2.Ne2 is the Keres Variation, a favourite of Paul Keres, and has similar ideas to the Chameleon System discussed under 2.Nc3 – White can follow up with 3.d4 with an Open Sicilian, 3.g3 with a Closed Sicilian, or 3.Nbc3, continuing to defer the choice between the two. 2.g3 is known as the Lasker–Dunne Attack.
