Sheffield Steelers maintained their narrow advantage at the top of the Elite League table as all three title-chasing teams picked up victories.
The Steelers saw off Coventry Blaze 2-0 to remain one point clear of Braehead Clan, who beat Edinburgh Capitals 5-1, while Cardiff Devils' 5-4 triumph over Hull Stingrays sees them lie a further three points behind with a game in hand.
Cullen Eddy opened the scoring for the Steelers just 25 seconds in before fellow defenceman Ben O'Connor doubled that advantage and Josh Unice turned away all 24 shots he faced for his second straight shutout and fifth of the season.
Braehead had an easier evening and rode a strong night from special teams to ease past Edinburgh.
Stefan Meyer scored both powerplay and shorthanded goals for the Clan, who also cashed in on the man advantage through Scott Pitt and Matt Keith. Matt Haywood wrapped it up with an even-strength marker.
Chris Culligan scored twice and Joey Haddad, Carl Hudson and player-coach Andrew Lord were on target as Cardiff edged to victory over the Stingrays.
Chris Higgins scored the shootout winner to earn Nottingham Panthers a 3-2 win over Belfast Giants and in the final game of the evening Ryan Grimshaw's shootout goal saw Dundee Stars beat Fife Flyers 4-3.
