It's one thing to play chess against a computer — you'll lose — but it's another entirely to play a collaborative word game. That stretches the limits of today's AI.

What's happening: Game geeks are trying to create bots that can play Codenames, the super-popular word guessing game.

  • It's played with two teams and a board with 25 words, like in the photo above.
  • Each turn, one person tries to come up with a single-word clue linking as many of the 25 words as possible; then, that person's teammates try to guess as many words as they can.

Giving a good clue is pretty easy for computers, using basic open-source machine learning tools for language understanding.

  • "I was surprised at how well it worked," said David Kirkby, an astrophysicist at UC Irvine who programmed a Codenames bot for fun. "It came up with clues which weren't obvious to me — but they made sense."
  • Kirkby's bot once gave the clue "Wrestlemania" to connect the words "undertaker" and "match."
  • Another bot coded by Jeremy Neiman, an engineer at Alphabet's Sidewalk Labs, used "telemedicine" to connect "ambulance," "hospital," "link" and "web."

What's really hard is guessing whether your teammates will understand your clue. This is something humans are great at — if you're playing with a sibling or friend, you can draw on shared experiences to come up with the perfect word.

  • The next big step is to create bots that develop an understanding of their teammates over the course of several games, says Adam Summerville, a professor at CalPoly Pomona who hosts Codenames AI competitions.
  • Achieving this goal is key to making robots that communicate better with people to accomplish a shared task.

U.K. sends patrol ships to British island amid fishing dispute with France

The United Kingdom's government announced Wednesday it has deployed two Royal Navy patrol vessels to the island of Jersey "as a precautionary measure," as tensions over fishing rights escalate with France.

Why it matters: British Prime Minister Boris Johnson said in a statement the government took the action to protect Jersey against threats of "a blockade" of French fishing boats at the island, which is off the coast of northwest France.

Social media's "in-kind contribution to Biden"

Facebook's continued suspension of Donald Trump's account extends the silencing of Joe Biden's most potent critic — and the current president's control over the national political narrative into his second 100 days.

Why it matters: Biden has been able to successfully focus on COVID-19 relief, his infrastructure plan and fielding his new administration, in part, because Trump hasn't been able to shake his social media muzzle and bray about the migration crisis or any White House misstep.

Liz Cheney's long game

Rep. Liz Cheney (R-Wyo.) is all but rolling out the red carpet for her own ouster as House GOP conference chair next week and her expected replacement with Trump defender Rep. Elise Stefanik (R-N.Y.).

Why it matters: Cheney’s political falling out with House Minority Leader Kevin McCarthy (R-Calif.) is the ultimate proxy war between Republicans who remain beholden to a former president who falsely claims the election was stolen from him, or breaking free from Donald Trump to refocus on traditional conservative values.
