black opening against e4

I am average 1500 player in standard blitze. i need a good answer to white's e4. now i answer with e5 but continue loosing too many games. i can play little tactically. positional understanding is so so. can anybody help me please

1...e5 is a fine move. The more you play it the better you'll understand it, same goes for all other reasonable responses. Try a few and then choose one you feel comfortable with. Within the reasonable openings there's no such thing as "better" response as learning opening moves' main purpose is saving time and coming up with a familiar position, not beating the opponent.

1...e5 is solid but tends to be drawish. 1...c5 (Sicilian Defense) is the most popular response and gives Black good winning chances, but is more tactical, so Black can also lose quickly. The semi-open defenses (1...e6, 1...c6, 1...d6) are good for delaying the real action until later, and for setting up similar structures regardless of what White plays. So it depends what you regard as "best". I don't take blitz seriously, so I cannot recommend openings suited for that activity.

No, just no.

The guy he's talking to is 1500 online, not a GM. Almost everything is drawish at upper levels. Telling class players an opening is drawish is utterly irrelevant.

What about 1...Nf6? Or 1...c5?

I find I prefer the Alekhine in blitz.  White can build up a decent positional advantage, but it's difficult for him to make an early and direct attack on your king.  The Pirc is similar, but a little more vulnerable to aggressive attacks.

Losing a game is not because of openings. You had played 1...e5 which is an excellent move. Try to learn more about the openings you play. 

I suggest you play Sicilian and see if it suits your style better. Since you said tactics and positional play is not your cup of tea, then it would better for you to study tactics, positional excercises rather than concentrating too much on openings.

Chess is not about openings at your stage, learn the game first.

      RUY LOPEZ
   (1 P-K4, P-K4; 2 N-KB3, N-QB3; 3 B-N5)

WHITE'S initial three moves were recorded by the author of the historic
Gottingen MS. in 1490, but it was not until 1561 that Lopez treated it
systematically in his Libro del Ajedrez. This major opening is ever
popular and kept vital by fresh analytical infusions in almost every
line. The basic concept is logical and simple--a once-removed attack
on Black's King's pawn. This constant pressure
leads to a bitter struggle in the centre and a
hair-trigger balance between attack and defence.
White secures a pull which lasts well into the
middle-game. Black has several adequate
defences, but one false step will saddle him with
a permanently cramped game before he "gets
his pieces out of the box." Some main lines
have been exhaustively analysed for over twenty
moves; many tournament games really start
from where this analysis ends, enabling both
sides to avoid consuming time on the clock. The Lopez is highly
suitable for the competitor who is out to win with White. Black can
rarely hope for more than equality. In fact, it may be said that the only
thing wrong with the Ruy Lopez is the Sicilian Defence!
