  playground player: So who said mating with Bishop and Knight was hard?
May-23-11  estrick: <Patriot: 8.h3 makes sense but I'm not sure about 12.a3. This seems to waste time. 13.Nh4 seems to be the big loser,> <estrick: Can't believe how White, a 2400, could play so poorly.> <scormus:neither can I, completely outplayed. e.g. as if he thought "I can win easy here with 15 Bxa6" Ooops!>

Yeah, I thought 8. h3 was unnecessary. 13. a3 seems to be the same kind of move. 14. Nh4 to chase the bishop away leaves the knight on the rim not doing anything, although I guess it clears the f3 square for the queen. 15. Bxh6 looks worse than one of my failed kingside attacks, and it allows Black's knight to take the pawn on d4, putting it in a very powerful place. 16. Qxb7 is, at first blush, a most inexcusable pawn grab, but after a second look, I see that the Dame was nearly trapped and the only other available square was a retreat back to d1. This underscores the weakness of White's previous three moves and the incoherence of whatever "plan" he may have had.

Black then drives White's queen to a square where it will be totally useless in defending the king, while impudently planting another piece in the center of the board. Next, Black forks White's rooks, which might have been prevented if White had retreated queen to d1 instead of grabbing a pawn on the far side of the board. So, on move 19 White captures the offending bishop on e4, which he could have done the previous move, which would have kept his queen on the long diagonal. On move 20 White skewers the Black queen and rook with Bb5. So what? It merely 'forces' Black to triple up his heavy artillery on the e file, much like White's 16th move when he 'forced' Black to double up his rooks on the e file. And the bishop move did nothing to save his grim knight which was hanging as well.

After Black takes the rook on a1 White should resign then and there. He can't maintain the material balance by taking Black's rook on e8, which he so cleverly skewered one move earlier, because that would cause the loss of his queen to a discover attack after Black plays Bh2+, thanks to White's having 'forced' Black's queen to a better square. Capturing the knight on a1 in order to only be down the exchange instead of a whole rook draws a crucial defending piece away from where it needs to be, which allows Black to carry out the flashy sacrifice of his entire of column of heavy pieces that he had lined up on the e file.

It's reminiscent of Morphy's Opera House Massacre, or Anderssen's Immortal Game or Evergreen Party. White's play was terrible.

May-23-11  Wyatt Gwyon: Pretty complicated little game. Nice Monday puzzle.
May-23-11  Patriot: <estrick> 8.h3 has several purposes, both dealing with protecting the isolated pawn on d4. It keeps the knight from being pinned by ...Bg4 and mostly it allows Be3 without being harassed by ...Ng4. 12.a3 looks like a beginner move containing an irrational fear of a bishop pin.

There is a general principle that says whenever you have an isolated pawn, you should try to retain your minor pieces for a kingside attack. White actually did this by snapping off a kingside pawn. Obviously it didn't work but it's not so terrible of play in my opinion. Here's one way of looking at it--it was a clever way to lose. But hey that's chess sometimes!

May-23-11  sevenseaman: Here is another (a played game) example of this type of smothered mate that does not use the second rank pawns for the smothering and the K is in an artificial corner with only one recapturing piece on call.

Schaaf-Hartlaub, Bremen 1907

B in 4.

*I think most or all smothered mates reach execution in 4 moves?

May-23-11  estrick: Hadn't heard that g.p. about retaining minor pieces when you have an isolated pawn, but it makes sense. But White's "kingside attack" seemed pretty lame, and uncoordinated; and allowed Black to centralize his pieces on dominating squares, while scattering White's piecs to various corners.

Instead of 13. Nh4, which is where I think White really started going off the tracks, how about Qd2, which puts a little more bite into the attack on h6, maintains protection of the d pawn with both the knight and the queen, connects the rooks, and avoids having the queen chased around, which is what happened after it was misplaced on f3?

May-23-11  beenthere240: 15. Bxh6 says it all.

Yet another stretch to the boa constrictor's smothering muscles!

May-23-11  M.Hassan: <patzer>,<OhioChessFan>: I have continued the line mentioned by you and looks like things would have been in White's favour!:

May-23-11  Fischer of Men: The final position reminds me of:

A Steinkuehler vs Blackburne, 1863

May-23-11  Patriot: <sevenseaman> I would start with 1.Bd5+:

A) 1...Nc6 2.Bxc6+ Rxc6 3.Qxc6#

B) 1...Nb7 2.Qb8+ Rxb8 3.Rxa7+ Bxa7 4.Nc7#

C) 1...Rc6 2.Bxc6+ Nb7 (2...Nxc6 3.Qxc6#) 3.Qb8+ Rxb8 4.Rxa7+ Bxa7 5.Nc7#

It's important to not get the move order wrong in B, for example: 1...Nb7 2.Rxa7+?? Bxa7 3.Qb8+ Bxb8

May-23-11  stst: The corner has to be preserved! & a Q sac will get it: 27.....Qg1+
28.RxQ Nf2#
as h2 is in the B's fire line, and g1 is blocked by Bk'w own R.
May-23-11  Patriot: In line C I missed a quicker line, making it at most a mate in 4 problem: 1...Rc6 2.Qxc6+ Nxc6 (2...Nb7 3.Qxb7#) 3.Bxc6#
May-23-11  TheFocus: Loved it. 8 seconds to solve. I should have been faster though.

  ajk68: I am trying to figure out whites 18th move. Is there a reason not to exchange the bishop for a knight, or Qxa7 ?
May-23-11  Patriot: <<ajk68>: I am trying to figure out whites 18th move. Is there a reason not to exchange the bishop for a knight, or Qxa7 ?> Houdini says Qxa7, Qa6, and Nxe4 are practically even--as in a drawish game. But I would prefer Qxa7 as a human player.

Also according to Houdini, white played very well for a long time. Nh4 wasn't so bad after all and it proves white didn't play such a lousy game--at least for a while!

May-23-11  alachabre: A very quick glance, and my chess head said, "I smell a smothered mate." Didn't even have to pause to think it's queen sac Monday:

27. ... Qg1+
28. Nxg1 Nf2#

May-23-11  alachabre: <ajk68: I am trying to figure out whites 18th move. Is there a reason not to exchange the bishop for a knight, or Qxa7 ?>

My thought is that possibly White feared the tactical complications and wanted to give support to the white square bishop.

May-23-11  sevenseaman: <Patriot> <B) 1...Nb7 2.Qb8+ Rxb8 3.Rxa7+ Bxa7 4.Nc7# > nails it.

A) and C)?

May-23-11  sevenseaman: <Fisher of Men> A Steinkuehler vs Blackburne, 1863 is spot on.

  Phony Benoni: <estrick> <Patriot> I think there is a little sense to <12.a3>:

click for larger view

White's ♗c4 is well placed, attacking d5 and f7. 12.a3 gives it a place to retreat along the diagonal should Black play ...Na5 at some point. It's a very common idea.

Perhaps White can get away with this; after all, is Black really primed for an attack in the diagrammed position? I don't know if White played so badly; to my mind, he made an error in judgment in switching too quickly from Slow Positional Crush to Quick Tactical Strike. Black played energetically and well in counterattack when given the chance.

May-23-11  Patriot: <Phony Benoni> You may be right about 12.a3. In fact, keeping the bishop on that diagonal makes a lot of sense because it helps control the square in front of the isolated pawn which may make it possible to advance it in some lines if need be. White also reserves the possibility of playing Ba2-b1 and Qc2 with threats against the black king at some point.

But I do think white was justified with most of his play.

Yes, there's a Bishop on d6.
