Firstly Len that's horrible mate hard lines. I'm a gambler of the truest nature really so I'd let 99% of things ride. But anyone who says they'd never cash out I find must be full of **** to some extent. Wasn't there a big one at Cheltenham last year where a bloke had some sort of miracle acca that ran for over a year and the lot was riding on was it Envoi Allen who was heavy odds on on the day ? Was it something like a half a millon cash out or something like that and literally nothing if it lost tbh I think most punters would have cashed out after the first couple of legs at Royal Ascot tbh but he stood it a long way. Then cashed out before the thing fell with a decent chunk left to ride on it. I can't imagine anyone alive who wasn't already worth a Million who would have let that ride....maybe Slim, maybe but then he's probably worth a Mill or two by now anyway.
L15's as luke pointed out if you've had 3 winners you've already got a good chunk back and whatever that chunk is you have an equal amount "running on "your last horse so they'll offer you normally a bit less than that. I'd always let them run no matter what. Those really are the days you live for as an everyday punter, I'd rather have a nearly story than a few extra quid and I have plenty of nearly stories. Other people are talking like traders and make fair points but its not my game I'm never going to get a bit of blood in it cashing out for small profits. The way I look at it Len is something I got told a long time ago and are the truest words spoken, you'll never win anything if you're afraid to lose.
