  FSR: Diamant in the Rough.
Nov-07-12  JohnAnthony: <FSR> just curious why you are repeating the pun
Nov-07-12  lost in space: Not repeating, this was a proposal of a pun (made in July 2012)
Nov-07-12  Abdel Irada: <JohnAnthony>: Perhaps you don't yet know that <FSR> is the <> Punster-In-Chief.

But since he still has 167 puns that have not yet been used, his light has yet fully to emerge from the bushel.

Nov-07-12  Abdel Irada: This looks almost like a helpmate. First, Black drives White's pieces to attacking squares (bishop from b3 to c2, queen from f4 to h4), then fatally weakens his kingside dark squares (not that he had much choice by then), and finally playing in the center and queenside in total disregard of the ominous cumulonimbus clouds stacking miles high over his kingside.

At least he had the wit to resign when struck (unexpectedly?) by lightning.

  FSR: These isolated queen pawn lines gone wrong for Black are amazing: a slight inaccuracy or two and he gets blown away.
Nov-07-12  Abdel Irada: <FSR>: That is in the nature of IQP lines.

As Nimzovich used to say, the isolated pawn is a static weakness and a dynamic strength. This implies that playing against them demands extreme prophylactic care to ensure that the dynamic attacking possibilities are neutralized before making any attempt to exploit long-term structural weaknesses.

In many cases, one notes that the most dangerous thing to allow the player with the isolated pawn to do is set up Horwitz bishops aimed at one's king. Note how many of these spectacular sacrificial brilliancies are predicated on possession of such bishops.

At some point, I'd like to unearth some of my old game scores to illustrate this point. As an attacking player in the mold of a Frank Marshall, I'm quite partial to such bishops. :-)

  FSR: The position after 13...Bb7 had occurred thrice before in the database, including a game just a month before. All three results occurred, most recently a win for Black. Games Like M Rodshtein vs A Diamant, 2009 Then Rodshtein plays 14.Qh4!N and mates Black into oblivion in just six more moves. Wow.
Nov-07-12  King Sacrificer: <Abdel Irada> and <FSR>. Thanks for the explanations about IQP. I couldn't fully understand the advantage of this and i reached this Wikipedia article to get the simple idea.

<"..However, the presence of open files in the important king and queen's-bishop (e and c) files as well as the outposts at e5 and c5 enable the player with the IQP very favourable attacking chances in the middlegame. Once the game reaches the endgame the isolated nature of the pawn becomes a greater weakness than these strengths. Therefore the player with the IQP must take advantage of the temporary strength before an endgame is reached.">

Nov-07-12  erniecohen: <parisattack: Yet another QGA where Black's position is dynamited with a well-timed d5>

Not really; after a simple 15...♗xd5, Black is fine.

Yessir; so it does appear!

Nov-07-12  Travis Bickle: I was thinking black had the defense h5, but that is negated very quickly with Qxh5! Whites 2 parallel bishops take care of the mate.

  kevin86: Diamont is NOT in the rough,he is in deep doo doo. lol
Nov-07-12  Vitinho: Bxd5 is refutation to Qh4 line.
15...Bxd5 16.Rad1 Ta7( or Te8,same line ) 17.Tfe1 Cc6 18.Bb3 Te8 or Td7 and black is safe.Black have to play very carefuly in this line.
