For GB, playing its sixth game in nine days, this felt like a challenge too far. Despite another brave goaltending performance, this time from understudy Jackson Whistle, the Czechs dominated much of the play and finished with 46 shots on goal against 19 from the Brits.
Two years ago, GB stunned the hockey world by coming from 3-0 down to beat France 4-3 in overtime to secure their status in the world’s elite.
Liam Kirk’s fifth goal of the tournament put GB ahead against Sweden, who are ranked fourth in the world before the Swedes came back strong, firing 56 shots on the goal of Ben Bowns in a 4-1 victory.
Liam Kirk scored his fifth goal of the World Championship to go one clear at the top of the goalscoring charts – and Matthew Myers was named captain for the game on the special occasion of his 100th GB cap.
Myers will also captain his country on the very special occasion as he becomes only the fourth player in history to reach the milestone after Ashely Tait (110), David Longstaff (101) and Jonathan Phillips (101), who reached a century of caps against Denmark.
Liam Kirk scored twice to take his tally to the tournament to four, while Ben Davies and Mike Hammond were also on target on another famous night for British ice hockey.
After defeats by Russia and Slovakia in Group A of the Olympic Sports Centre in Riga, GB produced another superb performance against Denmark who are ranked 12th in the world.
Ben O’Connor scored his 18th international goal and Mike Hammond was also on target, scoring late to take the game to the extra period
