Candidates tournament game captaintugwash - evert823 with Guard and Witch

captaintugwash

Thanks. Black is losing his bishop or witch. His bishop cannot retreat, otherwise Nxd7+ wins the queen as well as guard. If black tries Ge8 (probably the best option) then I was planning on Nxe6, forcing Bxe6 Qxe6 and white is up a pawn and witch. Considering I also have an immense bishop on b6, and will soon be castling safely, black's position is completely hopeless here.
