The world's best player of Go (the world's most complicated board game) was roundly defeated by a Google program called AlphaGo in the first game of their three-game match this week, per the NYT.

Why it's so complicated: Go has an incalculable number of possible moves, meaning that a supercomputer can't simply crunch the numbers. Instead, AlphaGo uses artificial intelligence to learn new techniques each time it plays — even learning more by playing against itself. Because Go has been played for thousands of years, AlphaGo's unorthodox moves can ruffle grandmasters like Ke Jie, the world's best player.

What's next: Ke defeated AlphaGo last year, but said now that it's "improving too fast," calling it "a different player this year compared to last year." Google hopes to transfer AlphaGo's exponential learning success to other applications, like scientific research and medical diagnoses.

A federal judge ordered Oath Keepers leader Stewart Rhodes to remain jailed Wednesday until trial on charges stemming from the Capitol riot.

U.S. Magistrate Judge Kimberly Priest Johnson e in the t figure charged in the Jan. 6, 2021, insurrection had access to weapons and his alleged "continued advocacy for violence against the federal government" gave credence to prosecutors' view that, if released, Rhodes could endanger others.

GOP to use Supreme Court fight to target vulnerable Dems

Conservatives know they're unlikely to stop President Biden from filling a Supreme Court vacancy, but they plan to target Senate Democrats who face competitive re-election fights and are all but certain to vote for the successor to Justice Stephen Breyer.

Between the lines: The general strategy will be to tie those Democrats to positions seen as political liabilities in states like Arizona, Georgia and New Hampshire, where incumbents are seeking re-election this year, an operative briefed on early strategy talks told Axios.

U.S. and NATO answer Putin in writing while bracing for Ukraine invasion

The U.S. and NATO provided Russia with written proposals on Wednesday to advance a "diplomatic path forward," even as they warned that Russia could invade Ukraine within days.

Why it matters: This is a delicate diplomatic balancing act. The U.S. and NATO want to show they're serious about diplomacy but unwilling to compromise on "core principles" — all without providing Vladimir Putin with an additional pretext for escalation.
