Without capturing the bishop on the 1st move how can I proceed as black ?
What are possible plans for black after the 6th move to get an advantage?

None. 1...gxh5 is a huge mistake, after which Black is definitely losing.

Without capturing bishop at 1st move how can i proceed as black ?

1...Bd4 is an excellent move, immediately threatening the pawn on e5. The positions that arise after 1...Bd4 are extremely complex. I have attempted to analyze a few with the help of the Houdini 1.5 and Stockfish 4.2 engines. Black is able to hold the position after 1...Bd4 and make a draw.
