Aug-20-13  Moonwalker: Wonder what the difficulty rating would have been if the puzzle started two moves earlier at 23. ...?
Aug-20-13  engmaged: <torro: 23... Bxb2! is very beautiful> agree 23...Bxb2 24.Kxb2 Rc3 25.Rd3 Qa3+ 26.Kg1 Ra6
Aug-20-13  TheaN: Tuesday 20 August 2013

<25....?>

Wait, what? Tuesday queen sac.... tsck CG, keep yourself to the theme.

Black's dominant position decides after <25....Qxa2+ 26.Kxa2 (Kc1 Qa1#) Ra6+ 27.Kb3 (Kb1 Ra1#) Ra3# 0-1>.

I have no outside-of-the-box analysis for this one, and many have done so on white's Qe6+ already. Guess that's basically it.

Aug-20-13  agb2002: Black has a bishop and a pawn for a knight.

White threatens 26.Qe6+ (26.Qxe7 Rb7 protects the second rank) 26... Kh8 (26... Kf8 27.Qf7#; 26... Kg7 27.Qf7+ and 28.Qxh7#) 27.h5.

However, Black can deliver mate in three with 25... Qxa2+ 26.Kxa2 (26.Kc1 Qa1#) 26... Ra6+ 27.Kb3 (27.Kb1 Ra1#) 27... Ra3#.

Aug-20-13  engmaged: Is there a way I can copy some moves sequence from the board? I can "bring up branch" or "delete a branch"... Can I "Copy a branch"?
Aug-20-13  Oxspawn: This looks easy but I struggled strangely with the easiest option. The problem for black is that if white can play Qe6+, black defences collapse and (I think) white can mate. So black's moves have all to be forcing. The first option came very quickly
25. ...........Qxa2
26. Kxh2 Ra6+
27. Kb1 Ra1++
But for some reason I got stuck after
25. ………. Qxa2
26. Kc1
I am ashamed to say that it took me ten minutes to see that 26. …. Qa1 is mate. I was all for sacrificing the queen (again) on c2 and then using Bd4 for a discovered check to swap queens. This would have left black with a rook and a two pawn advantage (one of them advanced) while white was left with a rook and a knight and would probably win. So much for Monday/Tuesday being easy (although yesterday hardly required anything more than knowing the moves). It goes to show that visualising a position is much harder than seeing what to do after moves have been physically made. I will not 'diss' Tuesday in future. Easy is as easy does.
Aug-20-13  Abdel Irada: <PB: When your own king is expose, quiet attacking moves may not be forceful enough.>

Although in this case White wins only if Black plays a weakening move such as 25. ...Qa3? As long as the queen remains on a6, defending the rook on c8, White does not appear to have anything.

Aug-20-13  bubuli55: Another Q sac. 25... b3 also wins but we won't be writing about it. Do we?
Aug-20-13  mistreaver: Tuesday. Black to play. Easy. 25.?
This one is realy easy.
25... Qxa2+
26 Kxa2 (26 Kc1 Qa1 mate)
26... Ra6+
27 Kb1 Ra1 mate
Aug-20-13  GilesFarnaby: Amazing to see how the famous Kh1 in the Dragon that Carlsen invented was already played in 1964, albeit with a different success rate.
Aug-20-13  zb2cr: A Queen sacrifice for Tuesday. 25. Qxa2+; 26. Kxa2 (else mate by ... Qa1#), Ra6+; 27. Kb1, Ra1#. Or if 27. Kb3, Ra3#.

  gawain: I considered ...Qa3 first but then I realized that White has a dangerous-looking attack going. I thought maybe B had better make forcing moves.

Then it is easy to see that ...Qxa2+ is the winning move. Whether White captures or tries to run he is mated soon. The mate with the rook at a1 is nice but I like the way that the c-file rook comes into play by covering the escape square c4 in the variation 25...Qxa2+ 26 Kxa2 Ra6+ 27 Kb3 Ra3#

  LIFE Master AJ: 25...QxP/a2+! followed by ... Ra6+ and ...Ra1#.
Aug-20-13  James D Flynn: Black is a pawn up and both sides have mating threats but Black’s comes with a simple sequence of checks: 25:…..Qxa2+ 26.Kxa2 Ra6+ 27.Kb3(if Kb1 Ra1#) Ra3#.
Aug-20-13  belgradegambit: On a Monday or a Tuesday, don't analyse, just sac the queen!
Aug-20-13  Alex56171: 25...Qxa2+ 26.Kxa2 (Kc1 Qa1#) Ra6+ 27.Kb3 (Kb1 Ra1#) Ra3#
Aug-20-13  M.Hassan: "Easy"
Black to play 25...?
Black is a pawn up.

25........Qxa2+
26.Kxa2 Ra6+
27.Kb1 Ra1#
If the King moves to b3, same result is obtained:

27.Kb3 Ra3#

Aug-20-13  Chessman1504: The sacrifice on a2 reminds me of the first winning middlegame position in Capablanca's "Chess Fundamentals."
Aug-20-13  JoergWalter: <chessman1504>example 11, p.19 in his book.
Aug-20-13  GilesFarnaby: <Dionysius1: Hi <GilesFarnaby> Do you mean Kb1?>

I totally do, sorry for the confusion.

Aug-20-13  JustAnotherPatzer: maybe they'll do the treble tomorrow
Aug-20-13  Doniez: Queen takes a2 and the White King must take a2. The Rook slides on the a-file and check. The King escapes along the 1st rank but the Rook keeps on chasing and mates.
Aug-20-13  bubuli55: < Abdel Irada: <PB: When your own king is expose, quiet attacking moves may not be forceful enough.> Although in this case White wins only if Black plays a weakening move such as 25. ...Qa3?

A variant ...

25... e5

26. ~ Qa3

And Black wins :)

Aug-21-13  kevin86: White will be mated,either on b1 OR b3
