Главный план белых Bc3+ Rxc3#, но мешают Pb3 и Pb4.
1.Re2+! Ka2 2.b5! (zz) Rxa4 3.Sc4+ (вот почему ладья первым ходом пошла на e2) Kxb3.
В результате первого предварительного плана Pb4 ушла, предоставив Ba5 возможность хода на с3, а Pb3 аннигилирована.
Вторым предварительным планом возвращаем фигуры на исходную позицию.
4.Re3+ Ka2 5.Ra3+ Rxa3 6.Sd2+ Rb3 7.Qf8! Ka1 8.Qa3+ Rxa3
