I was able to slowly corral the king to the edge but was careful the whole time not to fall into a royal fork by keeping the queen at a safe distance.
Aug-30-12  Moonwalker: Too hard for me.. Not having a good week :/
Aug-30-12  LoveThatJoker: <David2009 & Patriot> Thanks for the reply, guys! I'm glad we all were able to defeat Crafty!


Aug-30-12  Abdel Irada: <JRMenezes: This puzzle should be classified as "insane". In fact I have a suggestion, why don't they let the kikibiters to vote on the difficulty levels?>

Although I disagree with you about the difficulty of this puzzle, your idea is an interesting one: Trust in the wisdom of the crowd to determine how hard the puzzles really are for the members of the crowd to solve.

What isn't so clear is how this would be implemented, or if indeed it is possible.

(Just one objection: I have never in my life bitten a kiki.)

  gawain: I did (eventually) see that 28 Qe7 would get the white pawn in a more promising queening file. But I did not quite see how to force matters to a conclusion after 28...Rxe7 29 dxe7 Qb8.
Aug-30-12  Tiggler: This seems like the first time this week when everyone agrees: 1. Who is winning, 2. What the winning first move is, 3. What is the best defense, 4. What is the second best defense, and 5. How to continue, in each case.
Aug-31-12  psmith: I got this one pretty quickly.

BUT: this site relies on java. And I recently upgraded my java, only to discover this morning:

Thought the rest of you would like to know.
