Blackburne vs Lasker, 1892


click for larger view

Dec-22-20  Mayankk: 34 ... Rf1+ 35 Rg1 Bf3# is the quickest route to victory.

But let’s say in a Blitz game we fail to spot 34 ... Rf1+ and play 34 ... Bf3 instead. Is it still a Black win ?

Dec-22-20  malt: 33...Q:g2+ 34.R:g2 Rf1+ 35.Rg1 Bf3#
Dec-22-20  Brenin: This seemed even easier than it did on a Monday, three months ago. Is the supply of interesting positions so rare that we have to recycle them as rapidly as this?
Dec-22-20  Cheapo by the Dozen: Obvious idea: Attack the g2 knight.

Tries without involving the f8 rook don't work. OK; how can we involve that rook?

Once I got that far, solving the problem became immediate.

Dec-22-20  Brenin: <agb2002>: In your <Blackburne vs Lasker, 1892> puzzle, 35 ... f4 wins a piece for a pawn, but is this relevant to today's POTD, apart from being equally easy?

It does. Black threatens Bxg2+ with Rf1#, there aren't many moves that protect against this. 35.h4 Bxg2+ 36.Kh2 and now either Bf3+ or Rf1 are horrible. SF gives 35.Bf2 Rxf2 36.Qg1 Bxg2+ 37.Qxg2 Rxg2 38.Kxg2 g4 -+ after which White's helpless against the B+P, considering the King's also cut off.

Dec-22-20  saturn2: <agb2002> It is never clear to me in your puzzles who is to move.

  offramp: Lucky Miciano.
Dec-22-20  Damenlaeuferbauer: Same procedure as nearly 3 months (September 28, 2020) ago! Does <Chessgames> really think, that chess players have such a bad memory? After almost 90 days of pondering, the then 18 years young Philippine international master John Marvin Miciano finally found the mate in 3 moves with the nice queen sacrifice 33.-,Qxg2+! 34.Rxg2,Rf1+ 35.Rg1,Bf3#. I hope, that we will hear more of him in 2021! I wish every true chess player out there merry Christmas and a happy new year from Germany!
Dec-22-20  goodevans: <saturn2> The ellipsis ( ... ) in <agb2002>'s "35...?" indicates that it's black to move (the ellipsis represents white's absent move). If it had been white to move then it would have been a single full stop or period.

  gawain: An early week puzzle so one looks for something dramatic. The combination practically plays itself. Sweet.
Dec-22-20  Hercdon: Easier than Monday imo
Dec-22-20  BxChess: Thanks <agb2002>. I enjoyed the puzzle although I found it more difficult than your 1.5 rating suggests.
Dec-22-20  Everett: <An Englishman: Good Evening: Used the Botvinnik Formation with both the Black and the White pieces, but cannot deny that when it goes bad, it goes bad like two tons of fish in a one ton dumpster during a heat wave.>

Greetings again, fellow fan of the Bot.

Black plays one of the most effective responses here, and White needs to be mindful of some crucial moments.

In such structures, 7.. Be6?! (mistake imho) is best met by <8.Nd5!> and <9.f4> White misses this and allows Black to equalize after 8.Be3 Nd4!

In my experience it is best to leave the Bc1 dormant until I have more information. It might go to d2, e3, g5 (after Nd5 especially) or wait until the nature of the f4-pawn push is decided.

Always good to remember that White should not be concerned with his opponents f-pawn push. On move 21 White should play exf4 and Bg2, regaining control of d5.

Interesting game with some good lessons in what and when to swap minor pieces.

Dec-22-20  zb2cr: The laws and rules of chess have not changed, so the solution I found on 28 Sep 2020 still works!

Actually, it looks like Black's only move not to end up with the worse position.

The rating is very subjective and only orientative of the time one is going to 'invest' in the case of attempting a complete solution.

Nothing to do with today's POTD. It's just a constructive way of complaining.

Dec-23-20  saturn2: <goodevans, agb2002> thx
