The "classic" approach leads to the following sound 22.5 PG:
1. Pd2-d4 Pb7-b6 2. Fc1-d2 Pb6-b5 3. Fd2-a5 Pb5-b4
4. Cb1-d2 Pb4-b3 5. Ta1-b1 Pb3xa2 6. Pb2-b4 Pa2-a1=C
7. Pb4-b5 Ca1-b3 8. Pb5-b6 Cb3-c5 9. Pb6-b7 Cc5-e4
10. Pb7xa8=F Ce4-f6 11. Fa8-d5 Cf6-g4 12. Fd5-a2 Cg4xh2
13. Pd4-d5 Ch2-g4 14. Th1-h4 Cg4-e3 15. Th4-c4 Ce3xd1
16. Pf2-f4 Cd1-f2 17. Pg2-g4 Cf2-h3 18. Ff1-g2 Ch3xg1
19. Re1-f2 Cg1-f3 20. Rf2-g3 Cf3-d4 21. Rg3-h4 Cd4-b5
22. Rh4-h5 Cb5-a3 23. Tb1-b5
Is it the best bound found until now?
Best,
Nicolas.
