I do not know if this is best but 1. Rxf6+ seems to win. 1. -, Bxf6 2. Nd7+ 3. Nxf6 leaves black with a lost game. The try 1. -, Kxc5 even leads to mate. 2. Rd5+, Kxc4 3. Rc6+, Kb4 4. a3+, Ka4 5. Rc4# (or 2. -, Kb4 3. a3+, Ka4/Kc4 4. Ra6#/Rc6#).
1. Rf6:+! Bf6: 2.Nd7+ wins two pieces for a rook. And while white’s (remaining) pieces do not coordinate that well for the time beind, I do not see a way for black to exploit this.
1.Rxf6+ Bxf6
2. Nd7+
1. Rxf6 Kxc5
2. Rd5+ Kxc4
3. Rc6+ Kb4
4. a3+ Ka4
5.. Rc4++

Rf6+ Kc5 (Bf6 Nd7+) Rd5+ Kc4 Rc6+ Kb4 a3+ Ka4 Ra6#
Rx B and if KxB them ch ch mate
1. Rxf6 Kxc5
2 Rd5+ Kxc4
3 Rc6 +
RxN if BxR then N check and gets 2 light pieces for the rook. or if KxN then it will end in a mate in few after Re4+
International Chess Day is today!
1. Rf6:+! Bf6: 2.Nd7+ wins two pieces for a rook. And while white’s (remaining) pieces do not coordinate that well for the time beind, I do not see a way for black to exploit this.
1. R:f6+ B:f6
2. Nd7+ wins two pieces for a R (2… Kc5 is not possible) and hits the Re8.
There might be better by playing for a mating net. Black’s King is in a bad way out in no-man’s land.
R:f6 and then Nd7 taking the bishop??
1.Rxf6+! wins. If 1…Kxc5 black will get mated after e.g. 2.Rd5+ Kxc4 3.Rc6+ etc. Pretty!
Rxf6 looks good, but perhaps there is better.
