Qxc5 2.Nxc5 Nxc5 3.Bh6 Nxb3 4.axb3 Nd7 5.Bxf8 Rxf8 6.Qe4 b6 interesting PV first up wouldn't you say? It seems that Fritz has already totally refuted 1.Rxc5 Nxc5 > +- (2.88) Depth: 16/47 01:31:32 3406222kN >1.Rxc5-- > +- (2.56) Depth: 17/46 01:37:46 3618726kN >1.Rxc5-- > +- (2.56) Depth: 17/47 01:46:03 3887272kN >1.Rxc5! > +- (2.88) Depth: 18/47 02:29:13 5333982kN >1.Rxc5!

Qxe6 2.Nd5 Kd8 3.Bg4 Qe5 4.f4 Qxb2 5.Bxd7 Bxd7 6.Rb1 Qxa2 it seems this is just a partial PV?
