This weekend, we go to Ukraine. FT columnist Gillian Tett introduces us to the tech entrepreneurs and engineers who have built strong links with Silicon Valley and western tech companies over the past few decades. These connections are helping them fight what she calls an ‘open source war’ against Russia. Then, data journalist Oliver Roeder invites us into the elite world of professional chess. Now that computers are magnitudes better than humans, the game has dramatically changed.
