"Choose" effects with Thoughtseize

[JustPAT4]

Thoughtseize instructs the caster, "you choose a nonland card" from the targeted players hand. It doesn't say "you may choose."

Does this mean that the caster must choose a card from the targeted player's hand if there is a legal choice? Further, if Thoughtseize gets hit by Misdirection targeting the caster instead, must the caster then choose a card from his/her own hand if there is a legal choice?

Sorry if this is obvious--I just want to be clear. Thanks.

Yes, and yes.

A key with Misdirection and Thoughtsieze is that it says reveal and not look at - if an effect requires you to choose a card in a non-revealed hidden zone and has a restriction (like "nonland"), you don't have to choose anything.

Then again, I don't think they print discard spells with "look at" anymore.
