Qg8+!!</b><br />Already down in material, White sacrifices the Queen! And Black has to accept the sacrifice, otherwise:<br />1. ... Kg6 2. Qxg7#<br />1. ... Kh6 2. Qh8+! Kg6 3. Qxg7#<br />1. ... Kxg8 <b>2. Rxg7+!!</b><br />And now, Black cannot capture the Rook, because it leads to draw by stalemate!<br />2. ... Qxg7 (stalemate)<br />2. ... Kxg7 (stalemate)<br />But the King will never get rid of this Rook...<br />2. ... Kh8 3. Rh7+!<br />3. ... Kxh7 (stalemate)<br />3. ... Kg8 4. Rg7+! Kf8 5. Rf7+! Ke8 6. Re7+! Kd8 7. Rd7+! Kc8 8. Rc7+! Kb8 9. Rb7+! Ka8 10. Ra7+! Kb8 11. Rb7+!<br />It never ends: it's a draw by perpetual check (or stalemate, if Black captures the Rook at any moment).<br /><br />In the actual game, <b>49. Qg8+!!</b> Kxg8 <b>50. Rxg7+!!</b>, and the players agreed to a draw.<br /><br />Note: <b>1. Qh8+!!</b> also works:<br /><b>1. Qh8+!!</b> Kxh8 2. Rf8+ Kh7 3. Rh8+ Kg6 4. Rh6+ Kf7 5. Rf6+ Ke7 <b>6. Rf7+!!</b> Ke8 7.

Mas as Brancas podem dar xeque infinitamente, então é empate de qualquer forma.<br /><br />:-)Unknownhttps://www.blogger.com/profile/07227239378179182300noreply@blogger.com
