  johnlspouge: <CHESSTTCAMPS> gives a winning variation for my (3.3) 62Kc1. I only give a drawing variation, showing with minimum effort that White can obtain a draw.

It has been a week of interesting draws, but the knowledge (or at least the strong suspicion) that White wanted to draw made the puzzle today much easier.

Apr-19-09  butilikefur: Rb3+ Kxa2 Ra3+ (Kxa3 Qd3+ Qxd3 is stalemate) Kb2 (Kb1 Qd1+ Kb2 Qa1+ mate) Qb5+ Kc1 Qf1+ Kd2 Rd3+ Qxd3 Qe1+ Kxe1 is stalemate.

  agb2002: Black threatens 60... Qg4#, 60... Qg2#, 60... Qh1# and 60... Kxa2. The most forcing move is 60.Rxb3+ Kxa2 61.Ra3+:

A) 61... Kxa3 62.Qd3+ Qxd3 stalemate.

B) 61... Kb1 62.Qd1+ Rc1 (62... Kb2 63.Qa1#) 63.Qb3#.

C) 61... Kb2 62.Qb5+

C.1) 62... Kxa3 63.Qd3+ Qxd3 =.

C.2) 62... Qb4 63.Rxa5 followed by the exchange of queens and Rxh5 with a won endgame.

C.3) 62... Kc1

C.3.a) 63.Qf1+ Kd2 (63... Kb2 64.Qa1#) 64.Qg2+ (64.Rd3+ Qxd3 65.Qe1+ Kxe1 =) Qxg2+ 65.Kxg2 (threatening 66.Ra5 and 67.Rxh5) Rc5 66.Ra8 Ke3 67.Re8+ Kd5 68.Rg8 (threatens 69.Rg5) Rc7 69.Rg5 Rh7 70.Kf3 and White should win the endgame because the Black king is far from the pawn and his way back is cut by the white king and rook.

C.3.b) 63.Ra1+ Kd2 64.Qxa5+

C.3.b.i) 64... Ke2(3) 65.Re1+ + -.

C.3.b.ii) 64... Kd3 65.Rd1+ Kc4 (65... Ke2(3) 66.Re1+ + -) 66.Qa4+ + -.

C.3.b.iii) 64... Rc3 65.Ra2+ Kd1 (65... Kd3 66.Qd8+ Qd4 (66... Kc4 67.Ra4+ + -; 66... Ke3 67.Qd2+ Kf3 68.Qf2#) 67.Rd2+ + -) 66.Qa4+ (66.Qxc3 Qa1+ 67.Rh2 Qf1+ =) Qxa4 67.Rxa4 Rc5 (67... Ke2 68.Ra5 Kf2 69.Rf5+ and 70.Rxh5 + -) 68.Kg2 with a conclusion similar to C.3.a.

I haven't found anything better for White.

Apr-19-09  butilikefur: oops. Zatara above has already given my exact line.
Apr-19-09  cheeseplayer: 60. Rxb3+ Kxa2 (forced)

  agb2002: I made a curious mistake in Black's threat list: 60... Qg4+ is not mate, just leads to a won endgame after 61.Qxg4 hxg4+ 62.Kxg4 Kxa2 63.Rxb3 Kxb3 and the a pawn promotes.

<CHESSTTCAMPS: ... C.3.1 64...Ke3 65.Re1+ Re2 66.Qc3+ Qd3 67.Qxd3+ Kxd3 68.Rxe2 Kxe2 69.b4 wins> I missed 65... Re2. After 66.Qc3+ Black can play 66... Kf2 making things more complicated. Probably 66.Rxe2+ Kxe2 67.Qxh5+ is better but seems to be best 65.Qe1+ Re2 (otherwise the rook checks along the a file winning) 66.Ra3+ Kd4 67.Ra4+ Kd5 68.Rxe4 and wins.

Apr-19-09  TheChessGuy: This has been a pretty neat week for puzzles. It has taught me that GM Larry Evans was right when he said "Nobody ever drew or won by resigning."
Apr-19-09  goodevans: <cheeseplayer: 60. Rxb3+ Kxa2 (forced)

61. Qa4+ Qxa4 (forced)

62. Ra3+! take it or leave it! >

Ill take it, thankyou, with 62 ... Kxa3!

<... easiest sunday wohoo.>

As is so often the case with the weekend puzzles, the first move is easy to see, and sometimes (as today) the second as well. Unless you can see to the point where the smoke clears, so to speak, then you cant really say youve solved it.

Today I saw 60 Rxb3+ Kxa2 61 Ra3+ Kxa3 62 Qd3+ in less than 30 seconds, but try as I might I just couldnt find 61 ... Kb2 62 Qb5+. Dont know why, but alas no points for me today.

I looked at this one too - unfortunately 62...Kxa3 leaves white the legal move 63.g4, answered by 63...Qxg4#. The queen must be pulled to the 3rd rank to create the pin that makes the stalemate.

  Honza Cervenka: <al wazir> <I think 51. Rxd3 would have given white a winning game.> No, it doesn't give white a won ending and it even cannot save white from defeat here as after 51.Rxd3 Qxe3 52.Rxe3 Rc2 black wins white Pa2 and his Qs Pawns will be too quick for white after that.

Obviously I intended 69.g4 instead of b4 in this flawed line.

<I missed 65... Re2. After 66.Qc3+ Black can play 66... Kf2 making things more complicated. Probably 66.Rxe2+ Kxe2 67.Qxh5+ is better but seems to be best 65.Qe1+ Re2 (otherwise the rook checks along the a file winning) 66.Ra3+ Kd4 67.Ra4+ Kd5 68.Rxe4 and wins.>

Nice catch and a strong improvement with 65.Qe1+. Also, after 64...Kd3 64.Rd1+ Ke3, 65.Qe1+ is stronger than 65.Re1+ (on 65...Re2 66.Qg1+ wins; Kf3 66.Qh1+ wins)

The play with Q+R for both sides on an open board is reminiscent of (although less complex than) Fischer's analysis of Botvinnik-Fischer in My 60 Memorable Games.

  Honza Cervenka: Btw, despite of a bit odd finish of this game (by last move black makes a huge mistake blowing thus an utterly won game and white immediately resigns in a position where he can force draw by elegant combination) I have to say that it was excellent battle and that Rodriguez played it in great style.

  Jimfromprovidence: 59Rc3 is the winning move, correct?


click for larger view

If 60 Rxc3+, then 60bxc3 seems to create an unstoppable passed pawn. So, it looks like 60 Rd1 is forced to prevent Qh1#.

Now, if 60a4 (in order to keep his rook at c3), Im not sure what white can do.

Apr-19-09  JuarezB: Mr. Amador might be a great surprise on hearding "I resign". I feel like such position is not Insane. A draw can be found with no further thoughts.
Apr-19-09  TheaN: Damn. After my target of 15 minutes I gave up. I got the main line, with Kxa3 Qd3, but thought Rb3 was forced on Kb2 and couldn't find anything. I ditched Qb5 due to the 'simple' Qb4. Of course, Rxa5 might even be winning for White. Well, nice week, although I should have found this one.
Apr-19-09  WhiteRook48: white shouldn't have resigned. I thought White should play 60. Qa4+ thinking that white could do a stalemate trap, but I forgot the pawn on g3 could move

  dzechiel: <<dzechiel: Black threatens both 60...Qg4#>

You mean 'which is prevented by White's queen', right?>

Uh..., right! That's what I meant. Yeah, for sure.

Apr-19-09  eightbyeight: Does resigning actually count as a move? You don't move anything when you do it.
Apr-19-09  TheBish: W Wittmann vs A Rodriguez, 1980

White to play (60.?) "Insane" (4 stars)

Continuing with "Draw Week", since I can't find anything close to a winning try. Black's threats of both 60...Qg2# and Qh1# are hard to meet (insanely hard!), so White is looking for a way to give up both queen and rook, and a-pawn as well, while somehow diverting Black's queen to the 3rd rank, which would pin White's only remaining obstacle to stalemate, his mobile g-pawn.

Candidate moves: Rxb3+. This is the only starting move that makes sense, so the trick must be down the road.

60. Rb3+ Kxa2 61. Rf3!!

This blocks the queen's access to mates on g2 and h1, and acceptance of the rook puts Black's queen on the 3rd rank, which was one of our objectives. Now if

61...Qxf3 62. Qa4+ Kb2 (if 62...Qa3 63. Qxc2+ should draw, or 62...Kb1 63. Qa1+! Kxa1 is stalemate) 63. Qa3+! (or Qb3+!) and now either capture of the queen is stalemate, and refusal lead to Black's loss of his own queen.

If Black declines the rook on move 61, than after 60. Rxb3+ Kxa2 61. Rf3 a4, I believe White can draw with 62. Qf5!, eliminating the h5 pawn, i.e. 62...Qxf5 63. Rxf5 a3 64. Rxh5 Kb1 65. Ra5 and it seems that White pawns will neutralize Black's rook after White trades his own rook after the a-pawn queens. Or if 61...Qe2, 62. Qf7+ and 63. Qxh5 eliminates the mate threat and should draw.

Let's see how close I came.

Apr-19-09  RandomVisitor: 47.Qe3 and white is still in the game.

I guess black wins because he keeps both queenside ♙s and blocks the promotion of white's f-♙ with his ♖. Thanks.

  offramp: Very tricky. The difficulty is in forcing the black queen to the 3rd rank so as to pin the g-pawn.
