Miodrag_Mladenovic





Judge: Miodrag Mladenović

I received 44 problems without author names from neutral judge Borislav Gadjanski. The quality of problems was very good since there was very short amount of time available for composing. After reviewing problems I found out there are three non-thematic problems: #10 (RK), #14 (YB) and #32 (D-C G). Also, there is one problem with three WRs. Although it was not specifically stated in the announcement of the tournament that it was forbidden I found out there is no justification for using the third rook. So I did not rank this problem at all. I decided to rank 17 problems:
