 If you were playing in "locked" "Double or Four", the one who says "Double" or "Four" has the option of locking or opening the "Hokom".In case it's locked you can't use the Judged suit as a first card in any trick, you can only use them when you don't have the suit that the other player has played, or don't have any other suit to play as a first card in the trick.Otherwise, "if its Three or Gahwa" you can use any suit you want, even if it was the Judged suit.
