That's correct; trying out new strategies does not mean that the person should abandon the old strategy that he has been making use of, but rather they are just to try out new options that are out there, and even when they have known how that works, they could either combine the two together or be interchanging them based on the occasion that requires each of those strategies and the type of game they want to play at that point.
Sometimes I feel that knowing a lot is just that, knowing a lot, but to implement those things is Difficult, you have to have experience, therefore when we focus on seeing what the best strategy is , we will always say that what we apply is always the best , sometimes it is difficult to integrate the new 'because sometimes things tend to turn out wrong, and this is not only in the game, but also in the training, it is like that, sometimes knowing more is knowing more , but to implement it you have to have experience in how to do it.
