|Mar-21-13|| ||agb2002: Black has a knight for a bishop.
White is about to play Ba4, relieving the pin.
This observation suggests 33... b3, blocking the diagonal a4-d1 so that the bishop can't protect the rook:
A) 34.axb3 Nd8 35.Rc5 Nxc6 - + [N vs P], (36.Ke2 Kf8 37.Kd3 Ke7 38.Kc4 Kd7 39.Kb5 Rb8+, etc.).
B) 34.Rc1(3,4) bxa2 and the rook can't stop the pawn and protect the bishop at the same time.
|Mar-21-13|| ||mira94: It was pretty easy for today, the pin wins: 1.b3 axb3 2.Nd8 and Rxc6|
|Mar-21-13|| ||lost in space: what a nice puzzle!
33...b3!! is closing the a4-c2 diagonal
After 33. axb3 Nd8 there is no defence for white, he will lose material as the defence Ba4 is not any longer defending c2.
|Mar-21-13|| ||Moonwalker: I looked at 33...b3 (for the wrong reasons) then looked at Nd8. Too bad I didn't consider the two moves in consort as I failed to see the simple defence 34.Ba4.|
I hope that, at least, while 33...Nd8 doesn't win, it doesn't lose either!
|Mar-21-13|| ||FSR: Looks pretty simple unless I'm missing something. 33...b3! 34.axb3 Nd8 wins, since White can no longer play Ba4. If 35.Rc5, 35...Nxc6 defends both of the attacked pawns.|
|Mar-21-13|| ||morfishine: Black would like to pin the White Bishop, but after 33...Nd8 White has 34.Ba4 and the rook is protected; Whats needed is to block the d1-a4 diagonal, interrupting the communication between
a4 & c2
<33...b3> Black calls on his foot soldier (the b-pawn) to launch a frontal attack <34.axb3> White must surrender a piece no matter what; <34...Nd8> Winning a piece and holding onto his pawns after 35.Rc5 Nxc6
|Mar-21-13|| ||amaurobius: <lost in space: what a nice puzzle!>|
I entirely agree. 33...b3 is not that hard to find but very attractive.
|Mar-21-13|| ||zb2cr: Found this one. My thoughts are pretty much along the lines given in detail by <notyetagm>, <Phony Benoni>, <Bartimeus>, <Patriot>, <Abdel Irada>, and others.|
|Mar-21-13|| ||awfulhangover: Easiest thursday ever!|
|Mar-21-13|| ||morfishine: <Moonwalker> On this comment <...I hope that, at least, while 33...Nd8 doesn't win, it doesn't lose either!> 33...Nd8 shouldn't lose, but White holds the draw with 34.Ba4|
|Mar-21-13|| ||mistreaver: Thursday. Black to play. Medium. 33?
White has problems on the c-file. However there is the saving move Ba4 if black goes for Nd8 immediatelly.
Not that hard to spot. Idea is to block the a4-d1 diagonal. White can resign.
34 axb3 Nd8 wins a piece
34 Rc4 bxa2 and black gets a new queen. Time to check.
Yep, simple and straightforward. 4/4
|Mar-21-13|| ||NM JRousselle: Does anybody know if White was in time trouble? The minor piece ending certainly did not favor White, but after b3!, it's over.|
|Mar-21-13|| ||Ezzy: 'Shilong's for Yue.'|
|Mar-21-13|| ||Oxspawn: Like <Moonwalker>. I thought Nd8 was a killer and never even saw Ba4, let alone the rebuttal. Not much consolation, but I assume that if the rooks swapped off, black could play largely on the dark squares and leave the white bishop out of the game?|
|Mar-21-13|| ||Herma48852: Okay, Black threatens 33...Nd8 attacking the pinned Bishop again. However, this can be defended with 34. Ba4. So the 33...b3! blocks the a4-d1 diagonal. Of course if White does not capture the P/b3, then Black will take on a2 and queen. So White must play 34. axb3 and 34...Nd8 and the Bishop is lost.|
|Mar-21-13|| ||doubledrooks: I voted for 33...b3, after which the White bishop cannot be saved. For example, 34. axb3 Nd8 35. Rd2 Nxc6.|
|Mar-21-13|| ||kevin86: Black throws in an intermezzo b3!!
After the white pawn takes,the bishop can no longer guard the rook by Ba4,so the clergy must be lost.

|Mar-21-13|| ||master of defence: Poor Li Shilong. The correct move was 33.Ba4! 33.Kf2? loses to b3! 34.axb3 Nd8 and the c6-bishop can't be saved.|
|Mar-21-13|| ||Alex56171: I didn't see 33.b4, but anyway it is an useless move.|
|Mar-21-13|| ||Abdel Irada: <Ezzy: 'Shilong's for Yue.'>|
Yue is pronounced ~"y-weh"; otherwise, not a bad pun.
|Mar-21-13|| ||TheTamale: <M.Hassan>, thanks for your comment. It clarified things for me immediately.|
|Mar-21-13|| ||radtop: Why not 33.Ba4?|
|Mar-21-13|| ||harish22: not sure why white was putting himself in pins. 33. Kf2 seems to have been a mistake. Ba4 was fine. Simply a blunder|
|Mar-22-13|| ||John Abraham: Not a difficult puzzle but it is kind of counter-intuitive to conceptualize pawns as having obstructive powers. Pawns are probably the most dynamic and interesting pieces in chess; a slight alteration in pawn structure can drastically alter the result of a game|
