I guess Watkins has solved it further as
12.Nxb6 cxb6 (forced, all others probably lose and it should be easy for a computer to figure these fast lines out. Simple lines such as axb6?? can even be solved as a one-line forced capture sequence by me) 13.Kxg2
Now we probably have reached what Watkins called "14 remaining lines" but I'm not sure.
