I think it’s not just the pitch. We’ve had worse pitches with red ball where teams scored over 200 in India. I feel the pink ball and twilight conditions just dont cut it for test cricket at international level. Not a big fan of day night tests. I think artificial light can never substitute daylight conditions with test match pitches. White ball cricket is a different story with flat batting tracks made for limited overs. And I just didn’t get a classic Test match feel for day night matches.
ICC needs to stop experimenting with pink balls and day night tests. I bet the red ball traditional Test will last 4 days in similar pitch conditions.
I think the ball has played a big factor and if they can't produce a good quality ball for this kind of cricket the only other option would be using a white ball and having a new ball after 40 overs. Or it's going to have vastly different tactics to other test matches. I could envisage cross seam deliveries being more useful than traditional seam or swing.
In terms of the twilight I think only 3 of the 30 wickets were lost in 3rd session (I dunno what time it gets dark over there).
Any match that doesn't last two (three, realistically) days needs to be looked at and lessons learned about why, because I certainly don't think this was down to batting technique. Of course if they want to introduce four day test matches then just use the pink ball.
If a pink ball is going to accelerate the speed of the game then a better pitch needs to be prepared.
