Mickey Arthur believes Pakistan were denied a level playing field in their first Test against Australia, with the coach saying he was surprised former employers Cricket Australia (CA) opted for a pink-ball clash in Brisbane.
CA has made no secret of its desire to expand the day-night Test revolution since Adelaide Oval hosted the inaugural fixture last year.

Pakistan on the ropes after Aussie declaration
Steve Smith and Usman Khawaja both hit 50s before Australia's declaration left Pakistan's batsmen with an impossible task.
It scheduled pink-ball Tests in Adelaide and Brisbane this summer, with some past players and pundits questioning at the time if the Gabba was a suitable venue for the innovation.
The main concern raised by Ryan Harris and others was the prospect of the ball swinging around corners in the night session, creating an unfair balance between bat and ball and ensuring not all sessions were equal.
Steve Smith and Peter Handscomb negotiated Thursday's night session without losing a wicket, although both batsmen were far from comfortable facing the second new ball.
Pakistan didn't fare as well in Friday's night session, suffering a woeful collapse of 7-24 that led to Australia ultimately taking a first-innings lead of 287.
"I think there are (still problems with day-night Tests)," Pakistan coach Arthur told ABC radio.
"It's not an even playing field.
"You walk out at 1pm in glorious conditions like this; it's a totally different ball game to opening at 6pm.
"So there are still issues around it, I think, definitely.
"I was surprised that they had it at the Gabba. I thought that was the one place where conditions might be extreme. In Adelaide, it seems to be good, although the ball still goes around."
Arthur, who was sacked by CA on the eve of the 2013 Ashes tour, conceded the concept was "the future".
Pakistan took part in the only day-night Test to be hosted outside Australia, in which they defeated the West Indies earlier this year.
"Funnily enough in Dubai, it (the pink ball) didn't do anything," he said.
It appears likely CA will opt for at least one day-night Test in future home series. Adelaide Oval has been locked in to host an Ashes day-night Test next year.
CA chief James Sutherland suggested earlier this week he'd like to see more day-night Tests at the Gabba in future seasons.
Thursday's action was watched by a crowd of 26,343 - a record day-one crowd for a non-Ashes Test in Brisbane.
