  diagonalley: ... oh this is a bog-standard BxRP+ et seq. ... how on earth is it that black, a 2220 rated player, can wander into such a well-worn losing position!?! ... there's hope for <diagonalley> yet!

  agb2002: The material is identical.

Black threatens to eliminate the light square bishop.

The position looks very close to that at move 15 in the most famous game Lasker vs J Bauer, 1889. Therefore, 15.Bxh7+:

A) 15... Kxh7 16.Qh5+ Kg8 17.Bxg7

A.1) 17... Kxg7 18.Qg4+

A.1.a) 18... Kf6 19.Qg5#.

A.1.b) 18... Kh6(7,8) 19.Rf3 wins. For example, 19... Qd8 20.Rh3+ Bh4 21.Rxh4+ Qxh4 22.Qxh4+ Kg7 23.Qg5+ Kh7 24.Rf1 Rg8 25.Qe7 Rac8 26.b4 wins yet more material.

A.2) 17... f5 18.Qg6

A.2.a) 18... Rf7 19.Bh6+ Kh7 20.Qxf7 Bd6 21.Qf6+ + - [R+2P vs B].

A.2.b) 18... Rfb(c,d,e)8 19.Bh6+ Kh8 20.Qg7#.

A.2.c) 18... Bd6 19.Bf6+ Qg7 20.Qxg7#.

A.2.d) 18... Rf6 19.Bxf6+ Kf8 20.Bg7+ Kg8 21.Bh6+ Kh8 22.Qg7#.

A.3) 17... f6 18.Qg6 as in A.2.

B) 17... Kh8 18.Qh5

B.1) 18... f6 19.Bg6+ Kg8 20.Qh7#.

B.2) 18... Rfb8 19.Bg6+ Kg8 20.Qh7+ Kf8 21.Qh8#.

  morfishine: <15.Bxh7+> and Black King cannot get away
Oct-22-15  JimmyRockHound: If black takes with the Queen on move 14 my engine can't see the win.

14...Qxc5 15.Bxh7+ Kxh7 16.Qh5+ Kg8 17.Bxg7 Qxe3+ Equal.

Oct-22-15  JimNorCal: Another K-side attack to compare. Same attacker but the attempt fails in this one. L Filatov vs P Bierkens, 2000
Oct-22-15  saturn2: Instead of sacrificing the 2nd bishop 17 Rf3 seems to work as well.
Oct-22-15  Cheapo by the Dozen: This looks like a classic double bishop sac situation. Let's consider a main line of

15 Bxh7+ Kxh7
16 Qh5+ Kg8
17 Bxg7 Kxg7
18 Rf3 (Black twiddles thumbs)
19 Rg3+ Kf6
20 Qg5#/Qh6#

On Move 15, Black's only possible deviation is 15 ... Kh8. 16 Qh5 then mates quickly.

Black's Move 16 is totally forced.

On Move 17, Black's only chance to deviate is to make luft via 17 ... f6/f5. But 18 Qg6 then forces a quick mate.

On Move 19 all I left out was the useless 19 ... Bg5.

So if Black has a chance, it's to use the tempo on Move 18. But:

Moving the rook for luft allows a quick Qh8#.
Playing ... Ne4 just delays things by a move.
Other choices avert one but not both of Qg5# and Qh6#.

Black's most complex try to throw in a monkey wrench is 18 ... Bh4, but that leaves us with

15 Bxh7+ Kxh7
16 Qh5+ Kg8
17 Bxg7 Kxg7
18 Rf3 Bh4
19 Qg4+ Kh8/Kh7/Kh6/Kf6
20 Qxh4+

and mate soon follows.

Oct-22-15  Cheapo by the Dozen: Ahh. The game line is a little more forcing.

Anyhow, I like this opening. It seems to combine two things I used to play -- Colle System and Larsen's.

  Willber G: <Cheapo by the Dozen: This looks like a classic double bishop sac situation. Let's consider a main line of

15 Bxh7+ Kxh7
16 Qh5+ Kg8
17 Bxg7 Kxg7
18 Rf3 (Black twiddles thumbs)
19 Rg3+ Kf6
20 Qg5#/Qh6#>

I thought 18. Rf3 was good at first, but couldn't find a win if black plays 18... Rh8

A) 19. Qg4+ Kf8

B) 19. Rg3+ Bg5
B.1) 20. Qxg5 Kf8
B.2) 20. Rxg5 Kf6

I think <An Englishman> is correct, 18. Qg4+ is critical to keep the BR off h8 allowing an attack on the WQ and an escape for the BK via f8.

  CHESSTTCAMPS: Material and the number of developed pieces are even, but white has a big advantage in the quality of the bishops and king safety. At first glance, this looks like a classical Bh7+ sacrifice. At second glance, this looks like a classical two-bishop sacrifice.

15.Bh7+! Kxh7 (15... Kh8 16.Qh5 Rfd8 17.Bg6+ Kg8 18.Qh7+ Kf8 19.Qh8#) 16.Qh5+ Kg8

Now after the rook lift 17.Rf3 (the obvious continuation) f6, black builds an escape hatch for his king. White can preempt this defense with 17.Bxg7!! and now:

A. 17... Kxg7 18.Qg4+ Kh8 (Kf6 19.Qg5#!) 19.Rf3 f5 20.Rh3+ Bh4 21.Rxh4+ Qh7 22.Rxh7+ Kxh7 23.Qh5+ is winning.

B. 17... f6 18.Qg6 (many novice players would choose Qh8+) Rf7 (otherwise 19.Bf6+ or Bh6+ forces mate) 19.Bh6+ Kh8 20.Qxf7 is winning

C. 17... f5 18.Qg6 Rf7 19.Be5+ wins queen.

D. 17... other 18.Qh8#

Time for review....

  CHESSTTCAMPS: Steve is a long-time stalwart of the mid-Atlantic chess scene, as was his late father Jack. I recall that Steve appeared to have a winning position against GM Dimitri Gurevich in a key tournament game, but Gurevich escaped with a draw.

Premium Chessgames Member
  CHESSTTCAMPS: Steve also writes well, as in this memorial to a chess friend: http://www.uschess.org/content/view... The winner of this game, as the chess biography indicates, also met a premature demise.

  whiteshark: one from the Game Collection: 70e_Double Bishop Sacrifices

I gave a lecture on it lately. ;)

Oct-22-15  BOSTER: The question is only one.
Why Mayer with rating about
2000 didn't know double bishop sac.?
Oct-22-15  belgradegambit: Easy Thursday . The double bishop sac is obvious and the queen check to nail black into the corner before R-f3 also comes up quite often.

  kevin86: Either black can walk into a mate in one or he can soon face a queen and a rook without defenses.

  thegoodanarchist: I am guessing that White either studied Vukovic's The Art of Attack in Chess, or else Lasker's famous double bishop sac game.
Oct-22-15  Chess Dad: I saw everything up to 18. Qg4, but didn't see from the beginning that the response of Kf6 allows a Dovetail mate with 19. Qg5#. Had I seen that, I think I would have also been able to see that 18... Khx would be met by the rook lift 19. Rf3 with no real defense possible. (There's a brief delay possible with 19... Qxf4, but 20. exf4 takes care of that.) In short, I saw the likely puzzle moves but would have been hesitant to throw away two bishops OTB without seeing that it really did lead to mate.

I remember somebody essentially saying about a year ago that a person is better off memorizing mating patterns than memorizing and naming opening sequences.

It definitely would have helped me on this puzzle.

---
[edit] Oh, so there is a better defense and not just a delay for the rook lift. I see 19... Qd8 from stst above does delay quite a bit more than 19... Qxf4.

Oct-22-15  benjaminpugh: I spent too much time trying to decide which bishop it was better to sacrifice, never considering the answer was "both."

  TheFocus: Pretty easy for a Thursday.

Tactics study does pay off.

Oct-22-15  grasser: I learned this combination from the Lasker-Bauer game. I played it once myself. G Grasser vs M Camejo, 2009

  TheFocus: That was a nice game <Grasser>.
Oct-23-15  grasser: <TheFocus> Thank you. I was taught by Dr. Joseph Platz from 1978-1980. Dr. Platz was a friend and student of Lasker. Here is the famous game:

Lasker vs J Bauer, 1889

  TheFocus: So the student of the student play's the master's masterpiece!
Oct-31-15  grasser: If only people were not so frightened of me there would be many more examples. I love to teach, but was put on trial and found guilty of "Solicitation without a Permit." The fine came to $500. So these little kids can go to hell for all I care. I hate losing to them anyway.
