You stop central pawn advances by moving pawns to the center yourself, or controlling the center with pawns.
If your play is based on hoping your opponent misses something, it will only work so long. As you get better people won't be "cock blocking" you by playing e5, they'll simply be defending the pawn every time.
If you start responding to 1.e4 with 1...e5 and trying to play classically, there will be less bumps you as improve. So that's my suggestion for a playable position. Play classically (and strongly) by placing a pawn in the center, develop your pieces, and castle.
Ok, here it is ... Against king pawn openings move e4 i usually play e6 - the reason is because i want my oppontnet to take the center with d4 -- i play immeditely Qh4 and there a multitude of ways for me to win a free pawn!!! YEEHHH ... llol but recently my opponent have been cock blocking and playing e5 instead of d4 how do i stop whites pawn advances in the center ...
