Neither 1.Nd5 nor 1,Ne4 wins.Correct is 1.f5
(1) 1….. gxf5 gives a check post (pun intended) for N at h5 2.Ne4 Qxe1 3.Nxf6+ Kg7 4.Nh5+ Kg6 5.Nf4+ followed by 6.Ra1xe1
(2) 1…. Bxf5 2.Ne4 Qxe1 3.Nxf6+ Kg7 4.Ra1xe1 Kxf6 g4 wins the pinned B.
(3) 1…. Bc8 2.fxg6 Kg7(2… Bg7 3.gxf7+) 3.Rxf6 Kxf6 4.Ne4+ winning Q.
I think Nd5 attacking the exposed Q and the f6 B with a check , relieving the pin and making c6 a future target works out to whites advantage.
1ND5 AFTER QUEEN EXCHANGE BLACK’S PAWN POSITION BECOMES HORRIBLE.
nd5 rd5
qa5 ra5
bc6 rc8 doesn’t look good
f5 gf5
ne4 wins a piece
