The King's Gambit
1 P-K4
P-K4

3 Kt-KB3 ...
To hinder the Check of the Black Queen.
3 ... P-KKt4
To hold fast to the Pawn plus.

5 Kt-K5
P-Q4
Black having many Pawns at stake must strive for rapid development so as to be able to strike hard blows with his pieces.
6 P-Q4 ...
White also must get quick action.
6 ... Kt-KB3
7 BxP
KtxP
8 Kt-Q2
B-K3
Hereby Black guards the weak Pawn KB2 and fortifies himself.
White may regain the Pawn, but only at the expense of giving up his advance in development.

A difficult Ending rather favourable for Black.
This interesting line of play, initiated by White's fifth move, was first analysed by Kieseritzky, a Polish master, and bears his name.
Another defence to it runs as follows:
5 ... B-Kt2
6 P-Q4
Kt-KB3
7 B-B4
P-Q4
8 PxP
Kt-R4
Here the Knight stands safe and menacing. Black wants to Castle soon.
9 Kt-QB3

10 Kt-K2 ...
To neutralize the Knight on R4. If 10 KtxKtP
Kt-Kt6; the King's file is opened to the advantage of Black.
11 R-R2
Q-K2ch.;
12 Kt-K5
BxKt; soon to be followed by R-K1.
10 ... P-QB4
In order to open up the centre.
If now 11 PxP in passing,
11 ... KtxP; Black gets quick development. After 11 QKtxP
KtxKt;
12 BxKt
PxP; the X loses its support
13 QxQP
Kt-B3;
14 KtxKt
PxKt.
11 P-B3

12 PxP
Kt-Q2
(This line of play originated in a game - Steinitz against Zukertort, Vienna tournament, 1882.) Black is well developed.
Instead of the Kieseritzky Gambit, White may choose the bolder line of the Allgaier Gambit.
