Q. Since Horav Shlomo Miller’s Shlit’a opinion is that the added section of “Baruch Hashem Leolam” before beginning the amida of maariv, has to be said complete or not at all, what happens if someone is davening and already started saying that bracha, but then the chazan rushed and he finished it while he was still in the middle of the bracha. Should he stop right there and begin the amida with everybody or finish the bracha and maybe lose tefilah betzibur? (see question 2158).
A. Horav Shlomo Miller’s Shlit’a opinion is that indeed, if someone realizes on the onset that he will not be able to recite the complete brocho of “Baruch Hashem Leolam” before beginning the amida of maariv, he should better avoid it. However, if he already started saying it, and then realizes he won’t be able to finish it on time to begin the amida together with the tzibur, he should skip and just say the end brocho of “Yiru Einenu”.
