I have played El Grande once (with myself ) to learn the game. At one point I found myself in a situation when the number of caballero heads on my power card exceeded the amount that I could actually take home from the province. The rules say that I then should bring home caballeros from the board and put them in my court. Have I understood it correctly? Do I have to bring caballeros to my court at all or can I choose to ignore the heads on my power card and just play the card to triumf the other players?
