What should i do for this op

Please help me

 what should i do on black to counter the opening

 cause it's hard to attack and check

why don't you show an actual game?

maybe you can use french defence or sicillian defence

 i don't know alot about chess,hmm maybe you can learn reti or torre

"1. Nf3 e5 and then I think to make king's gambit."

First, the king's gambit is a very particular opening, 1. e4 e5 2. f4, gambiting the f-pawn. Your move 1. ... e5, simply loses a pawn to 2. Nxe5, which your opponent failed to play.

"2. g3 Nh6 and then i put my horse to make sure he doesn't  make 4 step."

I'm not sure what your text means, but you are still allowing your opponent o play Nxe5. Also, knights are much more powerful near the center of the board than on the edge.

After move 6 you say you want to checkmate.  Your opponent's king is very safe. You should focus more on developing your pieces. This means, getting your last bishop into the game, getting your knight closer to the center, and getting your king to safety. In doing all this, don't just put your pieces anywhere, but them where they make threats to your opponent's pieces. 

Thnks for the help Loomis,i will use your advice..

..4 Step mean

the four step mate just by using queen and other pieces to bakeup

I Can only see 2 move
