48 ♗d3-f5! 1-0 <<obstruction: e5->h8>


click for larger view

Wang Hao's excellent <OBSTRUCTION> shot 48 ♗d3-f5! 1-0 wins the game *instantly* by <PREVENTING> Black from <LINE-OPENING> the critical e5->h8 diagonal in order for the Black e5-bishop to <GAIN CONTROL OVER THE PROMOTION SQUARE> the h8-sq of the White h6-passer.

Jul-27-13  Doniez: Yes, your analisys is correct but I can't see no defence after 47.fxe6 . If 47...f5 to open tthe long black diagonal, then immediately 48.Kxc3 and Black looses his Bishop. So it seems that after move 47 Fridman had NO chances to open the a1 h8 diagonal, letting White h pawn queening. Is there any other possible defence for Black that I can't see?
Jul-27-13  Calar: <Doniez> No, there isn't. Black was however lost some moves earlier, seeing as how last few moves are literally forced.
Jul-27-13  Doniez: Ok <Calar> , I really enjoyed this match of Wang Hao and he needed a win after the last performance not at his usual levels...

Yes, Black was lost before 48 ♗d3-f5! 1-0.

I just annotated it because it is a very simple and crystal-clear example of the <OBSTRUCTION> theme.

A good example to learn from and what to look for in your *own* games. :-)

Jul-27-13  Doniez: <notyetagm> For sure I will use the tactical theme of "obstruction" in my games and your comments are always very clear and full of good ideas, especially for patzers like me

That's why I do this, for <INSTRUCTIVE> value.

<perfidious> seems to think that I do this for some evil reason, that I enjoy watching players blunder and lose.

In fact, I *do* enjoy watching players blunder and lose because it gives me great examples to learn from so I do not make the same mistake in *my* games. :-)

For example, who will forget about leaving their rooks <UNPROTECTED> with queens on the board after seeing Wang Hao's *horrendous* <BLUNDER> 25 ... ♖b2-a2?? yesterday?

Yes, it's the smart person who learns from the <BLUNDERS> of *others*, not by learning from his own failures.

Jul-29-13  Ulhumbrus: Instead of 26...f6 it is better for Black to weaken himself on the black squares by 26...g6 because White has no dark squared bishop and the white king's bishop is obstructed by Black's pawns
