What are the "Valencian Cup" rules?

Question

That's the format that the second round of the Comunitat Valenciana Nations Cup will be played under in the final round - but what are the rules?

Answer 1

Basically, players tee off before switching and playing their partner's ball for the next shot (on par fours) and for the next 2 shots (on par fives), before selecting the best ball and completing the hole in alternate shot (foursome) format. On par threes the best tee shot is selected before completing the hole with alternate shots.
