The midpoint of the championship brings three big fixtures: Wales v Ireland in Cardiff, England v Italy at Twickenham, and France v Scotland at the Stade de France for the Auld Alliance Trophy.
Round 3 of the Six Nations marks the championship's halfway point: with two matches played and three still to come, this is often the moment when the genuine title contenders separate themselves from the chasing pack. Sides who have picked up two opening wins position themselves as favourites; teams sitting at the bottom of the table must now play for their season.
The weekend of 20-21 February is a heavyweight slate: three matches across two days, including an Anglo-Italian classic at Twickenham, an explosive Celtic clash in Cardiff, and a French home tie against Scotland for the Auld Alliance Trophy, a symbol of the historic friendship between France and Scotland dating back to 1295.
The Principality Stadium, with its retractable roof closed, stages a Celtic classic. Ireland are likely to arrive looking to extend a winning run, but Welsh home support is legendary in Cardiff.
England host Italy in front of a home crowd. On paper a comfortable assignment for the Red Rose, but Italy have shown in recent seasons that they can put established sides under pressure.
Scotland travel to Paris for the Auld Alliance Trophy, which celebrates the centuries-old friendship between France and Scotland dating back to 1295.
In Cardiff, the Principality Stadium is one of rugby's great cathedrals. Its city-centre location, retractable roof โ closed for matchday acoustics โ and the singing of "Mae Hen Wlad Fy Nhadau" by 74,500 voices create a unique atmosphere. Ireland, on the back of a dominant recent era in the championship, will start as favourites, but Wales at home remain a dangerous opponent, capable of springing dramatic upsets.
The Red Rose host an Italy side still evolving. The challenge for England is to manage the fixture cleanly and avoid being dragged into a banana-skin afternoon. Italy in the last decade have learned to bring danger in the second half: this match can become tense if England fail to put it out of reach early.
The Auld Alliance was a diplomatic treaty signed in 1295 between the Kingdom of France and the Kingdom of Scotland in opposition to England, and is regarded as one of the oldest diplomatic alliances in the world. The trophy of the same name is awarded each year to the winner of France v Scotland in the Six Nations. For Scotland, a result in Paris would be a major championship statement.
