Apr-12-16  devere: Of course 38...Kg5?? was a losing move, and 38...Qxe3 would draw.

A cute winning line is 39.h4+ Kf5 40.Qd3+ Be4 41.Qd7+ Re6 42.b6 Qxe5 43.Rf1+ Bf3 44.b7 Qb8 45.Qc8 Qg3 46.Qc2+ Re4 47.a6 Ke6 48.a7

Now on 48...Re2 both Qxe2+ and Qg6+ are crushing.

Apr-12-16  saturn2: White can regain material and get a won rook ending by 39 h4 Kf5 40 Rf1 Bf3 41 QxQ KxQ 42 gxBf3

  agb2002: White has three pawns for a bishop.

White can achieve a won ending with 39.h4+ Kf5 (else 40.Qxf4) 40.Rf1 Bf3 41.Qxf4+ Kxf4 42.a6:

A) 42... Kxe5 43.gxf3 Kd6 (43... gxf3 44.Re1+ and 45.Rxe8) 44.fxg4 + - [3P].

B) 42... Rxe5 43.b6 and Black can't stop the pawns. For example, 43... Kg3 44.gxf3 gxf3 45.b7 Rb5 46.a7 Rxb7 48.a8=Q wins.

C) 42... Kg3 43.gxf3 gxf3 44.b6 wins (44... Rxe5 45.b7 Rb5 46.a7 Rxb7 47.a8=Q).

  whiteshark: <39.h4+!> I have come here to chew bubblegum and kick ass...and I'm all out of bubblegum.
Apr-12-16  not not: queen hanging so ph4 to push king away and then rf1 to kill the queen

and then 2 connected passers on queenside wins

Apr-12-16  not not: i missed bf3

is it possible to play, after black bf3, white queen to c5?

just holding him on ropes longer

Apr-12-16  dfcx: material is about even. but the black queen is pinned and only protected by its king.

39.h4+ Kf5
40.Rf1 create a new pin

A. 40...Rxe4? 41.Qxf4+ wins the queen

B. 40...Qxf1+ 41.Kxf1

C. 40...Bf3 41.Qxf4+ Kxf4 42.gxf3 gxf3 43.Re1 wins with the two passed pawn.

  Cheapo by the Dozen: This is slightly deeper than it first looks.

39 h4+ Kf5
40 Rf1

is fine. But a little better IMO is

39 h4+ Kf5
40 Qd3+ Ke6
41 Qd6+ Kf7
42 Rf1

That way White keeps all three advanced passed pawns.

  morfishine: <39.h4+> forces the Black King to either cut communication with the Black Queen, or onto a square where the Black Queen is pinned to the King

  lost in space: I found 39. h4 Kf5 40. Rf1 with significant material plus; in addition one of the passed pawns will queen
Apr-12-16  CHESSTTCAMPS: White has three pawns for a bishop, but stands to win decisive material because of the awkward position of the pinned black queen.

39.h4+! wins the queen by forced separation or pin.

A.39... Kxh4/Kh5/Kh6 40.Qxf4 wins

B.39... Kf5 40.Rf1 Qxf1+ 41.Kxf1 Rxe5 42.Qg5+ Ke4 43.Qxg4+ Ke3 44.Qxg6 with black's remaining force (K, R, & B) doomed to fork sequences.

B.1 40... g5 41.g3! Qxf1+ 42.Kxf1 Rxe5 43.Qg5+ is similar.

B.2 42... Ke6 43.Qxg6+ Kd7 (Kd5 44.Qg8+ wins bishop) 44.Qxg4+ wins black's last pawn with check.

Apr-12-16  CHESSTTCAMPS: Overlooked the 40... Bf3 defense, hopeless though it is.

  morfishine: <CHESSTTCAMPS> I wouldn't worry about it, IMO, its not much of an oversight when White has a forced win
Apr-12-16  mel gibson: Just checked it out on my computer.

Black made a mistake on 38...Kg5.

Black should have played 38...QxQ.

This then leads to a draw.

Apr-12-16  SaltiNeil: This was way easier than yesterday's.
Apr-12-16  mel gibson: These easy puzzles are not so charming as games where no one really makes a blunder but
brilliant moves from both sides lead to
a convincing win for one opponent.
Apr-12-16  YetAnotherAmateur: 39. h4 is obviously effective.

A) 39. ... Kxh4 or Kh5 or Kh6
40. Qxf4

B) 39. ... Kf5
40. Rf1 Qxf1+ (other legal moves allow Rxf4 with similar results) 41. Kxf1 and white's Q v B+R should allow one of white's passed pawns through to eventual victory.

Black has no good choices.

He cannot take the e pawn with the king or he loses his rook to a skewer. If he takes the e pawn with the rook, white pushes the a pawn. If he plays 43...Ra8, white pushes the e pawn.

  kevin86: Black has a grim choice: either move the king away from the queen or behind her and lose her by a pin. The text is a third choice, set up a dead losing ending.
Apr-12-16  Halldor: The King is the worst defender. Look for a combination when the King alone is defending a piece.

  Bubo bubo: 39.h4+ wins the queen: 39...Kf5 (otherwise the queen drops immediately) 40.Rf1.

<EDIT: Overlooked 40...Bf3 :-( >

Apr-12-16  latvalatvian: The king moves more solidly than any other piece, taking smaller steps. It would be better on ice.
Apr-12-16  leRevenant: <Penguincw: ... I couldn't find a good continuation.> I'm consoled that others have off-days too. I have plenty, but today wasn't one of them.
