Alastair Cook and captain Joe Root both scored hundreds as England dominated the West Indies in the inaugural day/night Test on English soil at Edgbaston on Thursday.
England were 348 for three at stumps on the first day of what is just the fifth day/night Test worldwide.
Cook was 153 not out after more than six hours at the crease. Together with Root (136), he put on 248 for the third wicket. The past and present England skippers had come together with their side faltering at 39 for two after both debutant Mark Stoneman and Tom Westley had been dismissed for eight.
Dawid Malan, given a reprieve on two, was 28 not out at the close.
Root's 11th fifty in successive Tests was a new England record and just one shy of South Africa star AB de Villiers's mark of 12.
For Cook, already England's leading Test run-scorer and century-maker, this was his 31st hundred at this level.
The West Indies, Test cricket's dominant force in the 1970s and 1980s, have long struggled away from home.
During the past 20 years, excluding matches against Bangladesh and Zimbabwe, they have won just three out of 86 Tests outside the Caribbean.
They arrived in England without several star players, the legacy of a bitter dispute with West Indies administrators and the lure of the Caribbean Premier League Twenty20 tournament that is taking place at the same time as this series.
Yet they still had two early wickets under sunny blue skies that promised ideal batting conditions.
Left-hander Stoneman's first two scoring shots in Test cricket were fours off Kemar Roach.
But that was as good as it got for Stoneman, brought in after England dropped Keaton Jennings following a run of low scores during the preceding 3-1 home Test series victory against South Africa.
