Hello!!!!
I am joining recently Chessnia Bulletin, in 15 or 20 minutes I got this solution "to rook's endgames"
White move and win
[FEN "8/4Pk2/Pp2p3/2p1p2K/8/1P3P2/7R/3r4 w - - 0 1"]
1. e8=Q+ Kxe8 2. Kg6
(2. a7 Ra1 3. Kg6 Rxa7
(3...Kd7 4. Rh7+ Kd6 5. Kf6 Ra3 6. Re7 Kc6 7. Rxe6+ Kb5 8. Kxe5
Rxa7 9. f4 Ra6 10. f5 Kb4 11. f6 Kxb3 12. f7 Ra8 13. Re8 Rxe8+
14. fxe8=Q)
4. Rh8+ Kd7 5. Rh7+ Kc6 6. Rxa7 Kb5 7. Re7 Kb4 8. Rxe6 b5 9. Rxe5
Kxb3 10. Rxc5 Kb4 11. Rxb5+ Kxb5 12. f4 Kc5 13. f5 Kd5 14. f6 Ke6
15. f7 Ke7 16. Kg7 Ke6 17. f8=Q)
2...Ke7 3. Rh7+ Kd6 4. Kf6 Ra1 5. a7 Ra3 6. Re7 *
How it continues ?
it isn't so predictable and requires more lines, but most of us having coincidance with these firts variants.... i think.
