Well yes Gian-Carlo, that variation did have a rather speculative look to it,
didn't it? Queens and Rooks left hanging all over the board! I don't think Rebel
Century itself would play that line? It gives itself with White about +2.95 or a
little higher after 1. ..Ng4xf2 (Century 2.0).
Assuming the first five plies would remain the same I took up the analysis also
after 1. ..Nxf2 2.Rxf2 hxg3 3.hxg3 Qe5 with default Century 2.0. I'll try 1.
..Qd5-e5 as well with Century 2.0
