| JohnBoy: Already by move 9 blacks position is seriously compromised. The white bishops are going to exert a lot of pressure on the h2-b8 and h3-c8 diagonals, the black kingside ishaving developmental difficulties, and the e file is open for white. It is hard to find a strategy for black at this point. does ...a6 and then ...b5 get one anywhere? Should ...e6 be played with the idea of ...Ne7-c8 and trying to hunker down on in defense of the d6 pawn? The first few moves here need to be seriously reviewed, as black has a greviously misconceived opening plan. |

| patzer2: I haven't analyzed 19. Rxe6+!! in any depth to see if Black might have any survival chances, but Black's futile struggles here certainly highlight the problems an opponent faces in trying to defend against these "demolition of pawn structure" tactics (in this case via the sacrifice on e3/e6 theme). |

| patzer2: If 39...Kb7, then 40. Rc6 is decisive. Play might continue 40...Rd8 (40...Qxd5 41. Qc8+ Ka7 42. Ra6#) 41. RxQ! RxQ 42. Rd7+ Kb6 43. Rxg7  . |

| Milo: How about 20...Nf5. Does that give black any hope? |
|

| JohnBoy: Actually, <patzer2>, I believe that 39...Kb7 is dealt with more brutally by 40.Qc8+ Ka7 41.Rc6. White then doesn't need to give up the Q and maintains several mate threats. But we certainly agree that this is a pretty compromised position for black. |

| themindset: interestingly, crafty is screams for 17.Be6+ with a huge + for white. but rates the 19.Rxe6 sac as roughly equal (with best play, which black did not provide in this game). |

| patzer2: <themindset> and <crafty> Thanks for pointing out an even better demolition of pawn structure combination with 17. Bxe6!! <JohnBoy> Thanks for the alternative win after 39...Kb7. |

| patzer2: After 19. Rxe6!? fxe6 20. Bxe6, Fritz 8 indicates Black equalizes with the surprise defensive move 20...Rb6! =. Play might continue 20...Rb6! 21. Bxb6 Qxb6 22. Nxd5 Qc6 23. Nc7+ Kd8 24. Qxc6 Nexc6 25. Nxb5 Rf8 26. d5 Ne5 27. Nxa7 Nxf3 28. Nc6+ Nxc6 29. dxc6+ Nd4 30. Bc4 Rxf2  when Black's extra piece and active development appear sufficient to compensate for a three pawn deficit. |

| patzer2: White misplays the attack with 23. Bd3?!, as 23...Qc8 = gives Black equality. Better is 23. Bxe7! Kxe7 (23...Qxe7 24. Qc8+ Qd8 25. Bf7+ Ke7 26. Re1+ Kxf7 27. Qxd8 ) 24. Bh3! , when White wins with three pawns for the piece due to Black's exposed King position and awkwardly placed pieces. |
