1. Is there any rule obligating you to tell your opponent how many cards you have in hand? For the purposes of deciding whether to use Rule by Decree, or do an Intrigue challenge, for example.
2. In another game my opponent had Bronn and Jaime played, with Bronn's ability activated on Jaime. I launched a military attack and stealthed Bronn, with a claim of 1. My opponent knelt Jaime to defend but lost the challenge. He then wanted to play A Lannister pays his Debts to kneel Bronn so he could choose to pay the claim by killing Jaime, then save him with Bronn's effect.
Would this work? ALPHD can only be played after a challenge is lost, so wouldn't the kill effect of the claim already have happened?
Thanks in advance.
