The Hogeye Gambit

5/11/19 2 of 29

IntroductionThe Hogeye Gambit is a forcing way to get into an Italian Game, that is, a Giuoco Piano or Two Knights Defense. By playing a Center Game move order, we avoid not only offbeat defenses like the Latvian and Elephant Gambits, but more significantly we steer clear of the Symmetrical Petroff and the Closed Defense of the Giuoco. By encouraging black to play e5xd4 early, white has made black give up the center, thereby limiting black’s defensive possibilities.

1 e4 e5 2 d4 It’s a Center Game.

… exd4 3 nf3 No, it’s a Center Gambit!

… nc6 4 bc4 No, it’s a Scotch Gambit!

Which normally turns into a Giuoco Piano or Two Knights Defense, after

4 … bc5 or nf6

This monograph has three parts.

Part A covers the Scotch Gambit and early deviations.Part B covers the Two Knights.Part C covers the Giuoco Piano.

I have chosen the Modern Variation of the Two Knights and the Steinitz-Sveshnikov Variation of the Giuoco. These have similarities in themes and pawn structure. One could substitute other variations, e.g. offering the Max Lange Attack by 5 O-O in the Two Knights, or playing the positional IQP line or alternatively the wild Moller Attack in the Giuoco.

For more about Scotch and Italian Gambit systems, these two books are wonderful:• The Italian Gambit, by Jude Acers• Chess Openings for White Explained, by Lev Albert, Dzindzi, et. al.

Two Knights Modern Variation Overview1 e4 e5 2 nf3 nc6 3 bc4 nf6 4 d4 exd4 5 e5 ne4

ng4d5 6 bb5 ne4 7 nxd4 bc5

bd7

Black has two major choices. On move five he must decide what to do about the attacked knight. (See diagram above.) He can move it to e4 or g4, or he can counterattack with d7-d5. This last is most common and probably best. Later, on move seven, black can defend the knight on c6 by 7 ... bd7 or offer to sacrifice material with the “macho” 7 ... bc5.

Often white forces a “blob” pawn structure on black.

White strategies:1. blockade the blob2. attack on the kingside by advancing the e and f

pawns3. attack black’s a-pawn

White tactics:1. the e5-e6 shot2. f5-f6 to destroy black’s king position

Black strategies:1. hit white’s center e5-pawn with ... f7-f62. mobilize the blob, to trade off potential weaknesses

and/or gain space3. attack with pieces on the kingside
