### 4th International Solving Contest - cooked study?

The following study which was given for solving maybe is cooked:

L.Falk, Réti MT 1989, 2.hm
(= 4+5 )

draw

1.Rb8+ Kd7 2.Rb7+ Kc6 3.Rb6+ Kd7 4.Rb7+ Kxd6 5.Rb4! Ra1+ [but 5...Rc3+! 6.Kd2 Rc4 7.Rb6+ Kd7! 8.Kxe3 (8.Rb7+ Kc8–+) 8...Rc7!–+)] 6.Kb2 Be5+ 7.Bd4 a3+ 8.Kxa1 Nc2+ 9.Kb1 Nxb4 10.Bb2! Bxb2 stalemate

Am I right?

Yes, it's cooked!

after 5...Rc3+! etc, 7...Kd7! 8.Kxe3 Rc7! 9.Rg6 Rxa7!! 10.Rg7+ Kc6 11.Rxa7 Bg1+ 12.Kd3 Bxa7 13.Kc4 Bc5 wins for black

In view of this black should play 2...Kxd6 to reach this variation two moves earlier.

Can anybody post all problems from the contest? Thanks.

I could send the two missing problems only by a PM.

study 4 contains a minor dual (at the last move) but nothing destroying
