I will be going over the move 3...g5. In which case, white's most popular move is h4. I didn't cover enough information on this well enough on my fourth post, so I'll try posting more information on this post. After h4, black will always play g4, dislodging the knight. White has 2 options for the knight: Ne5 or Ng5. Ne5 is the most popular and Ng5 is the best move, but least popular. So let's start with what happens after Ng5. After 5.Ng5, this opening is called the "King's Gambit Accepted: Allgaier Gambit". White will eventually sacrifice the knight to gain some compensation for the lost piece.
As usual, black will play 5...h6. This move is trapping the knight. White will play 6.Nxf7. Sacrificing a knight to gain an attacking initiative on the king side. This is called the "King's Gambit Accepted: Kieseritsky, Cotter Gambit".
Black always captures the knight. 6...Kxf7. Now white has 4 options: 7.d4, 7.Nc3, 7.Bc4+, or 7.Qxg4. According to the engine, Bc4+ is the best move. The most popular move played is d4, which is the worst move out of the 4. I'll go over d4, since this is ironically the worst most popular move. After 7.d4, this opening will be called the "King's Gambit Accepted: Allgaier, Thorold Attack".
7.d4 is just completing their long term goals of controlling the center, also d4 is aiming to push the e pawn towards black's king. Black's best move is Nf6, which was only played in 1 game and black won it. Black's most popular move is d5. Black wants to develop their light-squared bishop, also black wants to attack at white's center. White will play 8.Bxf4. Simply winning a pawn. Again, black's best move is 8...Nf6, simply developing the knight also putting more pressure on the e4. 8...dxe4 is a line, but after black takes the pawn, white will check the enemy king with their bishop. 9.Bc4+ Black's king will go to g7. After 9...Kg7, white will check the enemy king again with Be5+. This is called the "King's Gambit Accepted: Allgaier, Thorold, Cook Variation".
10...Nf6 is black's only move if they want to stay in the game. Any other king move will just lead to white having an advantage. White will 11.O-O. This move puts more pressure on the knight on f6, also puts the king to safety. Black will defend the knight with 11...Be7. Afterwards, the position will test which player can defend properly and which player has a good attack.
This is what happens after white plays d4. Lets take a look at 7.Nc3. After 7.Nc3, this opening is called the "King's Gambit Accepted: Allgaier, Blackburne Gambit".
This move is just continuing with their development. This move can also transpose to the Vienna Game, after black plays 7...Nc6. That is a different topic though. Besides, 7.Nc3 isn't a great move according to the engine. Black can play Nf6, which is the best move recommended by the engine. This move is developing and piece and bringing the piece into the defense. Play will follow from there.
Lets look at 7.Qxg4. 7.Qxg4 is simply winning a pawn and putting black's king close to danger. 7...Nf6 should be played by black. Getting their pieces into the defense. There is only 1 game played in this line so I'll share this to you. After 7...Nf6, white will play 8.Qxf4. Winning another pawn and threatening to win back the knight. Black will play 8...Bd6. This opening has a disturbing name and idk if I'll get my post dropped for mentioning the name, but I'll risk it: "King's Gambit Accepted: Allgaier, Horny Defense".
I don't know who gave this opening this certain name, but I condemn them. 8...Bd6 is simply attacking the queen. Note that you can't defend it with the e pawn, because black will capture the pawn with their bishop. You can never take the bishop since your queen is on the same file as the king and pins are possible.
White's best option after 6...Kxf7 is 7.Bc4+. This opening is called the "King's Gambit Accepted: Allgaier, Urosov Attack".
It is the best move recommended by the engine. You are checking the enemy king. Any king move from black will allow white to have a better position. Give back a pawn with 7...d5. After 8.Bxd5, you move the king to e8 8...Ke8. That is his safest square on the board.
This is all of the decisions that can be made after white plays 5.Ng5. Now we will be going over 5.Ne5. This opening is called the "King's Gambit Accepted: Kieseritzky Gambit".
In this line, there are a lot of options that can be played by black. I will be doing the 3 most popular options: 5...Nf6,5...d6, and 5...h5. The rest will be sideline options for black.
We will start with h5 first. After 5...h5, this opening is called the "King's Gambit Accepted: Kieseritzky, Long Whip Defense".
h5 intends to protect the g4 pawn from white's knight on e5. Although, this does defend the pawn, white has a better position. White's next move will cause black to be a bit passive. 6.Bc4 is developing the bishop and putting more pressure on the f7 pawn. Black has to defend this pawn. Not with the knight, but with the rook. 6...Rh7. White will always complete his long term plan again with controlling the center with 7.d4. After this move, when you visual the board, you'll realize that black has a somewhat passive position defending their pieces. There is an opening that can be played, but this opening will lead to black having an extremely passive position. White will have a lot of activity and an attacking advantage. 7...Bh6 is defending the f4 pawn, since after white played d4, white was also attacking f4. White will play 8.Nc3, attack the f4 pawn again, also developing their pieces. This opening is called the "King's Gambit Accepted: Kieseritzky, Long Whip, Jaenisch Variation".
As you can see, black's position is very passive trying to defend everything. White is better here.
5...h5 isn't something I would recommend for black, unless you are a passive player. Next I will be discussing a topic about the move 5...d6. d6 is a move that wants to push the knight away from e5 and it want's develop the bishop. This opening is called the "King's Gambit Accepted: Kieseritzky, Kolisch Defense".
White will always capture the pawn on g4 with 6.Nxg4. Although the position is still better for black, white won back their pawn, so I think white can gain some equality from this position. Our final move we will be talking about the move 5...Nf6. This is the most popular move and the best move recommended by the engine (I will always save the best or most popular for last). After 5...Nf6, this opening is called the "King's Gambit Accepted: Kieseritzky, Berlin Defense".
Nf6 is simply developing their knight. White has 3 options: 6.Bc4, d4, or Nxg4. Lets see what happens if white captures the g4 pawn. After 6.Nxg4, white wins back their pawn, but their move opens up the g file for the black rook to attack on the king side. The computer says that both sides are equal in this position. Black can play 6...d5. This opening is called the "King's Gambit Accepted: Kieseritzky, Berlin, de Riviere Variation".
This move opened a double attack on the knight on g4, so white must capture the knight on f6. After 7.Nxf6+ Qxf6, white's position is better after Nc3. Adding more pressure to the d5 pawn
After 6.d4, this opening is called the "King's Gambit Accepted: Kieseritzky, Berlin, Rubinstein Variation".
This is just a forced line that is played in the opening. 6...d5 is an option which attacks at white's center and puts pressure on the e4 pawn. White can ignore this can continue developing their pieces. 7.Bxf4, winning a pawn and developing. 7...Nex4, winning a pawn and putting the knight on an excellent square, but this knight can be challenged immediately with 8.Nd2. This opening is called the "King's Gambit Accepted: Kieseritzky, Bretano, Caro Variation".
6...d5 can be played, but this will lead to white having a better position, so I wouldn't recommend this for black. White most popular reply after 5...Nf6 is 6.Bc4. Bc4 is adding more pressure to the f7 pawn also developing a piece. Black will always play 6...d5 blocking the bishop's view. You do not want to take the pawn with the bishop, since you would lose the bishop pair, so 7.exd5 is the best move. Black has 2 options: 7...Bd6 or 7...Bg7. 7...Bg7 is the 2nd most popular move also the best move according to stockfish, so I'll go over this option. After 7...Bg7, this opening is called the "King's Gambit Accepted: Kieseritzky, Berlin, Deferred Paulsen Defense".
7...Bg7 is eyeing on the knight on e5 whenever the knight moves from f6. 8.d4 is always played. It is meant to secure the knight on e5 just in case if black decides to take the d5 pawn. The position is definitely playable from both sides. After 7...Bd6, black looks to attack the knight on e5 is the most direct way. White can O-O or play d4. Let's talk about what happens if white castles. If white 8.O-O, this opening is called the "King's Gambit Accepted: Kieseritzky, Berlin, Anderssen Defense, Rice Gambit".
White doesn't technically sacrifice a knight here. They can win back a piece in this forced line:

8.O-O will lead to black having a better game, so do not play this move.
After 8.d4, this move is securring the knight on the e5 square. Black, will play 8...Nh5. This move intends to get rid of the knight on e5 eventually. White has 3 plans depending on what type of player they are. They can do Bb5+, Nc3, or O-O. It all depends on the player. O-O is the best move according to the engine, so you can play that if you want to be more solid.
