What is the function of the と in といきましょう

Question

「うふふ、そうですねぇ、せっかくですから直接対決といきましょう。士織さんもステージで何かやってくださいよぉ」

Hi. What is the function of the bold と? Is it short for と言って?

Thank you.

Answer 1

This と is "a quotation-like と" (I don't know the proper name) described in this question. と is not just for what someone said or thought; it can broadly mark the "content" of an action. The closest English equivalent would be "like ～", but in this case "go head-to-head" might be enough. This ～と行くか is a casual/colloquial expression used when someone has decided to "go for" something. It takes a (non-suru-verb, ordinary) noun.

• さあ、ラストスパートと行くか。
  Now, let's go for the last part.
• 次は日本酒と行きますか。
  Okay, let's try sake next.

Of course と行く can mean "to go with [someone]", too.

• 彼と行きたいです。
  I want to go (together) with him.
