Can a screener hold his fists together under his chin, and elbows outward, as he sets a screen?

Can a screener hold his fists together at his sternum, and elbows outward, as he sets a screen?

Thanks!

If his elbow extend any further than shoulder width apart and he makes contact with the defender then it is an illegal screen.

Samething if legs a spread apart to far

Anything is legal until there's contact. elbows out, illegal, if contact. samething if legs spread apart too far. But, wait... how far is too far? Shoulder width? Wider?

It depends. If the screener impedes the progress of the defender with those outstretched arms, you could have a foul on the screener. However, even if the screener has the elbows out, the contact might be on the torso and not involve those elbows at all. In that case, you might have a charging foul on the offense. Read up on guarding and screening in the rule book and case book. It's not that simple.

when setting a screen arms must be close to body

You are oversimplifying screening. There is much more to it than that. If A1 sets a screen with his arms out, it isn't automatically a foul on A1. If there is contact, the foul might be on B1 depending on the nature of the contact and who initiated it. A1's arms may cause a foul if they inhibit the movement of B1. Read the rule book on contact, screening and hands and arms, legal and illegal use.
