Kc4 6. f4 Kxd4 7. f5 exf5 8. e6 Now instead of Kd3 8. .. b2 There follows either : 9.Rxb2 cxb2 10. Bxb2+ Ke4 11.e7 f4+ here the endgame already starts diving into my 4 man tablebases... maybe 12.Kf2 Bd7 13.Bc1 d4 and white will have real trouble to hold things together. From here I've removed all but the 3 black passers and the white bishop (blacks bishop is the only mobile piece in there) and I get minus 8 with 4 man tablebases, so I estimate the line with the other pieces is won too. or 9.e7 b1Q 10.e8Q and now the question is if black can force a win here he has 'first check' but I don't see a win yet -- GCP
