Depends what you mean by this, as the phrase "playing somebody onside" has absolutely no meaning in the laws of football.There's a lot of people that don't understand how a goalkeeper can play someone offside.
Nope, you would have to restart with a dropped ball then blow the half time whistle after the proper time has elapsed (except at the specific circumstances I am referring to).If it becomes burst in the air just as the first half whistle is about to be blown?
