Belgrade Internet Tourney 2017


Group A – #2 , Mate in two moves


Marjan_Kovacevic





Judge: Marjan Kovačević, International Judge

The thematic condition asked for multiple gate opening by the key-move, a motive rarely explored. Both quality and quantity of 25 anonymous entries have pleasantly surprised me!
I paid special attention to subtlety of thematic black errors: from the less sophisticated ones, leading to recapture, unguard of mating field, white line opening, or capturing by the key-piece; to the more subtle motives, like self-block, black interference, or capturing by white unit other then the key one (usually asking for additional effects of the key-move).
After the award had been completed, it turned out that one composer was author of two different joint entries (No. 4 – P.N.& A.V. and No.18 – M.B. & A.V.), against the (often criticized) rules of BIT. So, with regrets, I had to exclude the somewhat lower placed No.18.
There were two entries (Nos.19&21) equally impressive from my point of view. Since this is a thematic tourney, I gave priority to the most intensive presentation of the theme. If this was an informal tourney, the first two prizes would exchange their places in my award.
