I agree with you, bobbycollins. I won't submit a puzzle if the solution isn't all my own work - well, with a bit of help from Chambers and Bradford's - and I only come here after I have completed them. I realise that there are others who use every crib that they can find but - with the recent Olympics in mind - just because one is aware that some others aren't playing clean, it doesn't mean one has to walk away from the competition.
Since I started to look seriously at The Listener earlier this year, I've managed to finish about three under my own steam and have sent them off; but the infrequency of my entries means that my chances of winning Brewer's Dictionary are probably vanishingly small!
