If someone has to restart Shmoneh Esrei (because of Yale Yeyavo, Mashiva Haruach, Melech Hakadosh, etc) and is still in the middle of it, do you take 3 steps back, then forward, then back and forward again?
Or do you stay in your place and simply start again?
And when you start over, do you start from Baruch or from Hashem Sefasai?
