The below are the openings discussed in the next portions:
In the Zhuraviev CounterGambit, black counters white’s attack with the queen by sacrificing the pawn for a lead in development. White is not able to castle on the king side and if white wants to castle on the queen side , it takes a lot of time as the position is such that the queen is placed on d2 when the rook develops with a tempo on g6 square. There is also a pressure on the c3 knight as d3 has to be played at the right moment allowing d5 as the knight will then be pinned. The games proceed with black trying not to exchange as many pieces as possible inorder to reduce the chance of a losing a game.
The below game shows how to proceed further in the game after the pawn is sacrificed:
1.e4 e5 2.Nc3 Bb4 3.Qg4 Nf6 4.Qxg7 Rg8 5.Qh6 Nc6 6.d3 Rg6 7.Qd2 d5 8.exd5 Nxd5 9.Nge2 Be6 10.a3 Be7 11.b3 Qd7 12.Bb2 0-0-0 13.h4 Nxc3 14.Nxc3 Nd4 15.Ne2 Bd5 16.Nxd4 exd4 17.0-0-0 Ra6 18.Qf4 Bxa3 19.Bxa3 Rxa3 20.Kb2
Black has got back the pawn with an added advantage
Qe7 21.Be2 Qxe2 22.Kxa3 Qxc2 23.Rb1 Rd6
A blunder by black!!
24.Qxd6 cxd6 25.Rbc1
Hamper-Mietner Opening has been played at a GrandMaster level quite frequently, white’s king rolls on the board and a precise play is required to be played by both black and white to stabilize the position. It is a double edged position and a player may sometimes give in to the huge pressure of his king being out in the open or black may give in to the pressure of his lost piece.
1.e4 e5 2.Nc3 Bc5 3.Na4 Bxf2+ 4.Kxf2 Qh4+ 5.Ke3 Qf4+ 6.Kd3 d5 7.Kc3 Qxe4 8.Kb3
A chance for white to improve his position by blockading the queen’s path towards the white king.
9.a3 Qxa4+ 10.Kxa4 Nc5+
A winning procedure would be getting the king into black’s camp further.But….
a5+ 12.Kxc5 Ne7 13.Bb5+ Kd8 14.Bc6
b6+ 15.Kb5 Nxc6 16.Kxc6 Bb7+ 17.Kb5 Ba6+ 18.Kc6 Bb7+ 19.Kb5 Ba6+ 20.Kc6 Bb7+ 21.Kb5
And a repetition!
This opening is similar to zhuraviev countergambit but with the bishop on the c5 square rather than on the b4 square. The difference is now the bishop on the c5 is pressuring the f2 square. In the giraffe attack unlike zhuraviev attack if the pawn on the g7 is taken then it’s already completely lost for white as after a few moves when the rook attacks the queen on h6, the queen cannot return to the e3 square because of the bishop and white queen is almost trapped.
So here, the best way to proceed would be not grabbing the g7 pawn and white might even try castling on the queenside and the game continues with early queen development.
1.e4 e5 2.Nc3 Bc5 3.Qg4 Qf6 4.Nf3 Ne7 5.Qg3 d6 6.Bc4 h6 7.Na4 Nd7 8.0-0 c6 9.Nxc5 Nxc5 10.Re1 Be6 11.Bf1 0-0-0 12.d4 exd4 13.Bf4 Qg6 14.Nxd4 Nxe4
This move might lead to dangerous position for black as white might in a few moves sacrifice the rook for two pieces with the black pawns in an unstable position.
15.Qxg6 Nxg6 16.Nxe6 fxe6 17.Rxe4 d5 18.Rb4 a5 19.Ra4 b5 20.Bd3 bxa4 21.Bxg6 Kd7 22.Be5 Rb8 23.Bxb8 Rxb8 24.b3 a3 25.f4 Kd6 26.Kf2 Rf8 27.Ke3 Rf6 28.Bd3 c5 29.g4 Rf8 30.h4 Rb8 31.c4 a4 32.bxa4 Rb4 33.Rb1 Rxa4 34.Rb6+ Kd7 35.cxd5 c4
And white is simply a piece and never lost an advantage after Nxe4.
In the Omaha Gambit, black does not develop his dark squared bishop and white tries to take advantage of it and expands on the kingside by moving his f pawn into the attack. Though it may seem that white seems to be dangerously expanding with the f pawn, the absence of bishop on the forward position helps white in implementing this idea.
