Ertugral, however, believes Bucs had chances to claim all three points against their arch-rivals.
He said: "I'm not happy with the result. I am happy with the display and heart and the passion showed by the boys today.
"There were a couple of errors we need to look into. I think, in my opinion, we were tactically very good and organised.
"We didn't allow Chiefs at all to play and had nice breaks. But the breaks one from (Thabo) Rakhale, and one from Gift (Motupa) right in the beginning open goal, I think that should have been the decider."
A fourth straight stalemate in the league leaves Pirates with 10 points from six games - four points shy of log leaders Chiefs, who have played an extra match.
