I tried my best in this game, but lost. I NEED HELP!!!

Hey friends, I am desperately in need of a suggestion here. I have been playing a correspondence game (1 day/turn). I played my moves after lots of thinking. I had my plans and strategies. I played utmost carefully, analyzing each and every move I made, looking sharply for any bad move of my opponent to punish. I was playing the best I could. BUT STILL I LOST! I had no option but to resign at move 28.

Please friends, give me your insights on this game. Why did I lose, where do you think I need improvement?

6...e5 loses a pawn for no compensation.

I don't get 6 e5 either. Why would you try to break open the centre of the board when you have only developed half your pieces?

@absk-kr-singh Your opponent was strong. Play more carefully next time.

@tpr But I knew I would recapture the pawn later. See the twelfth move (12. ...Nxe5). We had equal material. I lost a material on 18th move when my opponent took my most important pawn with his bishop (18. Bxg6) and I could do nothing.

@maxdribble Ok so that's the problem. I should have developed my pieces first before 6.. e5 No wonder why engine was suggesting 6... Nc6

It seems to me that you have not drawn conclusions from this game. In order to capture the white pawn e5 and level the material, you made a couple of moves that were useless for development, while your opponent, opposite, developed his pieces and at the same time attacked, as if hammering nails into a box. You were defeated quite deservedly.

@ujcn I've never thought this way. Piece development is must before attacking.

I have another confusion here if I may ask you, does this rule apply in openings like Sicilian where black plays multiple pawn moves while white gets fully developed?

@absk-kr-singh #6
Any developing move is better than e7-e5. But there is also an ideological move c7-c5! The idea is that Black does not consider White's move e4-e5 to be dangerous for himself, and in this case starts a counter-attack on White's far-advanced pawns.
