Does white has good alternatives I see nothing after 19.Qg3 possible candidates before 19.Qg3 based on using Fritz on multi variation mode(all leading to advantage for black) 19.Qc1 19.Qd2 19.Nf6+ 18.Nh3 18.Bxd6 17.Rdd1 17.Rd2 17.Rd5 17.Rg3 17.Re3 17.Rdd1 seems the best candidate based on Fritz but still it seems that 17...Qf5 or 17...Nc4 gives advantage for black.
