After Kd1 Bd4 Nxd4 Movei says exd4 Nb5 c6 Nxd4 Qb6 Be3 Nxe3 Qxe3 Qxb2 with 0.03 pawns for black. 11 4 18488 28830016 e5d4 c3b5 c7c6 b5d4 d8b6 c1e3 g4e3 e2e3 b6b2 d4c2 c8g4 d3e2 g4e2 e3e2 b8d7 d5d6 Black has also other attack ideas like Qh4 or Bd7 if black choose a move like Na2 and not Nb5. I agree that after Rf1 Bxc3 bxc3 white has the advantage. Uri
