Preparing the advance of the a-pawn is problematic, as the black queen stands in the way. Suddenly, Black instead activates his most passive piece, which seemed to have no particular prospects:

Shocked, White chooses the path of least resistance and loses quickly. It was essential to give the king some air with 24.Rcd1.
Incidentally, it is bad to play 24.Bxb5 axb5 25.Rcd1 Ra8 – Black’s attack develops of its own accord.
