Thanks for repairing the fen.
you have this, r2q1rk1/1b2bp1p/pp3np1/2pp4/3P4/1P1BP3/PBQ1NPPP/3R1RK1 b - - 0 1
What does "0 1" at the end of the fen indicate?
My original fen was r2q1rk1/1b2bp1p/pp3np1/2pp4/3P4/1P1BP3/PBQ1NPPP/3R1RK1 b - - bm c4;
What is the error in it?

The parser seems to expect both a "half-move clock" (the 0) and a "full-move number" (the 1). (The 0 and 1 were chosen since the true values were unknown to me.) See
here for more.

Junior in a split second and Komodo with no solution after 5 minutes.
Is this because of aggresive pruning?
All the moves seem logically forceful ( pins and captures) so what is there to prune?
