Jan-28-09  TheaN: Wednesday 28 January


Material: /+\ ♗+♗/♗+♘

Candidates: Bxf7, Rd8, <[Bxf7>

Somehow this puzzle seems easier than yesterday's, mainly due to the limited amount of moves available to White. After I couldn't make 33.Bxf7 Qxf7 work for White, I went to 33.Rd8, where 33....Qxd8?? 34.Bxf7 Ke7 35.Qe6 is mate, but 33....Kxd8 and White can't make anything from the position.

Combining the idea of the deflection, in the main line the deflection of the King from his Queen, compared to the variation above where the Queen is deflected from the King, and the mate threats decide the game.

<33.Bxf7!> it does work. Black's reply is pretty much forced.

<33....Ke7 34.Qe6 1-0> as comparable to the variation with 33.Rd8 Qxd8? listed above.

<33....Qxf7 34.Rd8!> and now this move works as it would deflect the King from the Queen, where in the initial position the King is not defending anything. It may be advisable to White to take the Rook, but a pretty hopeless game ensues. If he doesn't, it's worse though:

<34....Ke7 35.Nc8!> White enforces that the Black King takes the Rook with this move.

<35....Kxd8 36.Qxf7 > and this position is very hopeless, with the Rook en prise: Black has to take to save the Rook...

<36....Kxc8? 37.Qxf8 > ...but loses two pieces, and thus one netto, in return. Kxd8 is forced.

<34....Kxd8 35.Qxf7 > the Queen and Knight are so well placed compared to the Rook and Bishop of Black: with a combination of Bg5 and the threats the Queen is already enforcing, Black cannot find reasonable defenses. For example, 35....Nbd7 36.Bg5! Be7 (Nxb6? 37.Bxf6 ) 37.Nxd7 and Black loses another piece. After 35....Nfd7, Black is completely paralyzed, and with any other move Black loses a piece outright. Hopeless.

Time to check.

Jan-28-09  Aas: <al wazir>: Rd7 doesn't work in MAJ's puzzle. After Nbxd7 Qxf7+ Kd8 black has a cramped position, but he is still a rook up. The pieces in the black camp are protected, and there just isn't any more white pieces to bring to the attack.

Correct is Nd7, the difference being that after Nxd7 Qxf7+ Kd8 the knight at d7 is pinned, black bishop at f8 is up for grabs, and black's position cripples (verifyed by fritz).

Jan-28-09  TheaN: 2/2.

Fair enough.

Jan-28-09  Woody Wood Pusher: These micro-second solves really should not be around by Wed IMO.
Jan-28-09  dukesterdog2: After analyzing 33. Rd7 for a minute, I switched to 33. Bxf7+ and found the correct line fairly quickly after that.

  patzer2: For today's Wednesday "medium difficulty" (two star) puzzle, White plays the decoy sham sacrifice 33. Bxf7+!! to set up the Queen for a deflection (removing the guard or defender) combination after 33...Qxf7 34. Rd8+! Ke7 35. Nc8+ .

  johnlspouge: Wednesday (Medium/Easy)

A Naumann vs W Teerapabpaisit, 2008 (33?)

White to play and win.

Material: B for N. The Black Ke8 has 1 legal move. The White battery Qb3 and Bc4 are attacking Pf7, which therefore requires protection from both Ke8 and Qc7. The White Rd1 has an open file, on which it can check with Rd1-d8+ or block with Rd1-d7. The White Nb6 supports Rd1-d7. Only the White Be3 requires activation. The White Kg2 is open on the 2-nd rank but secure from checks.

Candidates (33.): Bxf7+, Rd8+, Rd7

33.Bxf7+ Qxf7 [Ke7 34.Qe6#]

Now, White decoys Ke8 from the protection of Qf7.

34.Rd8+ Ke7 [Kxd8 Qxf7]

In the alternative variation, White has Q+P for R+B. Calculation can therefore stop, but Be3-g5 is likely to win more material.

35.Nc8+ Kxd8 36.Qxf7 (threatening 37.Nxa7, 37.Qxf8+ or 37.Qxf6+)

Presently, White has Q+P for R+B, so only calculation to quiescence is required. Black can play:

(1) 36Ra7-moves 37.Qxf8+ wins an extra B

(2) 36Kxc8 37.Qxf8+ Ne8 [else, 38.Qxf6] 38.Qxe8+ wins an extra B

(3) 36else 37.Nxa7 wins an extra R

White has an overwhelming material advantage.

<Examine checks, captures, and threats first!>

Jan-28-09  FizzyY: umm bxf7.
<Mostly Average Joe> Rd7

Hi, <whitebeach>.

Possibly, you have just been meeting the wrong Girl Scouts ;>)

Jan-28-09  YouRang: What I see is a hot point at f7 (B+Q battery) which I can use to deflect black's overworked queen (which is busy guarding d8 and c8 as well as f7): 33.Bxf7+ Qxf7.

Now black's problem is that his queen is guarded only by its king, and some key squares near the king are now unguarded. So, lets distract the king using the newly unguarded d8 square: 34.Rd8+!

This forces 34...Ke7 (not 34...Kxd8 35.Qxf7 ), and then we hit the newly unguarded c8 square: 35.Nc8+, forcing 35...Kxd8 and the loss of the queen, 36.Qxf7

Damn it, sir, but you make it sound so sexy! Excellent analysis as always.

May I return your high praise by saying that your new "unplugged" analyses are very helpful, <Once>?

<Damn it, sir, but you make it sound so sexy!>

Not as sexy as 0.777777... :)

Jan-28-09  just a kid: Ok.I spent about 2 minutes on this puzzle and I looked at 34.Rd8+?(I know it's pretty stupid,but you never know.)Then I saw the Queen and bishop on a battery toward f7 and found 34.Bxf7+!The point is 34...Qxf7 loses to 35.Rd8+! Kxd8 36.Qxf7.I'm pretty confident about this one so I will check now.
Jan-28-09  just a kid: Okay I didn't see Ke7,but I was pretty sure White would win anyway so I'll count this as 3/3
Jan-28-09  Kasputin: Material is even but with so much going on around the black king I just started with one variation: 33. Rd8+ Qxd8 34. Bxf7+ Ke7 35. Qe6#. Of course black doesn't have to play ...Qxd8 but instead can take with the king. But looking at this one line (noticing for instance that d7 is denied to the black king because of the white knight as well as the white rook) really helped me to grasp the position and the advantages of the next candidate move became immediately obvious:

33. Bxf7 Qxf7 (essentially forced since ...Ke7 lead to mate with 34. Qe6#)

34. Rd8+

Now comes the rook move since 34 ...Kxd8 leads to 35. Qxf7 and white comes out with a queen and a pawn for a rook and a bishop. But that would not be the end of troubles for black because of how uncoordinated black's pieces are. White has chances to capture one of the black pieces and if black defends with moves like ...Be7 or ...Nbd7 or ...Nfd7 then white has the strong looking Bg5. In any case there looks like a lot that white can do and no doubt white would have a large advantage. So instead of 34 ...Kxd8 black can try:

34 ...Ke7
35. Nc8+ Kxd8
36. Qxf7 Kxc8 (this is necessary because the rook on a7 is attacked by the knight and moving the rook makes no sense because 37. Qxf8+ captures the bishop and protects the c8 knight).

37. Qxf8+ (white plays it anyway) and at this point there is no way to defend the f6 knight.

White comes out with a winning position after 33. Bxf7+ no matter what black does. Time to check it out.

Jan-28-09  Kasputin: I notice some interesting themes emerging so far this week. Each of the 3 puzzles has involved a knight fork in some way, although the knight forks haven't necessarily been obvious. Also today's and yesterday's puzzles involve a surprise rook check landing next to a king - a poisoned rook it turns out with a knight (surprise surprise) playing a role in the combination.

Lets see if the CG folks continue to weave these thematic webs.

Jan-28-09  PinnedPiece: Go the bishop and rook moves but then wasn't sure of black's best for 34. Saw enought to convince me to play it out in the game, and found the knight move then.

Initial analysis time: 1 min 45 sec. Wed par: 3 min.

Result: Good!

Jan-28-09  ruzon: I am happy for myself that I found all the variations and the correct series of moves played in the game. Usually I rely more on my intuition, which is often wrong.

I give kudos to Naumann for seeing the weak f7 way back with 28.♕d3!, allowing him to set up the Queen and Bishop battery while protecting the e4 pawn.

Jan-28-09  Utopian2020: A good puzzle for Wednesday.
Jan-28-09  SmotheredKing: Took me a couple of minutes, kept looking at 33. Rd8+ and mate threats at e6, but I couldnt find an answer for 33. ...Kxd8. Then I looked at 33. Bxf7+ Qxf7 (otherwise Ke7 Qe6#)34 Rd8+, when 34. ...Kxd8 allows 35. Qxf7, and 34. ...Ke7 35. Nc8+, and black must allow Qxf7 on the next move; in addition, both the Nf6 and Bf8 are hanging and the Ra7 is attacked by the knight, so that the best black can do is take the Nc8 and be down queen and pawn for rook, . Of course, if I were actually playing this game I doubt Id have the guts/insight to play Bxf7+.
Jan-28-09  WhiteRook48: nice bishop sac and seeing as how that Rook was on the d-file, could have been solved by me had I not LOOKED AT THAT SOLUTION! (I should really stop doing this to puzzles)
Jan-28-09  blacksburg: fun puzzle, cool little deflection tactic. gotta watch that f7 square, even if its 30 moves into a KID :)
Jan-28-09  zenpharaohs: Aas: "Rd7 doesn't work in MAJ's puzzle.

Correct is Nd7, the difference being that after Nxd7 Qxf7+ Kd8 the knight at d7 is pinned, black bishop at f8 is up for grabs, and black's position cripples (verifyed by fritz)."

I thought this too, and I was going to check it with Rybka, but you saved me the trouble.

Jan-28-09  MostlyAverageJoe: < zenpharaohs: Aas: "Rd7 doesn't work in MAJ's puzzle> OOPS, indeed, I misread <al wazir>'s post. Nd7 is it (and is the move I wanted to be the solution ).
