The problem for the Fork section has an incorrect solution. Gold can defend with rd6n, Ed5n, Re3w, Re2n. This protects both traps while also setting up a break of the pin on the camel through the new e3 rabbit and the d2 horse. The elephant can in fact capture the rabbit as described, but this requires 3 moves, which does not leave enough room to prevent gold's response: Hd2nn, Re3w, Hd4n, protecting the C3 trap again while also breaking the pin on the camel (technically silver CAN prevent this, but only by dropping the pin on the camel anyway). Silver can respond by capturing the new rabbit and blockading the northward direction, but then gold can send the other horse in for a sacrifice, buying time for his elephant to break the blockade.

After 2s: ed3n, Rc4w, ed4w, cb7s... 3g: Re3w, Re2n, rd6n, Ed5n 3s: ec4s, ec3n, Rd3wx, rc7s (setting up for a northward blockade) 4g: Hc2nn, Re3w, Hc4n (breaking the pin for a northward escape) 4s: ec4s, ec3n, Rd3wx, rd7w (completing the northward blockade) 5g: Hf3ww, Ed6n, rc6e (breaking the northward blockade while also protecting the C3 trap) 5s: ec4s, ec3n, Hd3wx, ??? (silver can't salvage his blockade. Best move is probably a tempo in the east) 6g: rc7w, Ed7w, Mc5n, ??? (probably a response tempo in the east)

Silver's elephant can pull the camel back of course, but it cannot re-establish the pin, so the camel will complete its escape next turn.

As best I can tell, there is no actual solution to the problem. Gold still loses rabbits and a horse with this response, which may not be worth it, but technically silver can't guarantee the camel.
