King's gambit
A small analysis on the Opening moves (till the Knight Sac) you commented:
- 4.h3: As you say, it looses a tempo. I'd play Bc4, d3 or Nc3. Moving f5 is not so common, as it locks the f file, which you want open when playing the King's Gambit. I would not do it unless it's forced or you can get something in return.
- 6.f5: What I said before. White locks the f file without compensation. Again, d3, Bc4 or even Nc3 or exf5 would be better.
- 8.g4: supports the weak f5 pawn, but weakens white's kingside, and prevents him to 0-0, as his kingside is weak. His Light Squared Bishop is now trapped in very nicely.
- 9.Bh6: looses a tempo. Black happily moves the rook to e8 and leaves white's Dark Squared Bishop in a very bad position.
- 10.Nd2??: Horrible blunder. Weakens white's overextended kingside, moves a piece twice before finishing develpoment and all of this serving apparently no purpose.
- 10...Nxe4!: I like this move. Whie is forced to retake due to the pressure the knight gives to his position.
Looks like white messed up with an opening he didn't know how to handle properly trying to surprise you. This game shows how white should NOT play the King's Gambit.
Thank you pauix. I want to learn King's gambit. I won a few games earlier with it. And want to make it my main opening for some time.
I was trying to push pawns to gain more kingside space, hoping to smother the opponent, but did not realise the weaknesses it created behind the pushed pawns.
Also ...Bc4 disallowed me to castle on kingside. I should have addressed that with c3-d4 before anything else.
