White in 3

May-16-11  David2009: R Primavera vs Jansa, 1976 21 Qc3 - unusually neat finish! <sevenseaman:> Lovely puzzle in Akopian vs Kasparov, 1995 - and thanks for posting the solution!

In your puzzle today, imagine that the board is turned round (so Black pawns are moving UP the board) and you have mate in 4.

1.Bf6 gxf6 2.Kf8 f5 3.Nf7#


1.Nb4 Kb1 2.Nc3+ Ka1 3.Kc2 b1=Q+ 4.Nxb1#.

May-16-11  Intrepid Spiff: <dzechiel: ...and black goes up a piece and a pawn. Very cute.>

Black goes up *two* pieces and a pawn!

May-16-11  sevenseaman: <agb2002> Well done. it looked tough to me. The clue hidden in the anagram was;

A moan may not = a man too many

You didn't need it though.

May-16-11  gofer: A nice little combo starting with

<21 ... Qxc3>

The threats are <22 Qxc2#> and <22 Na2+ Kb1 23 Qxb2#>, but unfortunately for white

a) the black queen is immune from capture by the pawn 22 bxc3 Na2#

b) the white king cannot run from danger 22 Kb1 Nd3 23 Nc4 Rxb2+ 24 Ka1 Qxc4 25 any move Qa2#

So all that white is left with is taking the queen with its own queen

<22 Qxc3 Na2+>
<23 Kb1 Nxc3+>
<24 Ka1 Nxe2>
<25 Re1 Nxf4>

Black has won two minor pieces and a pawn and still has a half open file to white's stranded king... ... time for white to go quietly...

May-16-11  CHESSTTCAMPS: In this open middlegame position, the kings are castled on opposite wings and material is even, but only black has the advantage of owning semi-open files on the attacking wing. This is decisively exploited with 21... Qxc3! 22.Qxc3 (bc Na2#; otherwise black mates within two on b2 or c2) Na2+ 23.Kb1 Nxc3+ 24.Ka1 Nxe2 winning two minor pieces.

Time to see how white lost the initiative so early.

May-16-11  Gilmoy: Nella penombra dolce della sera <passa la primavera>

The finish reminds me of the Gold Pieces Game S Levitsky vs Marshall, 1912, with the N cavorting in front of a pinned pawn to recover the Q and collect more loot.

May-16-11  alachabre: Monday, obligitory queen-sac day. Well, let's see.

21. ... Qxc3
22. Qxc3? Na2+
23. Kb1 Nxc3+
24. Kc1 Nxd1, this continuation nets a full rook.

And as I gave 22. Qxc3 a question mark,

22. bxc3?? Na2#, so perhaps

22. Nb3 is best?

Seems a bit complex for Monday, so maybe I missed it.

May-16-11  Beancounter: Just about my level - Qxc3
May-16-11  patzer2: The dual threat of mate or a Knight Fork winning decisive material justifies the Queen sham sacrifice 21...Qxc3! and solves today's Monday puzzle.
May-16-11  Patriot: <dzechiel> pretty much summed up how my thought process went, although in the line <22...Na2+ 23 Kb1 Nxc3+ 24 Ka1 Nxe2 25 Rg3 Nxf4> you may as well snap off the rook on g3.

<alachabre> <22. Nb3 is best? Seems a bit complex for Monday, so maybe I missed it.> It might be a little more than a Monday problem but it looks to me you solved it.

May-16-11  SuperPatzer77: <<alachabre>: 22. Nb3 is best?>

<alachabre> 22. Nb3 Qxc2# 0-1

  kevin86: The queen can be taken an extreme cost.

22 bxc3 ♘a2# or

22 ♕xc3 ♘a2+ 23 ♔b1 ♘xc3+ ♔ moves ♘xd1 winning...

May-16-11  psmith: I bet I would have missed this in a game. In a puzzle, it was easy.
May-16-11  DarthStapler: Got it easily
May-16-11  DarthStapler: I think 24... Nxe2 followed by Nxf4 is better than 24... Nxd1
May-16-11  castle dweller: <sevenseaman: Elementary, Mr Watson! (Clue; 'A moan may not' = another 4-word anagram.)mate in 3>

Nice one! Thinking it was the knight that had to get things started (due to the pin), I could only find mate in about 6-7 moves for white, beginning with N-f5. Finally reviewed everything - and saw the B sacrifice that got things started. This one was like a tuesday/wednesday for me.

May-16-11  alachabre: Revisiting the puzzle, with a little more time to spend. I read a couple of comments talking about a mate in three, and while I don't see that (at least just yet), I do see a bit more murderous of an attack after:

21. ... Qxc3
22. Qxc3 Na2+
23. Kb1 Nxc3+

and if

24. Kc1 Nxe2+ nabs an extra piece in comparison with my previous calculation. So,

24. Ka1 Nxd1 and up a full rook as before.

But I don't see a mate in three, and as it's tough to abandon a line that is a possible mate in two and at the very least wins a whole rook, I'll leave it at that. And oh by the way, my hasty thought of 22. Nb3 is pretty terrible.

  eternaloptimist: I solved this in less than 30 seconds. ♕ & ♖ sacs on c3 in the Sicilian occur pretty often. I remembered this recurring theme shortly after I started trying to solve this puzzle. GM Jansa cooked Primavera like a bowl of pasta primavera!
May-16-11  WhiteRook48: I have seen this before. Gotten in 6 seconds. 21...Qxc3! 22 Qxc3 Na2+ 23 Kb1 Nxc3+ if 22 bxc3 Na2# of course
May-16-11  stst: 21...QxN
22.QxQ (if PxQ, 23.Na2#) Na2+ <Rc8 may also be considered.> 23.Kb1 NxQ+
24.Ka1 (avoid another check) NxB without losing the N, or NxR also gaining in exchange. Either way, W loses heavy material

  agb2002: Thank you <sevenseaman>, I didn't notice the clue, just focused on the diagram.
May-17-11  mindfreakkk: Qc7 is wrong
