Perhaps you are refering to A P Sokolsky's "Sokolsky's Opening. "
Use 1b4 to develop and keep an initiative on the Queenside.
Put (fianchetto) your Queen's Bishop on the long diagonal.
Prevent Black from forming a strong centre (in other words, prevent Black from taking advantage of your neglecting to advance your centre pawns in your first moves).
That's worth the sacrifice of your king's pawn.
Deploy your king's bishop to c4 to weaken Black's grip on the light-coloured squares.
Use your Queen to keep keep black's queen's bishop stuck on c8 and not able to deploy to e6.
If you sacked your king's pawn on the third move to get the initiative, ten moves later you should still have it.
Even when Black succeeds in castling kingside.
With the sac, you've bought a promising middlegame position. Black can play passively, or reluctantly swap pawns to relieve the tension in the centre.
By about move 23 to 25, d5 or g5 should be beckoning your knight to come attack Black's queen ( for example) .
Or, lots of other choice threats should be calling to you at this stage of the Sokolsky.
Above all, keep your pieces active.
Enjoy the fun.
