Answer: SYSTEM COVERAGE
In a system of 2,3,6 you can not do coverage. Besides, it seems that you have already won something and you can win even more. You can not get coverage in this system but you could also get coverage why? In order not to earn more? No, you leave it as it is to follow its path. Then if you do it out, it will mean that you do NOT believe in what you initially supported-played, so with the offer that the book makes to you for the out, it has already crumpled it. psychology and you are on burning coals. The book is afraid that you will beat him, so he gives you "in return" to save what he can and you will say yes? And of course not. Do not respond to the fear of his with yours. I am not an "expert", I told you my humble opinion and nothing more.
Of course, if the profit was a goose, for example, and more, I could tell you something else, but from what I see, I clearly say no.
The cash out is required, for example, if you have played a match only with a mountain odds, for example 8,00 to 30 euros and you go for 240 euros, and at 80 you win it and it gives you 220 euros to leave, yes there you take it and leave, because there is a risk of eating a goal and losing it all. In no other case.
Welcome to the forum and if you want the next time you will write something written in lowercase (small) letters because the chapters on the internet are like "shouting".
WELCOME !!!
