What do you mean by "a chance"? Do you mean some tactic that would have given you a sudden advantage? Because all through the game, up to the endgame, you had excellent chances, as far as I can see. Even after blundering on move 2, (Nc6 or even d6 was better) you had good chances. Both sides played very loosely and without cohesion, that is, neither side seemed to have a plan nor ven tried to coordinate their pieces. White's initial idea seemed to be to bring out the queen and try to make threats hoping black wouldn't see one of them while, black's idea seemed to be to react to whatever white did. As such, both sides missed many chances, but at the same time, retained chances.
Try to hang onto your pawns. Fight for every pawn, unless giving it up is to your favor. Get your pieces out (develop). Coordinate your pieces and protect your pieces (don't leave any en pris) and don't block escape squares - give them some place to go if need be. Control the center. Never give a marauding queen a moment's rest.
You had plenty of chances, but you didn't avail yourself to them.
what do you think? where in the game could i even had a chance?
