The Wales coach, Warren Gatland, has expressed his anger over Scotland's unwillingness to take advantage of the Millennium Stadium's roof and criticised other teams for playing negative rugby.
The Scots play Wales in Cardiff on Saturday and said at the start of the week that they wanted the roof of the stadium to be kept open for the game, whatever the weather. With sleet forecast to arrive in the Welsh capital by Friday, Gatland believes an open house could lower the entertainment factor and dampen his team's attacking flair.
"Scotland have asked for the roof to be open and the weather is not expected to be that great," said Gatland. "You don't have to be a rocket scientist to know what to expect. The ball will be kicked in the air a lot. England got a lot of success doing that against us last week: Jonny Wilkinson only passed the ball five times.
"England tried to run early on against us but nothing came of it and they resorted to pick-and-go and box kicks. We can expect the same from Scotland: Dan Parks will put the ball up in the air or into the corners and, with Euan Murray, will make their scrum stronger than it was on Sunday against France. They will hope it is pissing down with rain.
"If it is dry and sunny and Scotland want the roof open, I could understand that but if it is rainy I do not see the point of having a roof and not using it. We are seeing a lot more positive rugby played with more sympathetic refereeing and we have a responsibility to the game, the public, media and sponsors.
"If it is raining you close the roof. We need some sanity. Why play in the wet when you don't have to? It is unusual that a team asks for the roof to be open this early in the week: they normally do not get around to it until the Thursday. Under the rules of the tournament, both sides have to agree for the roof to be closed and that is clearly not going to happen."
Under the Six Nations protocol, Wales can shut the roof whenever they want in the days leading up to the match but it will have to be open at least three hours before the 2pm kick-off on Saturday.
Scotland's coach, Andy Robinson, countered by saying: "The rules state that if we want to have the roof open then we can have that. I think it's an advantage to Wales playing with the roof closed because they're used to doing it in front of their home support. We're used to playing not under those conditions.
"We want the roof open. All the other games are played without a roof. This is the only place where you can have a roof. We are abiding by the rules, we've made the request, let's deal with it."
Gatland, meanwhile, sounded a bit like Arsène Wenger when he reviewed last Saturday's defeat against England at Twickenham, pointing out that Wales moved the ball while the opposition kicked it only to be undone by three tries which started from moves after Wales had lost possession in the England half.
"We have to be smart in our decision-making," he said. "You can't throw the ball around in the first minute in Test rugby. You have to be tactical and play it like chess. Games are tight in the first 30 minutes and it is about taking your chances in the second half. We want to move the ball and play some positive rugby but we must not be stupid and run up our own backsides when it is not on."
