Ireland recovered from an early scare to beat Scotland 40-13 on Saturday and remain in the hunt for their first Six Nations title in 20 years.
Ireland, who beat Italy last week, turned on the style in the second half after their forwards had taken control of the match midwaythrough the first.
The victory, achieved without injured centres Brian O'Driscoll and Gordon D'Arcy, was richly deserved and puts Eddie O'Sullivan's team in great heart for the home games against England and France to come as they seek their second grand slam.
Scotland, so unlucky to lose to France last week, started full of running and a Hugo Southwell try and a Chris Paterson penalty gave them a deserved 8-0 lead.
Ireland recovered well, however, and hit back with tries for locks Malcolm O'Kelly, in his Irish record 70th appearance, and Paul O'Connell, and the boot of first five-eighths Ronan O'Gara to reach halftime 18-8 ahead.
Ireland went further clear early in the second half with a try for winger Denis Hickie, though flanker Jon Petrie hit back with a Scottish try after a rare spell of pressure.
The visitors soon regained control, however as prop John Hayes scored just his second try in his 51st appearance and replacement back Gavin Duffy got his first just minutes after coming on for his debut.
"It was tough to begin with and we really had to stick to our guns," O'Kelly told the BBC.
"We went out to play a really simple game, but we showed a bit of flair at the end. We are delighted and can go on with a bit of confidence."
Scotland, who lost every game last year, next host Italy, who were beaten 38-8 by Wales in Rome earlier on Saturday.
