El Grande

Yes — in step 2 each player plays a Power card (starting with the start-player) and the highest Power card then takes the first turn in step 3 (you may not play a Power card value already played that round). (pp. 2–3)

No — the King's region is taboo: nothing (Caballeros, Grandes, or scoreboards) may be placed, moved, or removed there at any time. (p. 5)

During a general scoring (after rounds 3, 6, and 9) you first choose secret regions, then the Castillo is lifted and scored (1st=5, 2nd=3, 3rd=1), and afterwards each player moves their Caballeros from the Castillo to the single region they chose (players who chose the King's region return them to their Court). (pp. 6–7)

Tied players receive the points of the next-lowest position (e.g., two players tied for first each score second-place points), and player-count rules (2‑ or 3‑player games) can limit which positions score. (pp. 6–7)

You may choose whether to execute the special action before or after placing Caballeros, but you must complete each chosen step one at a time and you may not interleave them; some cards (e.g., certain Intrigue cards) explicitly allow partial execution and some special actions are optional. (pp. 3–4, 9)

If the Province lacks enough Caballeros you may take the remainder from regions on the board (but never from the Castillo), and you may also choose to take fewer than the Power card allows. (p. 3; p. 4)
