Sorry about all missunderstanings, its like "canceled" was forming it, if he think the text mean to stand when the true count was +7 or if it was after +7 = 8+ or more. this is how it was written
"surrender up to +7, then stand"
it has actually nothing to do with basic strategy as you guys was writing, it was more about when to switch from basic strategy because the count are to positive, if i should switch from it when its +7, or +8
