Nxg2 does force a draw. Also if white goes astray black could win. I'm wondering now if a quiet move like Rb8 might be ok as it threatens Nxg2.

This sequence of moves looks strong for white: [FEN "r4rk1/5ppp/p2pbb2/3B3Q/qp2p3/4B3/PPP2P1P/2KR2R1 w - - 0 1"] 1. Rxg7+ Bxg7 2. Rg1 Rfc8 3. Rxg7+ Kxg7 4. Qh6+ Kg8 5. Bxe4 b3 6. Bxh7+ Kh8 7. Bf5+ Kg8 8. Qh7+ Kf8 9. Bh6+ Ke8 10. Qg8+ Kd7 11. Qxf7+ Kc6 12. Bxe6 Qe4 13. Qd7+ Kb6 14. Be3+ Ka5 15. Bxb3 But being this length is probably beyond the scope of what is expected of this revised suite. Is this similar to what Ferret and you are finding?
