Stuck on the last two.
26d Tip cart up - ground for a fight (8) T?L???R?
36a King regularly compared to another piece (8) KN?G?T??
Must be knighted or knightly but I cannot see why!
Many thanks in advance
'tip cart up' is the subsidiary indication.
'tip' becomes 'tilt'
'cart' becomes 'dray'
'up' shows that the letters should be reversed in order.
'dray' reversed gives 'yard'
'tilt'+'yard'='tiltyard'
