===3...Qf6 4.Nc4===
4.Nc4 has the advantage of allowing White to open the {{chessgloss|centre}} with d3, for example 4...fxe4 5.Nc3 Qg6?! 6.d3 exd3? 7.Bxd3 Qxg2? and now White is winning after 8.Qh5+ Kd8 (or 8...g6 9.Qe5+ and 10.Be4) 9.Be4. If 6... Bb4, however, White must be careful following the same line, e.g. 7.Bd2 exd3 8.Bxd3 Qxg2 9.Qh5+ Kd8 10.Be4 Nf6! because now if White plays Bg5, which would be necessary to win the queen in the earlier line, then ...Bxc3+ wins for Black. The main line continues 5...Qf7 6.Ne3! Black usually responds with 6...c6!?, when White can either accept the [[pawn (chess)|pawn]] [[sacrifice (chess)|sacrifice]] with 7.Nxe4 d5 8.Ng5 Qf6 9.Nf3, or decline it with the more popular 7.d3 exd3 8.Bxd3 d5 9.0-0.<ref>Kosten 2001, pp. 78-79, 83-84.</ref> The latter variation has been deeply analysed; the British [[Grandmaster (chess)|grandmaster]] [[Anthony Kosten]] analyses one line to move 32.<ref>Kosten 2001, p. 96.</ref> One line discussed by IM [[Jeremy Silman]] is 9...Bc5 10.Na4 Bd6 11.c4 d4 12.Nc2 c5 13.b4 Ne7 14.Nxc5 Bxc5 15.bxc5 Nbc6 16.Bb2 0–0 17.Nxd4 Nxd4 18.Bxd4 Bf5 19.Bxf5 Nxf5 20.Be3 Qxc4 21.Qb3 Nxe3!? 22.fxe3 Rxf1+ 23.Rxf1 Qxb3 24.axb3 Rc8 25.Rf5 and now 25...Rd8 or 25...Rc6 gives Black an excellent chance to [[Draw (chess)|draw]] the pawn-down [[Chess endgame|endgame]].<ref>Jeremy Silman, [http://www.jeremysilman.com/chess_opng_anlys/040801_two_wild_black_systems.html Two Wild Black Systems].

Ne7 12.Nexd5 cxd5 13.Nb5 is close to winning for White, and that the "old, discredited" 9...Bd6 (rather than 9...Bc5) might be Black's best try, though still insufficient for {{chessgloss|equalise|equality}}.<ref>[http://www.jeremysilman.com/chess_opng_anlys/040223_more_splat_the_lat.html More Splat the Lat].
