Here, I have eyes only for d3. The 2 points are that it opens the line for the queen to f2 which is already attacked by the rook at f8, and, secondly, it forks the knight and queen, and the queen can’t easily leave the guard on f2. In this position, I can even possibly see black giving up the queen in some lines. Let’s look in detail:
The alternatives are worse: [3.Qc5? Rd1! 4.Qe3 Re1 5.Qe1 Rd8 will win a rook and a piece]; or [3.Rc1 Qe3 4.fe3 (or 4.Re3 Rd1-+) 4. …Nb4-+]. Continuing:
3. …..Rd8 4. Qc5 Rd1 5. Qe3 Bh6 6. Qh6 Re1 7. Kh2 c1(Q) 8. Qg6 Kf8 9. Qf6 Ke8 10.Qe6 Kd8 and black should find respite from the queen and have a decisive advantage.
Example [ Given this funny example to show some chess piece maneuvering , standard players handle either “d3” or consecutive moves differently but still Black can win this puzzle.] ======= 1… d3 2.R*d3 R*Rd3 3.Q*Rd3 Q*f2+ 4.Kh2 Rf3 5.Qe3 Q*Ng3+ 6.Kg1 R*Qe3 7.R*Re3 Qf4 8.Rf3 Qc1+ 9.Rf1 Q*Nc2 10.b3 Nd4 11.Rf2 Q*e4 12.a4 Qe3 13.b4 Ne2+ 14.Kf1 Ng3+ 15.Kg1 Qe1+ 16.Rf1 Q*Rf1+ 17.Kh2 Qf2 18.b5 e4 19.b*a b*a 20.c5 Be5 21.c6 Ne2+ 22.Kh1 Qg1++ Mate
I forgot to include this analysis the other day when I was putting my comment together from my notes, but 4. ….Nb4 isn’t a bad move for black, but it is no better than Nd4, just a different method of winning. From the top:
Though Opiniao didn’t continue his line, maybe he had the idea of continuing with Nc2, but this isn’t quite as good as it looks: [5. …..Nc2?! 6.Rf1! Qe3 7.Qc2! Rf4! 8.Qc1 Qc1 9.Rc1 Rf2! 10.Rb1 and black will have a hard time converting this into a win]. Continuing:
6. Qb4 Rf2! 7. Rg1 h4 8. Nh1 Re2 9. Qb7 Qd2 and the white knight still can’t be saved.
Picking between the two moves Nd4 and Nb4 at move 4 is probably a personal preference. I liked Nd4 more because it forces white to undouble black’s e-pawns and gives more scope to the bishop in the process, but the white knight still falls with proper play in both lines.
d3 will be the best move…

d3 wiil be the best move for black..

In this position, I can even possibly see black giving up the queen in some lines. Let’s look in detail:
1. …..d3
2. Rd3 Rd3!
3. Qd3 Qf2
4. Kh2 Nd4!
5. Nd4
Trying Rc1 is much worse: [5.Rc1 Nf3! 6.Kh1 Qg3 7.gf3 Qh3 8.Kg1 Qg3 9.Kh1 Rf3-+]. Continuing:
5. …..ed4 (Qe1 6.Ne6 h4 ok, too?)
6. Re2 Qf4
7. Qd2
Or if not, h4 wins the knight anyway. Continuing:
7. …..Be5 and how do you save the knight?
Back at move 2, white really has nothing better:
1. …..d3
2. Qe3 dc2 (Qc4 better, maybe?)
3. Rd8
The alternatives are worse: [3.Qc5? Rd1! 4.Qe3 Re1 5.Qe1 Rd8 will win a rook and a piece]; or [3.Rc1 Qe3 4.fe3 (or 4.Re3 Rd1-+) 4. …Nb4-+]. Continuing:
3. …..Rd8
4. Qc5 Rd1
5. Qe3 Bh6
6. Qh6 Re1
7. Kh2 c1(Q)
8. Qg6 Kf8
9. Qf6 Ke8
10.Qe6 Kd8 and black should find respite from the queen and have a decisive advantage.

d3 will win. White’s best response is to take the pawn but will lose the Queen
Dear Venky,
4….. Rf3
5Qxf3 Very funny!
Everyone says d3 but only Opiniao knows how to win it!
jqb,
I forgot to include this analysis the other day when I was putting my comment together from my notes, but 4. ….Nb4 isn’t a bad move for black, but it is no better than Nd4, just a different method of winning. From the top:

2. Rd3 Rd3
3. Qd3 Qf2
4. Kh2 Nb4
5. Qc3! Qc2!
Though Opiniao didn’t continue his line, maybe he had the idea of continuing with Nc2, but this isn’t quite as good as it looks: [5. …..Nc2?! 6.Rf1! Qe3 7.Qc2! Rf4! 8.Qc1 Qc1 9.Rc1 Rf2! 10.Rb1 and black will have a hard time converting this into a win]. Continuing:
6. Qb4 Rf2!
7. Rg1 h4
