Nxg5 is a sound positional sac, but depending on the temperament of the player, it might not be the best move. The published annotation gives 12. Bxg5 Bxg5 13. O-O as +=, but white could play 13. h3 instead and white appears to have a simple positional squeeze. The critical line in the 12. Nxg5 variation turns out to be 12. Nxg5 Bxd1 13. Nxe6 Qb8 14. Nxg7 Kd8 15. Kxd1. Black's queen and rooks are temporarily out of play, black is up a pawn, but white has a protected passed pawn, and lots of pressure. (The annotator gave one line that ended "with the attack":). From DT-2's point of view, The Bxg5 line was gaining 0.20 pawn after each iteration, and so was the Nxg5 line. Except that the Bxg5 line has about a 0.20 pawn lead at the same depth. There appears to be no kill in the Nxg5 line when black king goes to d8 instead of the f file. Black would have to give up the extra pawn to activate the queen and the rooks, and while white is definitely better, black is not without counter play. On the deepest search that we checked out, black's evaluation stopped dropping at around -1.4 pawns, and black's pieces were becoming active." Nolot #3 doesn't have a concrete tactical solution like some of the other positions in the test.
