1.d4 and 2.Nc3 against everything (except 1...e5 2.dxe5/1...c5 2.d5). If they spurn ...d5, play 3.e4.
If they don't, 3.Bf4. Go through Jobava's games and charge your kingside pawns - especially against 3...Bf5 4.f3 e6. 3...e6 is met by 4.Nb5 Na6 5.e3 c6 6.Nc3 and Nf3-e5.
3...c5 4.e3 and Nf3-e5. Always charge your kingside pawns. I repeat: ALWAYS CHARGE YOUR KINGSIDE PAWNS.
