Neat position. Thanks for sharing.
It seems like Black would be unable to connect back though I couldn't read through the semeai. Regardless, my thought is that Black A is not even forcing because White can capture the one stone or connect back. And if Black can secure the center, isn't Black ahead? Maybe better to just play safely. Trying to force at A is a bit greedy.
