Ponziani Update #19
by David Taylor

I noticed a mistake in my analysis of Update #3. So this is a revision or at least new analysis having to do with the same game/line. 
The game is Halwick Jr - Morgado, W1998F.001 IECG email, 1998. 
The whole line for White with 8. c4!? is complicated with lots of candidate moves for each side. 
Hopefully the line will be "tested" in actual play.

1.e4 e5 2.Nf3 Nc6 3.c3 d5 4.Qa4 f6 5.Bb5 Nge7 6.exd5 Qxd5 7.0-0 e4 8.Ne1 This is the "book line". [ In my Ponziani Update #3, I suggested 8.Nd4 Bd7 9.Nxc6 Bxc6 10.Bxc6+ Nxc6 11.Re1 ; however after 8.Nd4 Bd7 9.Nxc6 I failed to notice Black can play 9...Nxc6! and then the best I can find for White is 10.Na3 with about even chances.; 
So this Update is now suggesting 8.c4!? Qd6 ( 8...Qe6 9.Re1 a6 10.Nc3 White advantage; 8...Qf5 9.Nd4 Qc5 10.Nb3 big White advantage; 8...Qd8 9.Bxc6+ bxc6 10.Ne1 leads to some White advantage; 8...Qc5 9.b4 Qd6 10.c5 leads to some White advantage) 9.c5!? Qxc5 10.d4 Qd6 ( 10...exd3 11.Bxd3 Be6 12.Re1 0-0-0 13.Nc3 Nd4 14.Be4 c6 15.Be3 Nef5 16.Nxd4 Nxd4 17.Rad1 White is winning; 10...Qf5 11.Nh4 Qe6 12.Nc3 Bd7 13.Re1 f5 14.Bg5 Qf7 15.d5 Nxd5 16.Nxd5 Qxd5 17.Rad1 Qf7 18.Nxf5 Qxf5 19.Rxe4+ wins; 10...Qh5 11.Re1 Bg4 12.d5 exf3 ( 12...Qxd5 13.Nc3 Qd7 14.Nxe4 Bxf3 15.gxf3 0-0-0 16.Be3 Qf5 17.Ng3 Qxf3 18.Red1 White is winning) 13.Bxc6+ bxc6 14.Qxc6+ Kf7 15.Qxa8 fxg2 16.Nc3 Ng6 17.Qe8+ Kg8 18.Be3 White advantage; 10...Qb6 11.Nfd2 Bd7 12.Nc4 Qxd4 13.Be3 Qd5 14.Nc3 Qe6 15.Nxe4 Nf5 16.Nc5 White advantage) 11.Nfd2 f5 ( 11...Bf5 12.Nc4 Qd7 13.Ne3 0-0-0 14.d5 Nxd5 15.Bxc6 bxc6 16.Qxa7 Qe6 17.Nxf5 Qxf5 18.Nc3 some White advantage) 12.Nc4 Qxd4 ( 12...Qe6 13.Nc3 Bd7 14.Rd1 Nd5 15.Nxd5 Qxd5 16.Ne3 Qd6 17.d5 Nb8 18.Nxf5 White is winning) 13.Bf4 Qd7 ( 13...Kf7 14.Nc3 Be6 15.Rad1 Qc5 16.Bxc7 Nd5 17.Nxd5 Bxd5 18.Nd6+ Bxd6 19.Rxd5 White is winning) 14.Rd1 Nd5 15.Ne5 Qd6 16.Nc3 White is winning] 8...Bf5 9.f3 exf3 10.Nxf3 Bd3! 11.Bxd3 Qxd3 12.Ne1?! [ Black won the game but White should have "bailed out" here with 12.Nd4 0-0-0 13.Ne6 with approximately an equal game]
