Please, I need your help !

1) Is 1...Kf8 winning ?

2) Is 1.. Qxc4 drawish ?

Reference : http://membres.multimania.fr/albillo/book0402.htm

"This outstanding book is part of the essential Encyclopaedia of Chess Endings"..."The analysis includes also six main variations, fully commented using the proprietary code system."
But I don't have access to this variations (and engines may be refute them now !).


It is indeed the study #1104 of Encyclopedia of Chess Endings of 1989. I have transcribed all the variations, hoping no typos:

Quote:
1104. 1... Kf8!! [1 ... Qc4 2.
Nfe4=] 2. d6 [2. Nce4 Qc4 3. Ng5 Qd5
4. Ne6 Ke7 with the idea c4-+; 2.Nfe4 Qf4 3.
Kh3 Qf3 4. Kh2 Qg4 5. f6 Qf4 6. Kg1
g4 7. d6 Ke8-+; 2. f6 Qc4 3. Nfe4 Qf1
with the idea Qf4-+] Qc4 3. Nfe4 Qf1 [with the idea Qf4]
4. Nf2 only move [4. d7 Qd3 -+] Qc1 5. Nce4
Qe3 6. Kg2 c4 7.f6 Ke8 8. Ng3 c3 9.
d7 Kd7 10. f7 Qe7 11. Nd3 c2 12. Nf5
Qf7 13. Ne5 Ke6 0 : 1 [Skembris]


I hope that this stuff will be useful for future analysis in this thread. Have fun!

Regards from Spain.

Thanks, Jesús !
The 1st step of the verification is :
After 1 ... Qc4 2. Nfe4
[D]8/5k2/p7/2pP1Pp1/2q1N1P1/2N3K1/P7/8 b - - 1 2

Do engines don't find a way to make progress (= is it a fortress) ?
