 | | notyetagm: The <exchange on the d7-pinning square>, 26  xd7! xd7 27 d1 h8 28  a4! and Black resigns.Why? Because 28 a4! adds yet another attacker to the fully pinned and <loose> (2 attackers, 2 defenders) d7-rook, putting it en prise. If Black meets this threat by defending the d7-rook again the only way he can with 28 ... e7, then White wins a piece with 29 c6+, the White queen staying in contact with the Black d7-rook while she drives off the c8-king defender (<remove the guard>). That is, 28 ... e7 29 c6+  b8 30 xd7 xd7 31 xd7 and White has an extra bishop. 28 a4! is the move that Mamedyarov visualized when he played 26 xd7!. <The White queen gains access to the critical c6-square for free (with tempo) by attacking the loose d7-rook.> It is this tactical point that Tregubov missed but Mamedyarov saw. |

 | | Gilmoy: This game follows "well-known" theory through 8..Na6 (>100 games in the database), and "less-known" theory through 11..O-O-O (~10 games). The games histogram at each move is: (2337) 3..c6
------
(311) 4.e4 -- this must be Marshall's gambit
(245) 4..dxe4 5.Nxe4
(224) 5..Bxb4+
(192) 6.Bd2
(187) 6..Qxd4 7.Bxb4 Qxe4+
(161) 8.Be2
(105) 8..Na6

(34) 9.Bd6
( 9) 9..e5 10.Nf3 Bg4
( 8) 11.O-O O-O-O
( 2) 12.b4 Nf6
------
( 1) 13.c5= N Vitiugov vs D Frolyanov, 2006 Mamedyarov diverges with 13.Re1. 12.b4 amounts to a 2nd pawn sac, as White can't (or chooses not to) outrace Black's Q+N double on it. White's compensation is half-open b+c files to Black's K, with free tempi as he kicks Black's Q around. GMs rarely stumble into 2-pawn gambits, so Mamedyarov must have done some deep home prep for this line. <mistreaver> is right: he's just better prepared. |

| | notyetagm: Position after 28 a3-a4! 1-0
click for larger viewThe game continuation would have been 28 ... f6-e7 29 a4-c6+, <REMOVING THE GUARD> of the 3-3 <LOOSE> Black d7-rook by <DRIVING OFF> the Black c8-king defender. (VAR) Position after 28 ... f6-e7 29 a4-c6+ <remove the guard>
click for larger viewI just love how Mamedyarov (White) uses the <PIN> against the Black c8-king to create a <LOOSE> piece (Black d7-rook) and then exploits the <LOOSENESS> aspect and -NOT- the <PINNESS> aspect to win material. |

click for larger viewAn amazingly simple winning formula by Mamedyarov:
1) Create a powerful <PIN AGAINST THE KING> 
click for larger view2) <REINFORCE THE PIN> 
click for larger view3) As the <PINNED> piece is also <LOOSE>, and <LPDO>, win the <PINNED> -AND- <LOOSE> piece using the underrated (-- Heisman) <REMOVAL OF THE GUARD>
