Triggering Chalice of the Void

[seamonkeyman]

How does Chalice of the Void work with the new trigger rules? It doesn't say MAY on the card, but I'm not sure if that even matters anymore with the update trigger policy.
If I were to cast a spell that should be countered (say a Brainstorm vs. Chalice on 1), does my opponent have the acknowledge the trigger for it to occur? Could they decide to let the spell through if they desired?
Thanks for any replies.

They have to demonstrate awareness of the trigger before it would actually impact the game. We recently had a case with Carsten Kotter playing Ponder into a Chalice@1 and his opponent just sitting there, saying nothing. Only when Carsten tried to resolve the Ponder, his opponent suddenly remembered the interaction and had the Ponder countered.

Your opponent can however not knowingly "forget" a mandatory trigger like Chalice, Dark Confidant etc. Doing so would be Cheating.

Like constantly using City of Traitors as super Sol Ring? Have fun judging "knowingly" ... seems like if you are a name grinder you can do it constantly.

I'm not clear who you're referring to when you say "opponent," (it's not clear who controls the Chalice in the OP either) but you can only get in trouble (read: a warning, escalating from there) if you forget your own trigger and the trigger would be detrimental for you.

From the IPG (http://www.wizards.com/ContentResources/Wizards/WPN/Main/Documents/Magic_The_Gathering_Infraction_Procedure_Guide_PDF2.pdf):

The controller of a missed triggered ability receives a Warning only if the triggered ability is usually considered detrimental for the controlling player.

So let's say we have two players, player A and player N, and player A controls Chalice on X=1.

-If player N casts a 1CMC spell and player A doesn't acknowledge Chalice, that's ok.
-If player A casts a 1CMC spell and doesn't acknowledge their own Chalice trigger, that is probably cheating. (Assuming they're aware of it--which, obviously, they should be.)

Absolutely. If your opponent has Chalice in the game, you can still try to play a spell. If your opponent does not say: "Hey, I have a trigger here!", you can resolve the spell.
