Oct-11-15  markbstephenson: After 22.b4? black's forces gracefully stampede into white's king position

  Gregor Samsa Mendel: I was thinking of 27..Bf3, but that is parried by 28 Bf1. So the logical thing to do is prevent the white bishop from getting to f1.
Feb-16-17  patzer2: My attempt at today's Thursday puzzle (27...?) is a second best attempt with 27...Bf3 which according to the computer wins after 27...Bf3 28. Qb1

If 28. Bf1, then 28...Be4 29. Qd1 Nf3+ 30. Kh1 (30. Kg2 Nxd2+ ) 30... Bxg3 31. fxg3 Nxd2+ 32. Bg2 Bxg2+ 33. Kxg2 Nxb3 (-6.77 @ 19 depth, Deep Fritz 15)

28... Qh3 29. Bf1 Bg2 30. f4 Re1 31. Qxe1 Nf3+ 32. Kf2 Nxe1 33. Bxg2 Qxg2+ 34. Kxe1 Qg1+ 35. Ke2 Qxh2+ { (-3.26 @ 26 depth).

However, the game move 27...Be2 (-10.25 @ 28 depth, Stockfish 260616) is strongest.

After the game continuation 27...Be2 28. Bxe2 (28. Bf5 Nxf5 ) 28...Qh3 Black resigns in lieu of the mate-in-two threat 29. gxh4 Qxh2+ 30. Kf1 Qh1#.

P.S.: For a White improvement, instead of 22. b4 allowing 22...Bg4 (-0.66 @ 24 depth, Stockfish 7), better is 22. Nh4 Bh3 23. Ng2 = (-0.10 @ 27 depth, Stockfish 110217)

Feb-16-17  ChessHigherCat: I got 27...Be2 because it's the only move that prevents Bf1, but I was expecting 28. Bxe2 Rxe2 with the threat of 29...Qh3 30. fxh5 Bxh2+ 31. Kh1 Bg3+ 32. Kg1 Qh2+ 33. Kf1 Qf2#. I think I missed 27...Be2 28. BxB RxB 29 Kf1! though, which foils my plan, so the game line was much better.
Feb-16-17  latebishop: My winning move was 27...Bd1,which seems as good as 27...Be2?

  al wazir: 27...Bd1 28. Rxd1/Qxd1 (28. Bb5 Qh3 29. Bf1 Nf3+ 30. Kh1 Qxh2#) Qh3 29. gxh4 Bh2+ 30. Kh1 Bg3+ 31. Kg1 Qh2+ 32. Kf1 Qh1#) .

But 28. Bf5 spoils the fun.

Feb-16-17  latebishop: Thanks Al Wazir. Didn't see that resource!

  agb2002: Black is one pawn down.

White threatens gxh4, axb6 and a6.

The first idea that comes to mind is 27... Bf3, trying 28... Qh3 but White has 28.Bf1. This suggests 27... Be2:

A) 28.Bxe2 Qh3

A.1) 29.gxh4 Qxh2+ 30.Kf1 Qh1#.

A.2) 29.Bf1 Nf3+ 30.Kh1 Qxh2#.

B) 28.gxh4 Qg4+ 29.Kh1 Bf3#.

C) 28.f3 Qh3 29.Kf2 (29.gxh4 Qxh2#) 29... Qg2+ 30.Ke1 Qf1# (or Nxf3#).

D) 28.f4 Qh3 29.gxh4 (29.Kf2 as in C) 29... Qg4+ 30.Kf2 (30.Kh1 Bf3#) 30... Qf3+ 31.Kg1 Bxd3 32.Qd1 Re2 33.Qf1 Qg4+ 34.Kh1 Be4+ and mmate next.

Feb-16-17  saturn2: I took <27 ...Bd1> I did not see <28 Bf5 by al wazir> but i am not convinced it really is the spoiler. 28..QxBf5
and either after 29 QxQ NxQ or 29 QxBd1 Qe4 30 gxNh4 Qxh4 black is attacking.
Feb-16-17  AlicesKnight: I looked at ...Bd1 first to allow the tempo gain for the Q to enter. But after 28.Qxd1 Qh3, 29.Bf1 leaves both the key squares g2 and f3 protected. 27... Be2 is less flashy but deadly, leaving the White B overloaded.
Feb-16-17  SantGG: Could White defend if did'nt play 27.Nb3? Was it a blunder? tks.
Feb-16-17  saturn2: Now I ses 27 Bd1 even looses, AlicesKnight
Feb-16-17  Carlos0012358: Clearing the black Q diagonal to h3 seems the best tactic. Therefore the black B (g4) needs to get out of the way.

One must also work to prevent white to move Bf3 because it would trump .....Qh3. So:

27.....Be2 28.BxB Qh3 and white mates in three moves.

White can also respond with 28.gxh4 or 28.f3 or 28.f4 to clear space for the white K but white has a path to mate in a few moves.

Feb-16-17  aaronlwilliams: Just generally speaking from a rook-ie standpoint, it seemed to me white did a lot of pointless jockeying around while black finally got to the point.

Wasted moves, wasted moves, lost tempo, you more often than not end up in trouble.

Black has all sorts of firepower aimed at white's king: 2B+N+Q+R!

So, right away, we can expect a sacrifice of some sort to bust things open. As with other puzzles this week, it features a piece that seems to be "in the way" of our best attacker, the queen. In this case the Bg4 is blocking our Q from hitting h3.

<~~~ START PRETENDING ~~~>

Let's pretend that our Bg4 vanished:

On one hand, if it's black's move, we would play 27...Qh3


click for larger view

We threaten ...Qg2#, and white is helpless
- If 28.gxh4, then 28...Qxh2+ 29.Kf1 Qh1#
- If 28.Bf1, then 28...Nf3+ 29.Kh8 Qxh2#

On the other hand, if it were white's move in the first position above, he would surely defend against this attack with either:
- 28.Bf1 (stopping ...Qh3), or
- 28.Qd1 (stopping ...Nf3).

<~~~ END PRETENDING ~~~>

Since that Bg4 is there and we can't make it vanish, we should find a place to put it where it blocks white's defensive moves enough to keep our threats alive.

Based on the pretend analysis above, this calls for <27...Be2!>

This stops both of white defensive moves! 28.Bf1 is blocked and 28.Qd1 loses the Q.

White has no good way to stop the attack. He may try <28.f4> to block our DSB and give the king an escape at f2, but then <28...Qh3 29.gxh4 Bxd3>

If white saves the queen (e.g. 30.Qd1) black has 30...Re2 and it's over.

Feb-16-17  YouRang: <SantGG: Could White defend if did'nt play 27.Nb3? Was it a blunder? tks.>

White was already losing by his 27th move, but <27.Nb3> did speed up the process a bit.

Feb-16-17  Afroim: To <agb2002> and <patzer2>: I think on 27... ♗f3 28.♗f1 is not a good defense, because 28... ♗e4 and 29... ♘f3+ deteriorates white's position.
Feb-16-17  morfishine: I couldn't put my finger on this one though I was circling around the theme(s), sometimes thats just the way it goes

Feb-16-17  Mendrys: After a short think Houdini came up with the following humorous variation as best after 27...Be2!

28. Bf5 Nxf5 29. Bg5 fxg5 30. Re1 Bf3

Feb-16-17  ChessHigherCat: Houdini's amazing vanishing act. Watch me make a bishop disappear on f5! And now another one down the hatch on g5!
Feb-18-17  Moszkowski012273: 10.g3?
