Simon Zebo intercepts!
He hoofs downfield. A foot race. Zebo v Scotland's Tommy Seymour!
Seymour wins. Laidlaw boots out and a breathless first half is done.

Former Ireland captain at Murrayfield
Ireland have a lot of possession but we're quite slow in the ball we're generating, and it just doesn't look threatening.
Scotland just look like they are really comfortable defending - they are making really big hits everywhere.
Scotland 21-8 Ireland
Scotland are up to within 10 metres, hunting a fourth try and a bonus point before the half-time whistle...
Scotland 21-8 Ireland
Some mighty hits from Scotland - Josh Strauss flattening Iain Henderson like Captain Haddock bringing down a galloping giraffe.
Turnover ball! Ireland have been flummoxed by the speed of the hosts' rush defence.

If Scotland go in at half-time at this level or better, they will be absolutely delighted.
If Ireland get another three points or more it changes the conversation for both Vern Cotter and Joe Schmidt.
Scotland 21-8 Ireland
Conor Murray hops with delight as CJ Stander clamps down over the top of Finn Russell and the Scotland back row would need to get an eviction notice to get rid of him.
Ireland would love a score before the break. Thirteen points is a heavy handicap to carry into the second half.

At this stage in the game, absolutely go for the points by taking the penalty. This is a really important period for both teams before the end of the half.
Scotland 21-8 Ireland
Quote MessageI said before this game that neither team would be thinking about bonus points but that has to be in Scotland's minds now. That was such a cheap try for Ireland to concede. What is going on in that Ireland defence? Scotland are in dreamland.

Paddy Jackson
Paddy Jackson stems the bleeding for the visitors with a kick from dead centre and 35 metres or so.
Scotland 21-8 Ireland
Unsurprisingly Stuart Hogg is leading the metres made and clean breaks statistics (43 and 2 respectively)

Jon Salinger: Wow, don't think anyone predicted this score!! What a first half of rugby.
S.A Richardson: Scotland for the Grand Slam?
Dov Tate: When they first announced the introduction of bonus points, what odds would you have had on Scotland getting the first one..?
Scotland 21-5 Ireland
Flower of Scotland is ringing around Murrayfield, Proud Edward's army being told exactly where to go.
Paul O'Connell
Former Ireland captain at Murrayfield
Outstanding play! Very tricky - no lift, no jump. Very simple.
And you can see the Irish were ready to defend the front and back of the line-out but that was a great little play.
You'd never have thought Scotland would be one off the bonus point before half-time.

What is inside centre Alex Dunbar doing in the line-out? He leaps in front of Tadhg Furlong, who is predicting it is going to a designated jumper.
That is an unbelievable move from Scotland. Straight off the training ground.
Alex Dunbar (con. Laidlaw)
Straight off the training-ground and it translates perfectly from playbook to pitch.
Centre Alex Dunbar sneaks into a line-out five metres out from the Ireland line. While the green shirts are distracted by the Gray brothers in the middle of the line, Ross Ford picks out Dunbar at the front and he saunters in unopposed.
That sort of canny, clever play is the sort of thing that Scotland might miss when coach Vern Cotter departs.
Laidlaw faultless once more from the tee.
