9a Favourite pub for Jock, tot of usquebaugh taken in yard (4)
H _ _ F
(heaf or hoof!)
2d Lord in the wars, wih quibble about, separate piece of armour (7)
P _ L _ RON
(I assume it is Paldron or poldron, an alternative spelling of pauldron (armour bit). There is an anagram/in the wars of "Lord") but nop or nap for uibble???
If it is paldron, 9a = H _ AF and if it is poldron, 9a = H _ OF
9a - neither, HOF means a yard and a 'tot' of usquebaugh is its first letter. 2d - To quibble can mean 'to PUN or evade the issue by punning'. 'About' here indicates containment rather than reversal.
