You move the king side pawn up 2 spaces, offering it for free. This creates an open line for your rook when you castle on king side. The pawn that takes urs is also un supported and often becomes a dead peice. I've been using this open pretty religously the past 3 weeks and have had great success.
Its an old school wild style of playing.
King's Gambit as white
Latvian Gambit as Black (even wilder!)
The King's Gambit:
If you could imagine the following, simple scenario, white's play has succeeded.
White would then have ideas of playing 0-0, Bc4, and maybe Nf3-g5, to continue his pursuit of the King's weak square. Of course, things are never so simple, and black has a number of ways to complicate things. White has, of course, weakened his kingside, and this allows for all sorts of counterattacking ideas. Both sides are usually forced to accept awkward positions, and the initiative is everything. Theory has advanced quite a bit since the dashing attacks of the romantic era, but the opening still has the same reckless attacking spirit.
The Colle System:
The Colle System:
umm isn't black supposed to have 16 pieces too?
umm isn't black supposed to have 16 pieces too?
Well, it is a system, and not an opening variation. Black's response is not necessary in defining the system. It is meant to be an opening that white can play against many different responses. There are a few things to be said about the Colle System, but there are other forum threads that do this. All I will say is that it is thought to be a rather harmless opening, and is rarely seen in tournament play. The reason is not that the ideas are unsound, but simply that it is rather passive, and is not interactive enough in the opening.
The main idea of the King's Gambit (accepted) is control of the center. By gambiting a wing pawn (f4), for black's center pawn (e5) - 1. e4 e5 2.f4 exf4 - white now has accomplished two things: white has 2 center pawns and an extra tempo (since black moved his e pawn twice). White also acquired a half-opened f file with potential threats on black most vulnerable square, f7. If white is persistant and black is hesitant, white can easily transform these advantages into a winning attack - for the initial price of a pawn. If black is careful and white is over-aggressive, black can look forward to an endgame a pawn up. The King's Gambit is a very trappy, tactical opening in which either side can go wrong and go down rather quickly. But it's also played positionally, especially by black. One of chess' oldest openings, it's also one for people who like to get down and dirty, fight hand-to-hand, and balance without a net. It requires a little bit of study and a lot of courage. As mentioned, the Bishop's Opening (3. Bc4, usually followed by 3 . . . Qh4+ 4.Kf1) in the King's Gambit laughs at castling, but solves some of the problems that 3. Nf3 create. The Muzio variation throws away an entire piece, while the double Muzio tosses out two pieces.
What more could anybody ask for?
in words of intrepid Bronstein:
"if one was to pick out at random only one variation from the multifarious King's Gambit:
1. e4 e5 2. f4 exf4 3. Nf3 g5 4. Bc4 g5 5. 0-0 gxf3 6. Qxf3 Qf6 7. e5 Qxe5 8. Bxf7+ Kxf7 9. d4!
, that in itself would be sufficient to earn for the opening the eternal gratitude of chess-players."
"1. e4 e5 2. f4 exf4 3. Nf3 g5 4. Bc4 g5 5. 0-0 gxf3 6. Qxf3 Qf6 7. e5 Qxe5 8. Bxf7+ Kxf7 9. d4!"
make that ...g4 and we got a deal.
yes! it's g4 
1. e4 e5 2. f4 exf4 3. Nf3 g5 4. Bc4 g4 5. 0-0 gxf3 6. Qxf3 Qf6 7. e5 Qxe5 8. Bxf7+ Kxf7 9. d4!
now, here's a different line with d5 by black, i guess Morphy played this one:
1. e4 e5 2. f4 exf4 3. Nf3 d5 4. exd5 Bd6 5. Nc3 etc.. (so goes also the famous game Spassky vs. Bronstein 1960)
The Colle System:
Sexy... but what does that have to do with King's Gambit?
Could someone please elaborate on the King's Gambit and any other opeing you think would be beneficial.
