Mar-29-12  Patriot: Material is even.

I think I finally see it. 19...Bc4 is easy enough to find, attempting to remove the queen's defense on d1. But the follow-up was not.

20.Qxc4?? Rd1+ 21.Bxd1 Rxd1+ and mates.

20.Qe1 Bf1! and white probably resigns. 21.Qxf1 Nxg3+ 22.Rxg3 (forced) Qxf1+ 23.Rg1 Qxg1#

Mar-29-12  sevenseaman: The kind of plums we let go;

White.

<Patriot> <But the follow-up was not>.

21...Bf1 wasn't easy to find; after that its 'autopilot'.

Mar-29-12  Limpin Kt: <sevenseaman> 1Bf7 kf7 2.Ne5 and 1Rd7 wins. In potd i saw 19...Bc4 but after 20.Qe1 failed to visualize 20.:.Bf1! No credits today :(
Mar-29-12  CHESSTTCAMPS: How did white get into such a miserable defensive position so early? Material is even, but all black pieces are actively deployed, while 3 white pieces languish on their original queenside squares. It's obvious that white's Q+Rg2 are overmatched by black's 6 active pieces; both of these white major pieces are overloaded. The weak back rank suggests diverting the white queen from its defensive post.

19... Bc4! does the trick:

A) 20.Qxc4 Rd1+ 21.Bxd1 Rxd1+ 22.Rg1 Nxg3#

B) 20.Qe1 Bf1!! 21.Qxf1 (Rg1 Bxg1 22.Kxg1 Qg2#) Nxg3+ 22.Rxg3 Qxf1+ 23.Rg1 Qxg1#

C) 20.Qd2 Nxg3+! 21.Rxg3 Qf1+ 22.Rg1 Qxg1#

D) 20.Bd3 Bxd3 21.Q moves Bf1! again finishes quickly .

Most likely, the game went into B and white resigned at move 21.

  Penguincw: Some how, I managed to calculated the "long variation". I'm 3.5/4 this week.
Mar-29-12  En prise: Oxspawn good job in getting the puzzle correct.
A) study good opening fundamentals. Choose one or two openings for white and black. Play them and know them as best you can. That should help you to come out of the opening at least equal. You can go on from there. B) That's the whole point. OTB there IS nobody looking over your shoulder to tell you when there's a combination ,when the game is at a critical stage etc. Those are two reasons that all of us here find chess to be such a fantastic fascinating game (or sport).
Mar-29-12  sevenseaman: There are pointers in the position that you need to play carefully. It only looks a sitter.

I warned you there was a decoy. You gotta do one of them again.

Mar-29-12  VincentL: "Medium".

Another back rank theme today.

Black has many pieces in the attack; the question is how to divert white´s Q + R so that they cannot defend key squares.

I am looking at 19.....Bc4. Now if 20. Qxc4 Rd1+ 21. Bxd1 Rxd1+ and mate follows (22. Qf1 Rxf1+ 23. Rg1 Rxg1#)

What other defensive options does white have?

20. Qe1. Here I think 20.....Bf1 !. Now if 21. Qxb1 Ng3+ and the white queen is lost 22. Rxg3 Qxf1+, or 22. Kg1 Nxf1

Black is threatening 22....Qf2#, and if white moves his queen to the second rank to defend f2, it will be immediately captured (Rxd2, Bxe2 or Bxf2).

I think this is the solution.

Let´s check.

Mar-29-12  Memethecat: 19...Bc4!

If the sac is accepted =

20Qxc4 Rd1+ 21Bxd1 Rxd1+ 22Qf1 Rxf1+ 23Rg1 Nxg3#

If refused (more likely) =

20Qe1 Bf1¹ 21Qxf1 Nxg3+ 22Rxg3 Qxf1+ 23Rg1 Qxg1#

¹! threatens mate

********

Mar-29-12  TheaN: Thursday 29 March 2012

<19....?>

Material: even

Candidates: Nxg3†, Qxg2†, Rd1, Rd2, <[Bc4]>

In this kind of positions the attacking player does good to play well thought over reinforcing moves. They may be combinations, but being too agressive may backfire where it was not at all necessary.

Contradiction, I'd say. Last Thursday I lost a game where I was completely winning even without pushing my opponent's castled wing, and gave away the game being way too agressive. Yeah, I'm back and immediately you get my frustrating experiences to endure. Enjoy. Ah well, back to this one.

Many moves can do Black apart, considering he's so overwhelming White even without doing anything, he should be careful. One safe reloading move is the destructive:

<19....Bc5!> with the point being 20.Qxc5 Rd1† 21.Bxd1 Rxd1† 22.Qf1 Rxf1† 23.Rg1 Nxg3‡ 0-1, which on its own is a neat mate. Given this impossible move however, the White queen is very exposed, the Black rooks down the d-file, and the bishops scope both a6-f1 and a7-g1. This leaves White with the plain losing 20.Bd3 Bxd3, or:

<20.Qe1> this seems to hold. d1 still protected, g3 protected anew, g2 needed no protection. Hm. g2 needed no protection. We can make it need protection, of course.

<20....Bf1!> thoughts like the above lead to moves like this. When I saw Bc4, Bf1 was already clear. White is ill-fated to try 21.Qxf1 Nxg3† 22.Rxg3 Qxf1† . Alternatives however, are not readily available. Qxg2‡ has to be avoided. Only the rook can move, and the only reasonable placement seems to be:

<21.Re2> but White is still done after:

<21....Bxe2 > the bishop is immune due to Nxg3†, similar after 21.Rd2 Rxd2 and it's over.

  kevin86: This was a very subtle puzzle:a combination of tactics is required:

the decoy
The back row attack
the attack from behind,
the pin

not bad,eh?

Mar-29-12  David2009: J Whitehead vs Biyiasas, 1977 Black 19?

A baffling position - with level material however did White fall so far behind in development? Black wins quickly (I think) starting 19...Bc4 20.Qe1 (to protect d1 and g3: 20.Qxc4? allows Rd1+ 21.Bxd1 Rxd1+ 22.Rg1 Nxg3#) 22...Bf1! (threatening 23...Qxf2#: 23 Rg1 fails to Bxg1 with the same threat) 23. Qxf1 Nxg3+ 24.Rxg3 Qxf1+ 25.Rg1 Qxg1#. Even trying to give up Q for B with 20.Nd2 Bxe2 fails since 21 Rxe2 runs into Nxg3+ etc. Time to check:
====
Got it: 1/4 this week. <...however did White fall so far behind in development?> 13.Kh1 began the disaster: instead 13.Nd2 to be followed by Nf3 looks fine (I haven't checked with an engine). Here's the position colours reversed one move before the final disaster:

Mar-29-12  LivBlockade: Going back a couple of moves before the puzzle:


click for larger view

(position after 17. Rg1)

I'm sure in a game most of us would have played 17...Bxg1 rather than 17...Rd7. I wonder how much Biyiasas saw at that stage.

Mar-29-12  cyclon: 19. -Qxh2+ seems to be good ENOUGH, since - for example 19. -Bc4 20. Qe1 holds at least for the moment, but Black has pressure. After ( 19. -Qxh2+ ) 20. Kxh2 Nxg3+ 21. Kg2 Nxe2 the Bc1 is threatened so Black has a pawn and better game. Perhaps there's something more glorious.
Mar-29-12  cyclon: Yes, there was that glorious! Now it's easy to say (afterwards) that I'm a blind - but I didn't see that 20. -Bf1!! though I studied 19. -Bc4.

  Oxspawn: <en prise> <Choose one or two openings for white and black. Play them and know them as best you can. That should help you to come out of the opening at least equal.>

Yes I play a limited number of openings until I am bored silly with them, but my opponents don't cooperate and continually play moves I did not want them to play. Obviously this is very poor chess etiquette on their part, but I find that ignoring what they are doing and carrying on with my plan usually ends in disaster, while responding to what they are doing ends in the same place, only bloodier and sooner. But I am sure your approach is sound.

Mar-29-12  M.Hassan: <LivBlackade: I'm sure in the game most of us would have played 17...Bxg1 rather than 17...Rd7>

I think you could be correct. I would have played 17...Bxg1. Good observation

Mar-29-12  cyclon: Whilst preparing meal I for some reason thought for the moment the diagram position in my mind as if there was something wrong and yes - my 19. -Qxh2+?? is an awful mistake. Just 20. Kxh2 and it's over. I was mixing two moves first being 20. Rxh2, which of course White doesn't have to play. On behalf of myself I have to say that I've been physically tired lately because of the work. When puzzles gets more difficult trying to solve them too hastily when tired results more easely oversights and blunders. What comes to explanations in general regarding Chess certain IM once observed that " .. I have never won a HEALTHY opponent...".
Mar-29-12  Rosbach: Nice little mate. I missed it though.
Mar-29-12  TheBish: <chrisowen>, I'm begging you... please lay off the absinthe!
Mar-29-12  TheBish: J Whitehead vs Biyiasas, 1977

Black to play (19...?) "Medium"

I found the first move right away, but had trouble finding the follow-up. Black has much better development, and White's back rank seems a little suspect, so it's natural for there to be a combination.

19...Bc4!

This was easy to find, since 20. Qxc4? loses to 20...Rd1+ and mate in a few.

20. Qe1 (forced) Bf1!

I was looking at things like 20...Bd3, trying to weaken d1, but that fails to 21. Bxd3 Rxd3 22. Nd2.

21. Qxf1

Also losing is 21. Rd2 Rxd2 or 21. Rg1 Bxg1, with mate looming on g2.

21...Nxg3+ 22. Rxg3 Qxf1+ 23. Rg1 Qxg1#.

Mar-29-12  rhickma4: I think Black can exploit the overworked Q with
19...Bc5 20.Qe1 Bf1

If 21.Qxf1 then 21...Nxg3+ wins, and the White Rook has no good moves.

Mar-29-12  goldenbear: I got the solution, and then I noticed the bishop on b6. Incredibly, the combination works without the dark bishop!
Mar-29-12  stst: check the Q instead of the K!
19...Bc4, and W Q cannot take the B for afraid of the R check. But if 20.Qe1 Bf1 will leave W in lurch, for any move will get mated and Q loss, e.g. 21.Qxf1 Nxg3+ whether R takes or not is losing. Else? -- NO Else!
Mar-30-12  dragon player: Black would like to play Rd1+, but at the moment, d1 is too well defended. Therefore, I think this is the keymove:

19...Bc4

Distracting the queen.

19.Qe1

If 19.Qxc4 Rd1+
20.Bxd1 Rxd1+
21.Rg1 Rxg1#

19...Bf1!

White is in trouble now. 20.Qxf1 Nxg3+, moves with the rook lose an exchange.

Time to check.

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

Yes, I was right. Lets soon move on to the fridaypuzzle, since I'm again too late.

4/4
