White is huge advantage in development, so there must be a combination.

Candidates move are :

a. Nf6+ (check)
b. Qxe6+ (check)
c. Rxd8+ (check)
d. Bxe6 (take material)
e. Nxh6 (take material)

If a. 1.Nf6+ Bxf6 is nothing for white

b. 1.Qxe6+ fxe6 is nothing for white

c. 1. Rxd8+ Kxd8 2. Nf6(intending to play Qe5 and Qd6) ..Ke7 3.Qe5 Rd8 4. Qc5+ Rd6 (the only move) 5. Ne4 (attacking rook) Qd4 6. Rxf7+ (forcing) ..Kd8 (if 6..Kxf7 then 7.Nxd6+ the black queen is loss; if 6..Ke8 the same 7.Nxd6+ winning) 7.Qxd6+ Qxd6 8. Nxd6 white is one knight ahead

d. 1.Bxe6 Bxe6 is nothing for white

e. 1. Nxh6 Qxe6 is nothing for white

1.Rxd8+.Kxd8.2.Nf6!.

>A-2......Qxf6.3.Rxf6 white is up a Q for N with a continuing mating attack.

>B-2.....Kc7.3.Qe5+.
>>B1-3....Kb6.4.Rb3#
>>B2.3....Kd8.4.Qd6+.Bd7.5.Qxd7#

>C-2.....Ke7.3.Qe5!.
>>C1-3....Rd1.4.Qc5+.Rd6.5.Ne4!.Qd4 otherwise black loses R to remain piece behind with raging attack..6.Rxf7+!.
>>>C11-6.......Kxf7.7.Nxd6+.Qxd6.8.Qxd6 and white has a Q for R with a easy win.
>>>C12-6......Kd8.7.Qxd6+.Qxd6.8.Nd6 and white remains a piece up while black has no counterplay; white will win easily.

Perhaps
1. Rd8 Kd8
2. Nf6
with the following Qe5 - Qd6. Cannot find satisfactory response for the Black

24. F6 G4 - Bad Black move, G4
--------------------------------
24. F6 B6 - Better Black move, B6
25. D2 E7
26. B4 C5 - Black is out of danger

The satisfactory response for the Black would be: 2. ... B6.
3. D2 E7
4. B4 C5 - Black is out of danger

I spot my error.
2. Nf6 B4
3. QE5 There is no defense for Black.

I salute Caruana for such a cool chess puzzle.
