Oct-22-11  CHESSTTCAMPS: Black is up an exchange. However, the black rook is trapped and White is in position to win back the exchange with 37.Kf1, forcing either 37... Rxf2+ or 37... Ra2. Other positional considerations (advanced white pawns and the bad bishop for black) indicate a white advantage, so perhaps white has better? When I first saw the position, my first inclination was 37.e6, but I didn't see the point for a while.


The threat of e7 is serious, throwing a burden on the BQ and gaining a tempo for winning the rook outright.

A) 37... fe 38.Qd3! (the main point - a deadly double attack) Qa1+ 39.Kh2 Qxf6 40.Qxe2 leaves white with a bishop for two pawns and a likely win given white's control of the dark squares and the low-mobility black bishop.

A.1) 38... Rxf2?? 39.Qxg6+ Ke8 40.Qg7+ Ke8 41.Qe7#

A.2) 38... Kf7 39.Qxd2 Qa1+ 40.Ka2 Qxf6 is similar to the main line.

B) 37... d4? 38.e7! Qb8 39.Qxd4 Qe8 40.Qd8 wins.

B.1) 38... dxc3 39.e8=Q+ Kh7 40.Qxf7#

C) 37... Rxf2? 38.e7! Rxg2+ 39.Kxg2 Qg8 39.Qd4 and black can't stop the maneuver Qf4-d6-d8, forcing promotion of the e-pawn.

D) 37... Qb8? 38.e7 followed by 39.Kf1 Rxf2+ 40.Kxf2 with a winning position similar to line C.

E) 37... Kf8? 38.Qe5! Rxf2 39.Qd6+! Kg8 40.ef+ Kh7 41.Kxf2 wins

E.1) 38... fe 39.Qd6+ Kg8 40.Qd8+ Kh7 41.Qe7+ Kh6 42.Qg7#

The A line seems to be black's best chance. Time for review...

  OhioChessFan: <ssm: 37. e7 Bc8 38. Qxc6 Bxe6 39. Qe8+ Kh7 40. Qf8 Qa1+ 41. Kh2 Qe5+

The least is, how are you going to deny Black a perpetual? >

Haven't looked at it in 3 hours, at work, but I think 41. Bd1

Oct-22-11  Marmot PFL: Seems that 36 e6 improves the position, 36...fe 37 Qd3 wins. So white can play e7, although even then its not a simple win. Still I found it easier than yesterday.
Oct-22-11  kevin86: The solution is to advance the pawn,the trap the rook,and finally to win the ending,despite bishop of opposite colors.
Oct-22-11  BOSTER: 37.e6-opening the lines, forced black to play Bc8.(if fxe6 Qd3) 38.e7 Bd7 and now white has more free space and black has to think about advanced e7 pawn.

No doubt that the pieces create the tension on the chessboard,like people around the world.

Usually the pieces send us a signal where something <hot> is going on. So keep your antenna up.

Somebody said:"People see what are <prepared> to see,nothing else>. What does it mean <prepared>? Think about it. Maybe this can explain our failure in double-pin puzzle.

  Sastre: 46.Kf3 would have led to an easier win. For example, 46.Kf3 fxe3 47.Kxe3 Kg6 48.Kf4 Be8 49.Ke5 and Black can't stop White's king from reaching d8 and winning the bishop.

  Jimfromprovidence: The line 37 e6 Bc8 38. Qxc6 Bxe6 39. Qe8+ Kh7 40. Qf8 Qa1+ line loses to 41 Bd1 as <OCF> points out.

If 41...Re1+, then 42 Bxe1 Qxf6 43 Qc5, below. (seeing 44 Qd4 to protect against threats from 43…Qa1).

if 41…Qxf6, then 42 Bxe2 Qa1+ 43 Kh2 (not Bf2?). If 43...Qe5+, then 44 Bg3, below. (not g3??).

Oct-22-11  Nilsson: After 37...c5! black probably can hold a draw.
Oct-22-11  abuzic: <37.e6 Bc8>
38.Qxc6 threatening Qxc8 and Qe8+ with mating possibilities looks stronger than <37...e7>:

38...Qa1+ 39.Bd1 Kh7
<39...Bxe6 40.Qe8+ Kh7 41.Qf8 Rxe1+ <(41...Qxf6 42.Bxe2)> 42.Bxe1 Qxf6>

40.Qe8 Bxe6 41.Qf8 Re1+ 42.Kh2 Qxf6 43.Bxe1 white is up B for P.

if 38...Bxe6 39.Qe8+ Kh7 40.Qf8 Qa1+ 41.Bd1
<41.Kh2? Qxf6! and black is superior>

41...Qxf6 42.Bxe2.

if 38...Kh7 also leads to same outcome.

  numbersguy70: Probably worthy of a Sunday "Insane" two moves earlier after black counters the white bishop's pressure on his rook with a Q-K fork threat. Bd1, Rc2, or Kf1 only lead to equality, while giving up the rook for knight exchange provides the initiative necessary for white to win. Very instructive example of the value of initiative.
Oct-22-11  CHESSTTCAMPS: In the game, black did not play the best defense. I was on track with the right defense, but A.2 seems to be best. Try beating Crafty from the puzzle position:

I haven't completed my first attempt yet, but it looks difficult.

Oct-22-11  CHESSTTCAMPS: Actually, I found a clear win against Crafty on the 1st attempt. Have fun!
Oct-22-11  morfishine: <Phony Benoni> Very good points on the 'point' of this puzzle
Oct-22-11  Patriot: White is down the exchange and may be happy with a draw. It's important to note this, but it's much better to look for a win!

The rook looks almost trappable but at the very least, black can exchange it off for the bishop. 37.e6 fxe6? 38.Qd3 forks g6 and the rook. For example, 38...Rb2 39.Qxg6+ Kf8 40.Qg7+ Ke8 41.Qe7#. If just about anything else is played white can respond with 38.e7 and possibly 39.Qe5.

I thought this was much easier than yesterday's puzzle to find that first move.

Oct-22-11  morfishine: <CHESSTTCAMPS> Thanks for bringing in ole 'Crafty'...I wonder where <David2009> has gone to?...He was always providing this link :)
Oct-22-11  Old Wolf: White missed 38.Qc6! winning a piece due to the threat of Qe8+ and mate.

The only way that Black can prevent the mate is to play ..Qa1+ and ..Qxf6, but white meets ..Qa1+ with Bd1!! , so that after Qxf6, Bxe2 wins a whole rook.

Oct-22-11  Old Wolf: <Nilsson: After 37...c5! black probably can hold a draw.>

This loses quickly, just 38. bxc5!, then white has another passed pawn, and retains the threats of e7, Bxd5, and Kf1

Premium Chessgames Member
  Jimfromprovidence: Later on, worth attention is 51 Kc3!?, with the intention of walking the king along the dark squares to attack black's bishop.

Oct-22-11  Nilsson: Well the point should be That black also get a passed pawn, 38.bxc5 Bc6 but you are correct I missed 39.Qe5! thank you! /JN
Oct-22-11  sevenseaman: <Sastre> <46.Kf3 would have led to an easier win. For example, 46.Kf3 fxe3 47.Kxe3 Kg6 48.Kf4 Be8 49.Ke5 and Black can't stop White's king from reaching d8 and winning the bishop.>

A good idea that makes the win easier and faster.

I think the best idea for a quicker win came from <agb2002> that introduced <37. Qxc6 in lieu of 37. e7> I had some doubts but a busy <OCF> found time to quickly clear these.

A very lively discussion on a game that I initially thought would turn out to be a dull and drab affair.

Ultimately every complicated POTD becomes a <man vs the machine job> and most of the kinks do get sorted out.

Oct-22-11  TheBish: U Boensch vs Pinter, 1986

White to play (37.?) "Very Difficult"

Finally getting around to this on a busy Saturday. I dozed off after dinner (not typical, but went for a long run in the rain today) while watching the World Series. I woke up at the end of the 4th inning (remembering that the score was 1-0 St. Louis Cardinals), to discover that I had missed a big inning for both sides; seven runs scored, four for the Cards followed by three for the Texas Rangers! Now it's 8-5 St. Louis in the fifth (the hits keep coming), so it looks like the first to score 10 may win this.

Back to chess -- pawns are even, but Black is up an Exchange (rook for dark-squared bishop). However, the rook appears to be trapped, or at least "off-sides" (in a bad location). How can White take advantage? If 37. Kf1 Rxf2+ returns the Exchange, so maybe it has something to do with the e5-e6 push, so that if ...fxe6, Qd3 forks Re2 and g6 pawn (Qxg6+ with a forced mate). This is a little like a jigsaw puzzle that needs piecing together. Only not as many pieces. I'm focusing on 37. e6, threatening a passed pawn (e6-e7), which should win the game. That's it...

37. e6! fxe6

Weakens g6 to allow a fork and a nice finish, but what else? Anything else allows 38. e6-e7 (37...Rxf2 38. e7! or 37...d4 38. e7! (better than 38. exf7+) dxc3 39. e8=Q+ Kh7 40. Qxf7+ Kh6 41. Qg7#).

38. ♕d3 ♕a1+ 39. ♔h2 (or 39. ♗d1) ♕xf6

Since 39...♖xf2 40. ♕xg6+ ♔f8 41. ♕g7+ ♔e8 42. ♕e7# is curtains.

40. ♕xe2 and White is ahead a piece (bishop) for two pawns.

Wow, Albert Pujols just crushed a three-run homer for the Cards, now putting them up 11-6. Quite a change from last year's Series, when the SF Giants (my team) won with superb pitching and defense, and limited offense.

Oct-22-11  TheBish: Well, I neglected to give Black's best defense (stopping the passed pawn with Bb7-c8-d7 and then 39...Ra2!, going for opposite colored bishops, but no matter. White's pawns, bishop and king are all superior to Black's counterparts!
Oct-22-11  pericles of athens: pawn push!!!
Oct-23-11  M.Hassan: "Very Difficult" White to play 37.?
White is behind. has a Bishop for a Rook.

I thought pushing a pawn would be the good move to pave way for Queen to get close to back rank: 37.e6
Two lines may emerge:

38.Qd3 threatening taking g6 with check while attacking the Rook 38...........Qa1+
39.Kh2 Qxf6
White now has a Bishop for two pawns and there is no immediate win for a side although draw could be a possibility.


38.e7 Bd7
I can't see an immediate win in this case either but White has a passed pawn on rank 7 connected to f6 and as such, impose heavy burden on Black
