Richard,
Thanks for the historical reference – it would be great if there were some sketches of these lost holes.
The example you quote from Hutchkinson clearly refers to the main shot for the" bolder" players as being the “direct route” over the bunkers, and the “shirkers” playing to the left of the bunkers as an alternative strategy. I wouldn’t interpret this description as cutting off the corner of a Dog Leg.
I agree with you that many of the ancient holes were played “off line” to avoid difficulties or create better angles - that is the joy of the choice of strategy which is available with a “Straight Hole”. The direct line, or even an alternative angle up the opposite side of the fairway, is still available, with no significant loss of distance.
My premise as described in the previous threads is a “True” Dog Leg is a forced angle of more than 22.5 degrees on the second shot after a full drive to the standard turning point.
Up to now the only “True” Dog Legs in Ancient Golf I have noted are the 7th at the Old Course and the 1st at Machrihanish (1879).
However I’m sure there are more if one looks around.
In any event the "True" Dog Leg in Ancient Golf was a rarity, as opposed to the modern era where they tend to be overused in my opinion.
