Jan-07-15  abuzic: 27.?
27.Be8 Nxe8 28.Qxd5 Rh7 29.Qc5+ Kg8 30.Qe7 Rg7 31.Qxe8+ Kh7 32.Rb8 and no escape, for example 32...g4 33.Qh8+ Kg6 34.f5+ Kf6 35.Qd8#

  Oxspawn: I propose
27. Be6 threatening Rf7+ and after the king moves Qg8 when the black knight cannot intervene if the king is on e8 and can only intervene ineffectively if the king is on g8. So it seems to me that

27.Be6 fxe6 is forced (leaving out 27. Qg1+ which only seems to capture a pawn on e3 after the king moves to a2)

28. Rb8+ Ne8
29. Qc5+ Kg7
30. Rb7+ Kg8
31. Qd5+ Kf8
32. Qf7#

One other line to look at
28. Rb8+ Ke7
29. Qc7+ Nd7
30. Rxh8
White has rook for bishop. I donít see too clearly here but I think the black queen cannot intervene quickly enough to stop Rd7 followed by QxN and a messy mate somewhere nearby (without the board in front of me I am losing vision.)

Jan-07-15  morfishine: This one required some work, progressing thru checks then searching for 'other' moves. White must produce something decisive and relatively quick; otherwise if allowed, Black gets his Queen to <f1> where he has perpetual check; but that takes two moves

<27.Be6> Wins on the spot; immediate threat is 28.Rxf7+; The Bishop can't be taken due to 27...fxe6 28.Qd8+ Ne8 29.Qe7+ Kg8 30.Qxe8#

Defending the f-pawn with 27...Rh7 fails to 28. Qd8+ Ne8 29.Qe7+ Kg7 30.Qxf7+ Kh8 and White has three moves to choose for mate

*****

  CHESSTTCAMPS: White has B+P for a N, and all pieces are poised for an attack on the BK, while black's defending N and R are passive, and the BQ is unavailable for defense. A typical novice continuation such as 27.Qd8+ Kg7 would give black a key tempo for defense. This should be winning anyway because white's advantage is so great. However, the most efficient breakthrough is

27.Be6! striking immediately at the f7 weakness:

A) 27... fxe6 28.Qd8+ Ne8 (Kg7 29.Rxf7#) 29.Qe7+ Kg8 30.Qf7#

B) 27... Rh7 28.Qd8+ Ne8 (Kg7 29.Rxf7#) 29.Qe7+ Kg8 30.Qxe8+ Kg7 31.Rxf7#

C) 27... Kg7 28.Rxf7+ Kg8 29.Qd8+ Ne8 30.Qxe8#

D) 27... Ne8 28.Rxf7+ Kg8 29.Qd8 forcing mate.

Black can insert spite checks by the queen in any of the above lines, to no avail.

  varishnakov: 27.B-K6 and if 27...PxB 28.Q-Q8+ N-K1 29.Q-K7+ with

mate to follow

Jan-07-15  TheaN: 7 January 2015 <27.?>

White has a strong attack going over the ranks, but the bishop is not well placed. If white immediately tries to make the position work, i.e. 27.Qd8+? Kg7 or 27.Qc5+?! Kg7 28.Be6 Rf8 black still holds. The last variation however, does contain the move that allows white to retain the initiative on the cornered black king and also keep the h8-rook out of play.

If the bishop is not well placed, we move him so that both the bishop and the rook gain more scope: <27.Be6!>, Δ Rxf7+.

Key to this move is that it opens up the semi-open 7th rank. After <27....fxe6? 28.Qc5+ Kg8 (Ke8 29.Qc8#) 29.Qc8+ Ne8 30.Qxe8# 1-0<>> white demonstrates the bishop is immune. But what can black do against Rxf7+ otherwise? The spite checks on h1 or g1 don't give the queen more space and black is back at square one after 27....Qg1+/Qh1+ 28.Ka2 .

The hopeless idea to block the back rank <27....Ne8<>> allows white to switch moves: <28.Rxf7+ Kg8 29.Rd7+ Kf8 30.Qc5+ Nd6 31.Qxd6+ Ke8 32.Bf7#<>>. Perhaps the most sensible reply would be <27....Rh7> to protect f7, but the Qc5-c8 manouver still works and leads to mate: <28.Qc5+ Kg8 (Ke8 29.Qc8#; Kg7 29.Rxf7+ Kg8 30.Qf8#) 29.Qc8+ Ne8 30.Qxe8+ Kg7 31.Rxf7# 1-0>.

  Once: Chess is primarily a war game. Two armies fight against each other. There is thud and blunder, death and destruction, heroism and dogged defence.

But there are some things that we do in chess that don't feel much like a war. Sometimes it feels more like football. That's football as in the game played with a ball and some feet, which some parts of the world insist on calling sawcker.

Picture the scene. You are the manager of Accrington Stanley FC (a football/ sawcker team based in northern Blighty). You are playing Tranmere Rovers in League Two, which rather confusingly isn't the second division, but the fourth. Don't ask.

It is part way through the second half and you are having a torrid time. Your opponents have a twinkle-toed striker who is dancing past your back four as if they weren't there. He hasn't scored yet, but it's only a matter of time.

It is at this point that you can do something in football that you can't easily do in a battle. You can swap one of your players for one of your opponent's players. In effect, you can trade in a grizzled war-horse of a defender for their star.

You call your number three over to the manager's dugout. Vinnie Hacker Smith. He's as a hard as nails, but as slow as a carthorse. His knees have long since gone, but you keep him in the team because he has a very particular set of skills - a line since stolen by Liam Neeson in Taken.

You ask Vinnie to take out their star attacker. Flatten him. Get him stretchered off. It doesn't matter if Vinnie gets injured in the process, or even red-carded. You are perfectly happy to trade him for twinkle toes.

And so it is with today's POTD. The white bishop isn't doing much, so white offers to trade it for the much more valuable black f7 pawn.

That may not be cricket, but it's certainly football.

Jan-07-15  TheaN: No flaws here, but I was so focused on the Qc5-c8-e8 manouver I missed Qd8-e7-e8 essentially does the same. Both win, and I guess it's a matter of preference what you want to play. The distinctive lines would have been more interesting if black had control over c5-f8 or d8.

  Penguincw: And I go for a losing combination, again: 27.Qd8+ Ne8 28.Be6. After 28...Qg1+ 29.Ka1 Rxd8, I recommend 30.Rxf7+ Kh8 31.Rxf6 (any) and 0-1 for white.

  OhioChessFan: I went with g5 also, as I considered the Knight, not the f Pawn, as the key to Black's defense. I forgot Lasker's admonition to find a better move after you've found a good move.
Jan-07-15  KingsPawns: Black is doomed with a good for nothing Rook and a Queen that forgot to protect her King. But white needs a quick way to get to the King before Black can develop it's pieces into a better defense. And, with this in mind, Be6 is the way to go!

  kevin86: Black opened the second file andwhite will mate on it.
Jan-07-15  bachiller: 27. Be6

One small step for a bishop, one giant leap for the white army.

Victoria! The war is over, the moon is yours.

P.S. The contenders' names add some fun to the POTD when read in Spanish ('Guerrero' means 'warrior', so the game is prone to a pun such as 'Victoria frente a un Guerrero desarmado')

Jan-07-15  Bycotron: White to play at move 27, this is my thought process.

My rook controls the 7th rank and my queen has access to d8, I would love to be able to check mate black's king on the 8th rank by using these two facts. Unfortunately, my bishop on d7 blocks my rook's control of key squares and black's own pawn of f7 allows the king to escape at g7.

Is there any move that removes my own bishop from blocking the mate and removes black's f7 pawn? Yes!

27. Be6! is easy to spot once we know what we're trying to accomplish.

if 27...fxe6 28.Qd8+ Ne8 29. Qe7+ Kg8 30.Qf7#

White threatens Rxf7+ and Qd8+ mating if black doesn't take the e6 bishop. Queen checks don't help black's situation so the only defense to consider is 27...Rh7 then 28.Qd8+ Ne8 (Kg7 Rxf7+) 29.Qe7+ with Qxe8 next and it's all over.

Upon looking the game over, I have to admit I thought black had a substantial advantage out of the opening but played very passively (eg 19...Ng8) and really asked for a good pounding. White gave him what he asked for!

Jan-07-15  schachfuchs: I dont get the idea of 19....Ng8 -
I think it's not only ? but ??

Maybe he touched the knight without saying 'J'adoube' ?! ;-)

Jan-07-15  Cheapo by the Dozen: <schachfuchs>, I'm guessing the idea is that the knight jumped before it was pushed by g5. But yeah -- that didn't work out well.
Jan-07-15  Castleinthesky: It's a good week when I get a Wednesday. It took a while, but the Bishop takes the day.
Jan-07-15  PerpetuallyChecked: Sacrificing the bishop to get a stranglehold on the 7th rank seemed like a very thematic approach, and I was able to follow through to the game continuation. Wednesdays are often my tipping point, so I'm happy!
Jan-07-15  Amarande: A cursory observation showed Black threatens no perpetual and that neither the direct violence of 27 Rxf7+ nor the simple check 27 Qd8+ leads anywhere (27 Qd8+ Kg7 and I can't play 29 Be6 because my Queen is hanging, otherwise it would be good!).

Didn't analyse it out, simply noticed that 27 Be6! should do the trick, since Rxf7+ promises to be a rock crusher and Black can't take the Bishop (although it turns out he did) because 28 Qd8+ will then be fatal. The check at f7 can be prevented only by Rh7 but then 28 Qd8+ forces the King to obstruct the protection of the pawn, with mate to follow.

Jan-07-15  King.Arthur.Brazil: I followed Varishnakov, directly. 7th and 8th rank is usual theme for Q+R mates! Not much thincking!

  Bubo bubo: White opens the 7th rank by playing 27.Be6!, and Black has no sufficient defense against Rxf7, as 27...fxe6 and 27...Rh7 both fail to 28.Qd8+.
Jan-07-15  ku0826: Lasker's admonition to find a better move after you've found a good move.It means deep and wide reading.
Jan-07-15  stst: late... can think only of one main line:

27.Be6....

IF (A)..... Kg7
28. Rxf7 Kg8
29. Qd8#

IF (B) ..... gxe6
28. Qd8+ Ne8
29. Qe7 Kg8
30. Qg7#

In all cases, critical to lock the Black K within the corner, not allowing the 6th rank Pawns to get loose.

Jan-07-15  stst: typo for my variant (B)

gxe6 meant to be fxe6 to be exact, sorry
