Our knight is under double-attack and pinned. Of course I can't check every possibility, but I'm sure If we lose it after Rxb1, the mate is imminent. So everything we do has to be very forcing.

1. Qc2+ and 1. Qh2+ would be forcing and keep material balance, but they don't look very strong.

I like 1. Qf7+ because black can't take the knight with 1...Kxb1 because of 2.Qb3#

After 1. Qf7 Kb2 the only forcing moves are 2. Qf2+ and 2. Rg2+. I didn't analyse Qf2+, because i suddenly noticed the "beauty" of Rg2+. Black still can't play ...Kxb1 and the king can't escape. So Qxg2 is forced. Because we are looking for a draw we can safely play 3. Qf2+. If black takes the queen, it's stalemate. If Black takes the knight we will have an easy to hold (or even win) Q vs. R+2pawns endgame. So the black king must escape via. 3...Kb3.
4. Qxg2 fails to the simple tactic ...Rb1+ 5. Ke2 Rb2+ and we're lost.

So (1. Qf7+ Kb2 2. Rg2+ Qxg2 3.Qf2+ Kb3) 4.Qxb6 keeps the pressure and I think it should be easy afterwards to get a draw by perpetual.
