JAFM I believe that, same having other interesting variants, white draw after 5... Bc4 6. Rb7. 1... Rxd3 2. Rxd3 b3 3. h7 Kxh7 4. Rd7+ Kh6 5. Ra7 Bc4 6. Rb7 a4 7. Rb4 a3 8. Rxc4 a2 9. Ra4 b2 10. Rxa2 b1=Q 11. Re2 The position now is similar to the final position of the first variant that I placed (message 99888) and I don't know as black can win. Paulo Soares.
