PQR Qhi
Black is helpless. The KtP is backwards, h i s King s side is disorganised and his King bereft of refuge Alekhin wins methodically by making himself safe and slowly manoeuvring his opponent into a Zugzwang. This additional weakness was forced, for Black could not hide his Rook on KRi all the time. The Rook is exchanged o prevent KR-Kt3, w here White cannot exchange it without uniting the Black Pawns. Probably not necessary at this moment, but White can force it at any time by R-KKt3.
