In the previous post I suggested that White's last move, 10.Nc3, might not be best, as compared to the direct 10.fxe5, as it allows Black a move to prepare for the capture. Black cannot withdraw his Knight from e5, because of the threat Nd5+, forking King and Queen, but he can either counter-attack on White's Queen, or withdraw his King.
The following illustrative games (there are a lot, but they are worth playing over for a better understanding of the position) primarily feature two players well-known to the Jerome Gambit Gemeinde - MrJoker and Bill Wall - and a player who worked with a series of computers that I introduced years ago in "Jerome Gambit: Drilling Down (27)"
In 2006 I heard from Jeroen_61 of the Netherlands, who emailed me
Some time ago when Hiarcs 8 was released after receiving my copy I ran some small tournaments to see how things would go with Hiarcs. Other participants were Junior 7, Shredder Paderdorn (6.02) and Fritz 7. One of the tournaments I conducted with - the Jerome gambit as opening. They are games 40/40' + 40/40' + 40' (round robin two rounds, so 12 games in all). Only two were won by the white side....All were posted at a website that Jeroen_61 gave, although an attempt to use the url today got me the message De pagina is niet gevonden, which probably means just what it looks like.
Black uncovers an attack on White's Queen with 10...d6, and White's best is the counter-stroke 11.Nd5+, leading to the following: 11...Kd8 Best (11...Kf7 12.Qb3 (or 12.Qg3 Qd8 13.fxe5+ Ke6 14.Qg4+ Kxe5 15.d4+ Kxd4 16.Qd1+ Kxe4 17.Qf3+ Ke5 18.Bf4+ Ke6 19.O-O-O Kd7 20.Qg4+ Kc6 21.Qf3 Be6 22.Nf6+ Kb6 23.Nd5+ Bxd5 24.Qxd5 Ne7 25.Qb3+ Kc6 26.Qa4+ b5 27.Qe4+ Kb6 28.b4 Bxb4 29.Qxb4 Nd5 30.Qd4+ Kc6 31.Qxd5+ Kb6 Black resigned, MrJoker - AshNazg, Internet Chess Club, 2011) 12...Qh4+ (or 12...Qd8 13.fxe5+ Kg7 14.Nb6 Qh4+ 15.g3 Qxe4+ 16.Kd1 Bg4+ 17.Rf3 Bxf3+ 18.Qxf3 Qxf3+ 19.Ke1 Qf2+ 20.Kd1 Qf1 checkmate, MrJoker - goesoef, Internet Chess Club 2011) 13.g3 Qg4 14.fxe5+ Kg7 15.d3 dxe5 16.Nxc7 Rb8 17.Ne8 checkmate, Wall,B - Guest5541035, PlayChess.com, 2014) 12.Qg3 Best (or 12.Qc3 Qh4+ 13.g3 Qxh2 14.fxe5 Bg4 15.Qd3 Ne7 16.Nf4 Nc6 17.Ne6+ Bxe6 18.exd6 Ne5 19.Qe2 Qxg3+ White resigned, Fritz 8 - Hiarcs 9, The Jeroen Experience, 2003) 12...Nd3+ Best (or 12...Qe6 13.fxe5 dxe5 (or 13...Ne7 14.d4 Bxd4 15.Bg5 Re8 16.O-O-O Bxe5 17.Qh4 c6 18.Nxe7 Rxe7 19.Qxh7 Bd7 20.Rf8+ Be8 21.Rdf1 Kd7 22.Bxe7 Qxe7 23.R1f7 Bxf7 24.Rxf7 Re8 25.Qxg6 Kc7 26.Qe6 Kd8 27.Rxe7 Rxe7 28.Qg8+ Kc7 29.g3 Rg7 30.Qf8 a5 31.c3 a4 32.Kc2 a3 33.bxa3 Rh7 34.Qf2 c5 35.a4 Kc6 36.Qe2 Kc7 37.a5 Rh6 38.a4 Rh7 39.Kb3 Rh8 40.Kc4 Ra8 41.Qg4 Rxa5 42.Kb3 c4+ 43.Kb4 Ra6 44.h4 Rb6+ 45.Kxc4 Rc6+ 46.Kd5 Rxc3 47.h5 Rxg3 48.Qf5 Rd3+ 49.Ke6 Kc6 50.h6 Rd2 51.h7 Rh2 52.Qf7 b6 53.Qd7+ Kc5 54.Qb5+ Kd4 55.Qxb6+ Kxe4 56.Qb7+ Kd4 57.a5 Rh6+ 58.Kf5 Rf6+ 59.Kg5 Rf8 60.a6 Black resigned, mrjoker - igort, Internet Chess Club, 2010) 14.d4 Ne7 15.dxc5 Nxd5 16.Bg5+ Ke8 17.exd5 Qxd5 18.Rf2 Be6 19.Rd2 Qxc5 20.O-O-O Rf8 21.Qh4 h5 22.Bh6 Rf5 23.Rd8+ Rxd8 24.Rxd8+ Kf7 25.Rf8+ Qxf8 26.Bxf8 Kxf8 27.Qd8+ Kg7 28.Qxc7+ Kh6 29.h4 Rf1+ 30.Kd2 Rf2+ 31.Ke3 Rf5 32.Qd8 a6 33.Qh8 checkmate, Wall, B - Aburasian, Chess.com, 2010) 13.Qxd3 Best (or 13.cxd3 Qf7 14.Qg5+ White resigned, cliang - parrot, FICS, 2009) 13...Qg7 14.c3 Ne7 15.b4 Bb6 16.Nxb6 axb6 17.Qc2 Qh6 18.h3 Qh4+ 19.Rf2 Be6 20.d3 Rf8 21.a4 Qg3 22.Kf1 Qh2 23.Rf3 Qh1+ 24.Kf2 Bd7 25.b5 Be6 26.c4 Kd7 27.Qc3 Rg8 28.Bd2 Qh2 29.d4 Bf7 30.e5 Nf5 31.d5 Rge8 32.Re1 Nh4 33.e6+ Kc8 34.Rg3 Bxe6 35.dxe6 Rxa4 36.Qb3 Ra8 37.Qb2 Kb8 38.e7 Nf5 39.Rg5 d5 40.Rxf5 gxf5 41.cxd5 Ra4 42.Qe5 Ra2 43.Qd4 h5 44.d6 cxd6 45.Qxd6+ Ka8 46.Re6 Rc2 47.Qd8+ Rc8 48.Qxb6 Rg8 49.Rg6 Rxg6 50.Qxg6 h4 51.e8=Q Black resigned, Wall,B - BBchess engine, Lahore, 2015}

14.Bf4 Qe7 15.Bg5 Qg7
White has some positional pressure - on the dark squares, along the f-file - and an advantage in development, although not (yet) full compensation for his sacrificed piece. He can finally castle, then plan to double his Rooks.
16.0-0-0 Be6 17.Rf3 Black forfeited on time
Quite a surprise. As my opponent subsequently forfeited on time his game with the White pieces - and forfeited games to other players as well - something in the "outside world" must have intervened.
By the way, after the game, Stockfish 7 suggested that instead of doubling Rooks, I consider 17.d4!? Bxd4 18.Rxd4!? (eliminating the dark square Bishop) with the following possibility 18...Qxd4 19.Qf4 Qg7 20.Qxd6 Bc4 21.Rd1 when Black is still in a bind, although the computer still puts him ahead by only about 3/4 of a pawn. A deep idea, not anything I had considered.
