I'm there.
And this is factually incorrect.
Last night South Africa bowled 12 overs on Day 1 with the new ball, from 8.45 pm to 9.30 pm. It was night-time.
On Day 2 they bowled 22 overs with the second new ball, taking wickets in the 6th, 9th and 10th when it was twilight but none at all in the last 12 overs - just like yesterday. They again finished at 9.30 pm.
I have studied pink ball Sheffield Shield cricket closely, and these Adelaide pink ball Tests resemble that more than other Test cricket.
And wickets fall to the new ball at twilight, not at night time.
I have to disagree with you boss - wicket fell to good bowling & catching, may be condition might be more conducive to bowling at twilight time; but that's not new in cricket - there are different periods of a day in a Day Test as well. My point was your thought process of "SAF has lost the Test, because they didn't declare 35 minutes early". In Day Test, first 40-45 minutes of a Day always helps the pacers, particularly with new ball - how many times, teams have declared over-night on 302/6 just to take the advantage of that 45 minutes?
And, just to prove your flawed logic, you are knit-picking - AUS's last 2 wickets went on 89'5 & 90'5 over. By your logic, yesterday, by 2nd over AUS should have been 2 down. And, during your window of "night", Starc survived probably by a millimeter ....... Wicket won't fell in twilight if you bowl/catch poor or the batsmen plays exceptionally well - but yes, it might be helpful to bowl under changing light. Yesterday, Azhar put NZ in & that must be a horrible decision, as NZ ended at 77/2 @ 3.6 -with a foot note that Raval was dropped of a sitter on 3rd ball of the match & then Sohail, Wahab, Imran bowled absolute rubbish - green, brown, dusty wicket or morning, afternoon, twilight won't have mattered much with that sort of bowling & catching.
Tactical declaration is part of the game - it's not D/N Test specific. Once Athers (Or Gooch) declared with Hick at 98* (SCG), so that his bowlers can have 30 minutes before tea (one more over, there would have been an early Tea); another time Imran declared himself on 97 or 98; for same reason against SRL. But, here we have to see at what extent - you are putting 99% emphasis on bowling with new ball in that 45 minutes & the Test match is decided; which is absolutely hilarious - be it Pink or Red ball game. Personally, I think the match is evenly poised still now as AUS will have to chase against Shamshi & Rabada on Day 4/5 here. If SAF restricts AUS under 100 lead & bat well against new ball; they will be in drivers seat going to Day 4 - obviously it'll be difficult for them to survive the hour post dinner with Starc & Josh fresh after 40 minutes rest in twilight. That's the game always had been - play out difficult time & cash on later.
You have put SAF out of the Test, because of 15 minutes delay in declaration (I am going by your facts - Hashcomb was out on 86'1 over - so, by your logic, had Faf Declared with 16 overs at hand, instead of 12, AUS would have been 3 down last light

), which I don't think - next 3 days are in weekends, we'll see almost every ball of the match.
