Widow's Watch and Ambush

By rwjohnson, in 2. AGoT Rules Discussion

Sorry if this has been asked before, but if you bring a card out using Ambush, can you kneel Widow's watch to search for a duplicate?

Ambush is still considered playing a card from your hand, is it not?

That's my understanding, but I wanted to check.

Ambush lets you "put a card into play", not "play" it.
