A Zinar Puzzle From The Moscow Tournament

Another study from the great Zinar. How can white escape with a draw here?

6K1/k7/p1P5/1P6/7p/8/PP6/8 w - - 0 1

1...Kf7 seems like the only sensible try. Now:

Oops.

  1. Kf7 h3 2. Ke7 h2 3. c7 Kb7 4. Kd7 h1Q 5. c8Q+ and white has all the winning chances. So Black must try something else. 1...Kb6 2. Ke6 h3 3. Kd7 h2 4. c8Q and White still has the winning chances. Another try for Black at his 2nd move is 2...Kc7 3. Kd5 h3 4. b6+ K:b6 5. Kd6 h2 6. c7 h1Q 7. c8Q. This is certainly not won for Black either. And if 3..ab5 4. Ke4 and the White K is in the square of the h-pawn. Now the K holds the h-pawn and the a- and b-pawns just march shoulder to shoulder to within one rank of the b-pawn, then the a-pawn advances to either force liquidation of the Q-side pawns.

Kf7 definately draws..............everyone must have learned this puzzle in which white would try to chase black's pawn and at the same time try to promote his own pawn.

1.Kf7 Kb6
2.Ke6 Kc7
3.Kd5 h3
4.b6+ Kxb6
5.Kd6 h2
6.c7 h1=Q
7.c8=Q Qh2+
8.Kd7 Qd2+
9.Ke6 Qe3+
10.Kd7 Qd2+
11.Ke6 Qe3+
12.Kd7 Qd2+
It's a draw.

It's an interesting variation too. At first I couldn't find the fifth move.
1.Kf7 Kb6
2.Ke6 Kc7
3.Kd5 axb5
4.Ke4 Kxc6
5.a3 h3
6.Kf3 h2
7.Kg2 Kd5
8.b3 h1-Q
9.Kxh1 Kd4
10.a4 bxa4
11.bxa4

In the interesting variation, Alena, the 5th move isn't the only draw for white. He can move the king to the king side to win the h-pawn while leaving both pawns, for the moment, on a2 and b2 while the black king advances through d3 and c2 to attack them. However, once attacked, white must then find two only moves to draw. Can you find that line?

Here is the position I am talking about: 8/8/8/1p6/8/6K1/PPk5/8 w - - 0 1

V-1

1.b4 Kc3
2.Kf4 Kxb4

1.b4 Kb2
2.a4 bxa4
3.b5 a3
4.b6 a2
5.b7 a1=Q
6.b8=Q+
