dell'autostallo The theme is one of the most effective methods of defense to force a draw. Is to restrict the movement of their king and paralysis are not rare and sacrifices of one or more pieces to achieve this goal. A study by Berger in 1980 illustrates this theme in an exemplary manner.
White to move and draw. At first glance, the white seems doomed: her king would not have time to stop the pawn of black tower, but in fact this is the next maneuver to force the deadlock. 1.f4! The only Rc7 , alternatives 1 ... a5 3.h5 2.h4 gxf4 gxh5 4. gxh5 6.h7 a4 5.h6 a3 a2 7. h8 = Q + and 1 ... a5 2.h4 a4 3.h5 a3 gxh5 4.fxg5 a2 5.g6 6.g7 a1 = D 7. g8 = Q + RB7 8. DF7 9.De6 RC8 + + RB7 10.gxh5 are advantageous for the white. 2.fxg5 and now White can force a draw regardless of the game thanks to the moves of black 3.Rg3 4.Rh4 and 5.g3.
autostallo But the stuff is not just for composers such cases may occur also in practice. We see a recent example.
