Pin (2)

The second sample from the book features:
Advantage in Development.

Pin can be especially effective when our opponent’s king stays in the center. We can use the central lines for our heavy pieces that can be easily opened, as well as the power of the bishops and the queen. For the sake of opening the position of a non-castled king pawns and even pieces are often sacrificed:

Bruzon Batista,L (2607) - Flores,Di (2558)
II ch-Ibero-Americano Gp B Morelia MEX (2), 16.02.2008
1.d4 g6 2.Nf3 Bg7 3.e4 d6 4.Nc3 Nd7 5.Bc4 e6 6.0–0 a6 7.a4 b6 8.Re1 Bb7 9.e5! Black played too passively in the opening, and White starts to open lines against his king in the center. 9…dxe5


10.d5 exd5 11.Nxd5 Ne7 12.Bg5 Bxd5 13.Bxd5 Rb8 14.Bc6 f6 15.Bxf6! "With so many pins and a development advantage, the tactical ideas are clearly justified," states the Brazilian GM Vescovi [15.Nxe5 fxe5 is another way to keep the king in the center. After: 16.Qg4 Nxc6 17.Bxd8 Nxd8 18.Rad1±


Black has three light pieces for a queen, which usually favours the side with the pieces. However here black king cannot find a save heaven, and White is much better. The way that Bruzon chose is more clear-cut, and should have led to success.] 15...Bxf6 16.Nxe5 Bxe5 17.Rxe5 Rf8 18.Qd5?! But here he went astray. Better was: [18.Qg4! Rf5 (18...Rf6 19.Re6 Kf8 20.Bxd7+-) 19.Rae1 Rxe5 20.Rxe5


with the idea Qg4-e6-g8 mate and this should have led to a win (Vescovi). In this line White exchanges one of his active rooks, but for the only active Black’s piece. Both knights now are partially paralyzed due to the pin, and from this suffer all other Black’s pieces. 18.Re6!? was reasonable, too- 18…Rf7 19.Qd2 Kf8 20.Bxd7+-It is quite obvious that Black has to part with his superfluous material. In such situations we must try to take it back (or even win) material without loosening the grip that we have, and giving in return the initiative.] 18...Rf7 19.Rae1 Kf8 The queen on d5 is hanging, and Black manages to exchange some active pieces and get relief-20.Qxd7 Nxc6 21.Qxc6


White is still better but Black managed to save half a point with stubborn defense later…Ѕ–Ѕ

    the example clearly shows how white was able to sacrifice a piece and know he was going to be immediately getting it back because of the pins, and shows how deadly a pin can be if the opponant doesn't play carefully, a very important point that can be very useful in a lot of practical games, so ya, i think it does bring home the point.

    I think people just dont like the fact that you'r not using a clipboard and are too lazy to play the moves out themselves

    Why do you think so? White was completely winning even a piece down thanks to the pin.

    Kind of a strange example that fails to bring home your point.
