Finished this, having, like others, struggled with 18 ac - but resolved when we realised the extent of the clashes, after we had deduced the phrase.
Re earlier posts, don't think we find the crosswords any easier, although some posts on this site will always help. Agree generally with Staurologist's comments. As relative newcomers to these threads, we suspect the participants are mostly among the more "elite" successful solvers out of the 500 or so regular submissions. We do not include ourselves in that category, with a typical batting average of 50% submitted and correct each year - partly due to holidays, stupidity and failure to attempt number puzzles and Playfairs etc. As to the last of these, is there any way "in" to Playfairs or must one just rely on intuiting the keyword from the context/theme?
