threats by Black. The thematic try with the offer of a rook sacrifice with its
return after 5.Re2? is refuted by Black with his own offer of a knight
sacrifice after 5...Ne5!, in order to gain a winning position at the end of
the combination. Even 5.b8Q? is not enough, which leads to mate. White still
has the opportunity to attack the rook with a bishop. However, the try 5.Bd8?
leads to a losing position. Till after the inserted 5.Bf2! Rh3, the thematic
sacrifice of a rook with its return after 6.Re2! comes, which can no longer be
refused. Black still tries to mislead White after 8...Rf3+, so that after the
wrong move 9.Ke4? he can also gain his new queen with the fork. However, after
the only right king's move 9.Ke5, White draws, e.g.: 9...Nxh7 10.b8Q =, or 9...
