Thanks Richard - I will use your (and if others post , theirs :) ) pv as
reference to furthur analyse the position.

Due to some critical bugs in my search (Singular extension in endgame and null
move zugwang checking condition being wrong) , my program got busted by a 8 ply
search that lasted for 30 secs !
So the game ended in a loss due to time problems.
But I think the limited endgame knowledge in my engine might have caused
something to get overevaluated.

Thanks again,
