I am going to put the following positions in my test suite(they seem to be easy
for the top programs but not easy without the relevant knowledge)

Can you find all the solutions?
I give a list of candidate moves and I am almost sure that the solutions are
only from the candidate moves.

[D]8/8/3R2p1/1qb4p/8/p5P1/1pk2P1P/4Q1K1 w - - 0 76

candidate moves:Rd8,Qe4,Qd1+

Movei played Rd2+ that is a losing move.

possible line 76.Rd8 g5 77.Qd1+ Kc3 78.Qf3+ Kb4 79.Qe4+ Kb3 80.Qe6+ Ka4 81.Qe4+
Qb4 82.Qc2+ Ka5 83.Ra8+ Kb5 84.Qd3+ Qc4 85.Rb8+ Bb6 86.Rxb6+ Kxb6 87.Qxc4 b1Q+
88.Kg2 and it seems that white can draw by perpetual check.

[D]8/P3R3/8/3p4/3kpK2/8/8/r7 w - - 0 62 bm Rb7,?

Movei played Kg4 that lost.

candidate moves:Rb7,Rc7,Rd7,Rf7,Rg7,Rh7
