Watson and Deep Blue, for two

IBMS

Think of a tech giant whose initials also stand for a famous AI chess opponent.

This clue refers to two famous IBM-developed AI systems: Watson, the supercomputer that won Jeopardy! in 2011, and Deep Blue, the chess-playing computer that defeated Garry Kasparov in 1997. The answer "IBMS" is a playful twist—it’s "IBM" with an extra "S" to hint at the plural "for two" in the clue. The abbreviation stands for International Business Machines, the company behind both groundbreaking projects.
