| Oct-07-14 | | The17thPawn: Anyone who can win playing Philidor's defense against strong opposition deserves full marks. I usually found myself struggling for equality the entire game when assaying the Philidor. |

| Oct-07-14 | | Cheapo by the Dozen: I'm trying to figure out what White's plan or goal was in the opening. Anybody have an idea? |

| Oct-07-14 | | waustad: Both could be playing in the World Junior Champs now, but Bok is the only one who chose to. He's the #3 Dutch junior after Giri and van Kampen (who is also in Pune). |

 | | An Englishman: Good Evening: Impressive to see such an attack erupt so quickly from a Philidor--rather like seeing a sudden avalanche in the middle of the desert. |

 | | Once: Great game by black. He progressively took over more and more control in the centre until he was able to overwhelm the black kingside. The white moves that I didn't care for were 9. dxe5 and the plan of Nh4-Nf5. That just seemed to hand the centre over to black for no compensation. When black played e4 and Qe5 I was expecting white to look for a way to evict the black queen from such a strong central post. Instead, white allows e5 to become a black staging post. Four of black's pieces use e5 as a layover en route to somewhere else. Nice mating combination at the end.
Enjoyable game to play through and a great choice for GOTD. Thanks! |

| | Once: <mravikiran: what is White's best move after 23... Re5> Resigns. Probably.
Fritize can't find anything to save white. If he defends against the mate, black grabs the Bc5. Actually, the best move probably was 24. Bxf8. White has a lost position, but there is just a chance that his opponent won't see the mate in 3 starting with 24...Qh3+. And if Black doesn't spot the mate white is back in the game. What has white got to lose? He plays 24. Bxf8 and crosses his fingers that black doesn't pick up his queen and stick it on h3. It's a better gamble than resigns - on the grounds that some hope is better than no hope at all. |

| Oct-07-14 | | morfishine: I was introduced to a new chess term yesterday (new to me at least) by my friend <cro777>: "Center of Gravity" or COG Though I don't understand COG perfectly, I can say in chess, COG pertains to the most important aspect(s) of a position at a given point in time. As <Once> points out, White's
plan of exchanging his Knight on <f5> for Bishop is positionally flawed handing over <e5> to Black. One could argue that <e5> is the COG and that Black having full control
over this square, also has control of the COG of the position. Or vice-versa, White has
lost the COG in his position and is in fact wobbling and teetering and about to lose his
balance and fall over outright.
Its easy to see the net result of securing then utilizing COG as Black now finds it relatively easy to mass his forces and obtain a material superiority at the point of
attack. The position after <23.Re5> pretty much says it all:

Black has 4 pieces including his Queen positioned near the enemy King. No fancy flank attack here: Hey Diddle, Diddle, right up the middle ***** |

| | Once: Morf - great post!
I find the concept of a chess centre of gravity to be fascinating. It sometimes seems that the centre of gravity shifts during a game. If we look at the opening, we see that black is playing for the traditional Philidor "strong point" idea. His goal is to hold a pawn at e5. Nothing bad can happen if he can hang on to that pawn. It's what Nimzowich would call "overprotection". 
click for larger viewThis isn't as dynamic as the Sicilian's unbalancing of the position with c5 or the French/ Caro Kann plan of preparing for a d5 push. Black abandons his strong point plan when white voluntarily gives up the centre. Then he plays 13...e4. 
click for larger viewAnd now we see one of the benefits of overprotection. When the thing you are overprotecting has gone, you still have a lot of pieces pointing at that newly empty square. Or pieces that can get to that square quickly. The centre of gravity has drifted southwards. But the only point of controlling the centre is to allow you to get at the enemy king (eventually), so black than shifts the centre of gravity again to jump down white's throat: 
click for larger viewWe have a symphony in the key of e5 - overprotect a pawn on e5, push that pawn, use e5 as a staging post, forget e5 when the action switches to the kingside. |

 | | AylerKupp: <morfishine> Although I haven't heard it called that before, the concept of a COG is not new. Often a game revolves around a certain square, and domination of that square determines who wins, who loses, or whether the game is drawn. Here is an example that you're familiar with but others might not be: Team White vs Team Black, 2013. The game's name clearly indicates what the COG is. |

| Oct-07-14 | | kevin86: Nice queen sac leads to mate. The mate has an Arabian touch to it. |
|
| Oct-07-14 | | Castleinthesky: Youngsters, Rappaport is 18 with a 2700+ rating and Bok is 19, the future of chess! An "A" on the Rappaport card. |
|
| Oct-07-14 | | BOSTER: <Karposian:What a wonderful player Rapport is>. I hope somebody will play 6.Bxf7+ sometimes. |
|

 | | Domdaniel: The nice thing about 23...Re5 is that it is deceptive: it doesn't obviously threaten a forced mate. It hits the White Bishop and seemingly threatens to free the Rf8, encouraging White to take it at once. |

| Oct-07-14 | | Dragi: It is not Philidor but Pirc Defense ! |
|
Oct-07-14
 | | perfidious: <Dragi: It is not Philidor but Pirc Defense !> If the position after Black's fourth move had arisen after the plausible alternative move order 1.e4 e5 2.Nf3 d6 3.d4 Nf6 4.Nc3 Nbd7, no-one would refer to that as a Pirc. Ah do bleeve White failed this exam. |
|
| Oct-07-14 | | morfishine: <Dragi> I sympathize with your exclam <It is not Philidor but Pirc Defense!> Too often, game openings are categorized using transposition. Frequently I've argued that many such games should be categorized using the early move order. Since the Pirc defense requires <3...g6> followed by <4...Bg7> (as stipulated by the originator of the defense, Vasja Pirc), unfortunately, this is a true transposition into a Philidor. Of note, Pirc's idea was simple: provide open diagonals for both Black's Bishops. Black's WSB has the c8-h3 diagonal while the DSB has the h8-a1 diagonal ***** |

| | Once: In days of old when knights were bold, the Philidor began with 1. e4 e5 2. Nf3 d6 But this largely fell out of fashion because white gets an easy game. In particular, after 3. d4 it is hard for black to maintain his strong point on e5. The more modern way to get to a Philidor position is to play 1...d6 first. Black holds back the move e5 until he can play it safely. Black can then build what is known as the Hanham variation, with d6, e5, Nf6, Nbd7 and Be7. More about it here: possibly written by our very own <FSR>. http://en.wikipedia.org/wiki/Philid...
On the other hand, a pirc is defined by the move g6. But again, black players often transpose to other variations depending on what white does. The 1...d6 complex of openings is a fascinating little group. Not really dynamic enough for the highest levels of chess perhaps. But then most of don't live in the highest levels of chess! |

| | Domdaniel: Sometimes the problems raised by opening classification can't really be solved: it's a matter of taste, or of convention.
In the case of 1...d6 systems, after 1.e4 or 1.d4, the simplest solution is to call it a Pirc if Black plays an early ...g6. Of course, after ...g6, transpositions to the Modern (usually 1...g6) or King's Indian (with a White c4) may be possible.
When Black plays ...e5 instead of ...g6 (often with subsequent ...Be7) then it's a Philidor.
The variation 1.e4 d6 2.d4 e5 has recently been called the 'Lion'. |
