Mar-22-12  sevenseaman: < viking78>Nice. Too easy for you.
Mar-22-12  James D Flynn: 27.Rxe5 Bxe5 28.Rxd5 threatens Rd8# and h6 or h5 with double check winning the R on c8 or the Q on g7 for a R, thus forcing a K move after which White simply plays R or Qxe5 remaining a piece up with the Black K still in danger. If Black instead plays 27....g5 28.Qxf5 Rc1+ 29.Kg2 Bxe5 30.Rxd5 and the same threats remain. In either line Qb7 pinning the Ron d5 is simply answered by Qxe5.

  Oxspawn: I am allowing myself five minutes max away from some heavy editing to do this. So off the cuff…

27 RXR BXR
28 Rxd5 BxQ
29 Rd8 double check and mate

OK so there may be some alternatives for black but this is my solution so black cannot see them. Ginzburg is in a rush, just like me. He’s got a poem to write and he’s not sure how to spell his name either. Y Ginsburg? Why not Ginsberg?

  Oxspawn: Oh Yay! I can 'do' Thursday puzzles - at least part of the way! I'm with <pogotheclown> - either they are getting easier or I am getting better. Five minutes is up now.
Mar-22-12  5hrsolver: I like the puzzles up to thursday. Starting friday the waters get murkier.
Mar-22-12  cyclon: 27. Rxe5 Bxe5 ( -g5 28. Rexd5 threatening Rd8 dismate ) 28. Rxd5 wins at least Bishop. For the blink of an eye Qf4 covers c1, which suffice and Black should do something to prevent 29. Rd8 dismate.

Mar-22-12  BOSTER: This is the position couple moves before <POTD>.

Maybe somebody can explain me why black had to play 25...Nxe5, taking the bishop on e5 which is pinned, opening the diagonal a2-g8 for white bishop,where, btw, his own naked king, and opening the "d" file for white rook.

Maybe you understand, but I don't.

And after this ask himself who creates tactics possibilities in <CG POTD> the winner,or the loser.

Mar-22-12  Crispy Seagull: Very nice. Black has no idea that at the very least he's dropped his bishop. You've got to love the threat of a double check since you usually can't block it and the king will have to move. In this case it'd be mate, and a beautiful one at that.

  Once: This one is a real eye-opener. The power of the discovered/ double check is so much that white can afford to drop his queen to set it up. That took me by surprise.

Maybe that is a lesson for all of us. If we have a chance to set up a discovered attack we should be prepared to invest heavily for the privilege.

  Gilmoy: I enqueued my usual witty/snide comment, and finished reading p.3 to the bottom. En passant, I noticed:

<BOSTER: Maybe somebody can explain me why black had to play 25...Nxe5> We seize the same flaw, with divergent interpretations. My jape goes thus:

Black was so busy lemma-proving that the 4-on-3 at e5 "wins a pawn" -- that he forgot <what else> the Nc4 was doing. A piece has more than one job!!

He even played <18..Nc4> specifically to blockade the a2-f7 diagonal (and its finite extension, haha). But later, he forgot his own intent.

This is illuminating in revealing a possible category of misconception or flaw among chess players: something like <omission of label> in his mental protection-graph, forgetting to tag Nc4 with a <blockade-role>, which caused him to overestimate its mobility.

Possible fix: Add new mental tool of the <burning blinking red tag>, and when you move-to-blockade, mentally write the reason in <burning blinking red> font, affix to piece. So your graph becomes decorated along a new axis of richness. Later, whenever you think of moving a piece, hopefully the tag leaps out at you, and reminds you to prove a sub-lemma that violating this constraint is now-safe. (It's essentially the same as the memory sport technique of seeing 47 cards dealt face-up, and naming the 5 remaining cards, by mentally "mutilating" your mnemonic for each card, and then scanning your memory for the ones that aren't mutilated.)

Mar-22-12  LIFE Master AJ: A Rakhmanov vs Y Ginzburg, 2010.

Thursday; March 22nd, 2012.

White to move, 27. '?'

I found one idea, it looks pretty convincing.

For the first minute, (maybe the first couple of minutes or so), I was stumped. I went through a lot of different permutations ... I gave the first move an exclam, as it sets up the whole combination. (The first few times, I tried to do without it ...)

27.RxR/e5!, BxR/e5. (Hits the Queen of f4.)

At first I was going to play (28.) QxB/e5 and then RxP/d5, (and try to run down the BQ with the rogue WR on d5); but then I found something a lot better.

28.RxP/d5!

Black cannot check on c1, as the Queen covers that square. And BxQ is answered by Rd8#. (Double-check ... and mate!) I think Black is lost, the only (half-way) decent defence that I can find is to put the BK in the corner, [28....Kh8.] but this loses to 29.RxB/e5.

If there is something better than this, I will be terribly disappointed ... ... ...

Mar-22-12  LIFE Master AJ: Of course, my first instinct was to move the WQ on the second move of the combination, but this turns out to be a waste of time.
Mar-22-12  M.Hassan: "Medium" White to play 27.?
White is a pawn down.

It is obvious if Black Rook on e5 is left by itself, he is going to get the White Rook with a check. So, the best move would be 27.Rxe5

27.Rxe5 Bxe5
28.Rxd5! Kh8
<if ....Bxf4 29.Re8#>

29.Rxe5
Now White is a whole Bishop up. The game may continue longer but I guess it will be White who wins. Time to check.

Mar-22-12  Patriot: Black is up a pawn.

Black threatens 27...Rxe1+.

27.Rxe5 Bxe5 28.Rxd5 looks like it wins a lot of material. 28...Bxf4? 29.Rd8#. 28...Qf7 29.Rd8+ Rxd8 30.Bxf7+ Kxf7 31.Qxe5 . I'm not sure what else black can try.

Mar-22-12  Rosbach: Good mate combination. Didn't see it.

  DarthStapler: Got it
Mar-22-12  1stboard: Niffy combination.

Is black any better off playing 26 Bxe5 instead of the move he played ( 26 Rxe5 ) ???

Mar-23-12  dragon player: Strange puzzle today. 27.Bxd5+ looks logical, but an obvious move like that won't be the solution. Maybe this works:

27.Rxe5 Bxe5
28.Rxd5!

Black can't play 28...Bxf4 because 29.Rd8# is really mate.

28...Kf8
29.Rxe5

And white is a piece up.
I think this is it.

Time to check.

----------------

Yes I was right.

I'm one day too late, because when I wanted to check, my internet was out.

4/4 now and directly on to the friday puzzle.

Jan-18-14  dunamisvpm: In my humble opinion, it is not so much so about the puzzle trying to solve what is the best 27th move for white. But the greater question is, how come this Caro-Kann defense with this 4...Qxd5 variation for black and 7.Bc4 variation for white that leads white to win this game? In the database, 4...Qxd5 does give a bleak percentage win for black. GOD bless
