Set up d4, c4 and a g2-bishop on the long diagonal, castle, and use the c4-d5 tension and the bishop's reach to pressure Black's centre and queenside for the whole game.
Strengths
The g2-bishop is everything: it eyes the long diagonal toward b7 and d5, giving White durable pressure even into the endgame.
If Black grabs the c4 pawn (...dxc4), White usually doesn't rush to recapture — moves like Qc2, a4 or Ne5 regain it while keeping the initiative.
Central tension between c4 and d5 lets White choose between recapturing on d5 or keeping the squeeze; patience is rewarded.
It's a positional, low-risk opening: you rarely get mated, and the bishop pressure often pays off in a better endgame.
Watch out for
Don't panic when Black takes on c4 — chasing the pawn immediately can cost the initiative; regain it calmly with Qc2, a4 or Ne5.
Trading off or shutting in the g2-bishop without compensation throws away your main trump.
Drifting without a plan lets Black free up with ...c5 or ...dxc4 and ...b5; keep the pressure and the tension working for you.
