1.Nd5 is fairly obvious- the hard part (for me at least) is to see the knight fork from c7 as being good if black takes at e6 in response:
1. Nd5 Re6 2. Re6 Qe6 3. Nc7
Now, my concern is Qe2 attacking the rook, but white has an adequate reply with Rd7:
3. …..Qe2 4. Rd7 and black is going to lose the rook entirely since there are no perpetuals starting with Qe1+. Best in this line looks to be 3. …Be7, and white just wins a piece outright with Nxe6. So, let’s look at the other defenses at move 1 for black:
1. Nd5 Rg7 2. e7 g5 (what else?) 3. Qd4 and I don’t see how black avoids losing a piece, and probably an entire rook. Or
1. Nd5 Ree8 2. Nf6 Kg7 3. Ne8 Re8 4. e7 again losing a rook at minimum.
So, the best looks to be to just to try to concede the exchange:
1. Nd5 Rae8 2. Ne7 Re7 3. Qf6 and white’s edge should be decisive.
Qf6
1. Nd5 Rxe6 (1…. Rg7 2. e7) 2. Rxe6 Qxe6 3. Nxc7 +-.
Nd5
Spoiler :
Nd5! wins the exchange!
Nd5 Rxe6 (any other rook move e7 or Nf6+ will be hard to deal with)
RxR QxR
Nxc7
1. Nd5 Rxe6 (1. … Re8 2. Nf6+ wins rook) 2. Rxe6 Qxe6 3. Nf6+ Kg7/f7 (3. … Kh8 4. Qxh7#) 4. Rd7+ Qxd7 5. Nxd7 1-0
Best is Nd5!
