Artemis- Chess

“No problem. I thought we’d go native. Russians arouse less
suspicion in Russia. I have passports and visas.”
“Good. What is our cover?”
“What about Stefan Bashkir and his Uncle Constantin?”
“Perfect. The chess prodigy and his chaperone.”
They had used this cover many times before on previous search
missions. Once a checkpoint official, himself a chess grandmaster, had
doubted their story, until Artemis beat him in six moves. Artemis’s
technique had since become known as the Bashkir Maneuver.
