Q. A person who came to Mincha and after saying Hashem sefosai tiftoch and Baruch ata Hashem realized there are no asara mispallelim (minyan) present. May he say lamdeini chukecha and daven in a later minyan (where there will be asara), or do we say that once he started shemonessrei he may not stop, even though it won’t be tefilla btzibbur?
A. Horav Shlomo Miller’s Shlit’a opinion is that once he said the name of Hashem at the brocho he should continue with the rest of the amida, even if there is no mimyan. (He may daven a voluntary tefilas nedava later on with a minyan).
