Having thought about it more I now think that Agincourt could well be correct. The answers can be a phrase, place or thing so Agincourt fits within those parameters, and as Roy Walker used to say on Catchphrase, if you say what you see A G in COURT you do get Agincourt. The 'Up to a point' answer must be right. The dingbat is UP UP. - which gives you up to (two) a point. I do accept though that 'Right up to a point' also fits as the right hand UP is next to the full point.
