                                       by Yury V. Bukayev

Dear readers, let me remind you that these my new posts about White's advantage and wins in such chess games are dedicated to the 150th anniversary of Alonzo Wheeler Jerome's publications with 4.Bxf7+ in Giuoco Piano. Now the world chess history knows a lot of cases, where White got an advantage or won here against grandmasters and other extremely strong defenders!

We should start this new part from the game

NN - Top GM Hikaru Nakamura (Kgn1111 - GMHikaruONTwitch, 3 min blitz, Chess.com, 2021)

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Qf6 8.Rf1 Nh6 9.Nc3 c6 10.d3 d6 11.fxe5 Qxe5 12.Qh4 Bb4 13.Bd2 Kd7 14.O-O-O Kc7 15.Bf4 Qe6 16.d4 Bd7 17.d5 Qg6 18.dxc6 bxc6 19.Qe7 Rae8 20.Qh4 Ng4 21.Qg3 Ne5 22.Bxe5 Rxe5 23.Qd3 Ra5 24.a3 Qg5+ 25.Kb1 Bxa3 26.bxa3 Rb8+ 27.Ka2 Rxa3+ 28.Kxa3 Qc5+ (White resigned), 

where White had several chances to get an even game or an advantage before his 18th move. And White's best chance was after 18.dxc6!, when he got a won position, but blundered immediately instead of 19.a3! Bxc3 20.Rxd6!! with a win. This game shows that Mr. Nakamura wasn't ready to play the Schiller defence 7...Qf6, because the first of his large mistakes was his 11th move already.

Further, let's mention the game 

Alexey Pugach - GM Petar Arnaudov (ChessCoachUA - PArnaudov, 3 min blitz, lichess.org, 2017),

where after 4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qxe5 d6 8.Qg3 Nf6 9.d3 Qd7 10.Nc3 Qg4 11.Qxg4 Bxg4 12.h3 Be6 13.Be3 Bxe3 14.fxe3 Ke7 15.O-O Rhf8 16.Nb5 c6 17.Nd4 Nd7 18.a4 Rxf1+ 19.Rxf1 Rf8 20.Rxf8 Nxf8 21.Kf2 g6 22.Nf3 Nd7 23.b3 a5 24.Ke2 Nc5 25.e5 dxe5 26.Nxe5 Kd6 27.d4 Nd7 28.Nd3 Bf5 29.g4 Bxd3+ 30.Kxd3 b5 31.axb5 cxb5 32.e4 a4 33.bxa4 bxa4 34.h4 a3 35.Kc3 Nb6 36.Kb3 Nc4 37.c3 Nd2+ 38.Kxa3 Nxe4 39.c4 Black lost on time. The final position is enough respectable for White for his very long play with a sacrificed material down and without Queens. I think, Black wasn't ready to meet Jerome gambit and spent too much time for his moves. White (like Black) could play much stronger in several cases - in opening and in endgame, so Black's task could become much heavier there and could take more his time. One of methods of how to win a blitz game with Jerome gambit is to play faster than your opponent without your punished blunders.
