Closed Game effect for White As my friend said a moment ago, the Closed Game type is bad practice for White because it brings White often to draw rather than win. 

If I want to get a better chance of winning, I should choose Open Game but be careful about counterattack.  However, there seem to be openings which are categorized in the middle [between Open game and Closed game].

I am annoyed a bit. But when I checked with Shredder, it seems rather true.

Is it true??
Closed games (1.d4) and open games (1.e4) perform equally well at high levels.

It is usually recommended that less experienced players (say, under 2000 FIDE) play open games to learn, since tactics show up more often in them, and tactics is the most important aspect of the game to become fluent in.
