No Fun Against the Pawns

Philidor1792 recently shared the following game, where his quest to play a sort of reversed Jerome Gambit led him to a situation where he faced a piece sacrifice and he had to deal with the onslaught of some very uncomfortable "Jerome-like pawns". It took a while to win this one.

1.e4 e5 2.Nf3 Bc5 

An old line, going back at least as far as Salvio's analysis in Il Puttino, altramente detto, il Cavaliero Errante, del Salvio, sopra el gioco de Scacchi, (1604), it is currently referred to as the Busch-Gass Gambit ( See "Worth A Second Look" Part 1, Part 2, and Part 3; as well as "Busch-Gass Gambit").

3.Nxe5 Nc6 

Chiodini's Gambit. Chessville.com had a good article by Clyde Nakamura on the line. (Chessville is no longer functioning, but I was able to use the WayBackMachine to recover the article; the link should be good.)

4.Nxf7 

Interestingly, Nakamura in his article on Chiodini's Gambit quotes analysis by Stefano Vezzani, an email friend of his, which gives this move a "??" and refers to it as "a common mistake". 

4...Qf6 

A light-hearted alternative: 4...Qh4 5.Bc4 Qxf2 checkmate, Nguyen Bao Do - Dich Tai Khuu, VIE-ch, U07, 2014.

5...Qxf7 6.c3 

Here we have reached the end of Vezzani's analysis of the sub-variation, a position he evaluates as a winning advantage for Black ("-+").

Houdini 3 considers it simply advantageous for Black (by about a pawn).

As we will see - and as many have seen while facing "Jerome pawns", things are still not easy.

6...Nf6

From a strategic point of view, Houdini suggests retreating the Bishop to the Kingside with 6...Be7. 

7.d4 Bb6 8.g3 0-0 9.Bg2 d5 10.e5 Ne8 

Instead, Houdini suggests the cold-blooded madness of 10...Nxe5!? 11.dxe5 Ng4 12.f4 Bf2+ 13.Kf1 Bb6 14.Na3 Bf5 but I am not sure how appealing that is to human players.

With patience, Black has captured a couple of pawns.
