Not difficult to guess the composer of 1st prize. Masterful og typical Perkakov-study.

I am a bit disappointed that the majority of compositions features a white knight as main character. Of course, it can jump around and surprise us with tactical punches, but is there nothing attractive about other piece configurations?

I like Pervakov’s first prize, although the maze of pawns is not my cup of tea, and especially the choice between 3. Kf2 and Kg2. But the logical tries that follow are a bit less impressive. What is the white plan? After 3. Kg2, he wants to play Sc2, sacrifice with Sd4, promote his queen and then play f4+ to stop the black pawn on c2. The immediate execution of this plan fails to 11… Kxh5!, when the thematic 12. Qe5+ is met by 12… g5 or 12… Kh6. I am not 100% sure that we have purity of purpose here, since the preliminary h5-h6 removes both the availability of the h6 square and the reply g7-g5. It is also slightly annoying that 5. h6 is refuted both by 5.. Kxh6 and by 5… gxh6 6. f4+ Kh4!. Of course, these are minor points, but in a logical study, it may be fair to raise them.

I do not think that 2… Ra2 and 4… Kf6 are main lines, by the way. They are certainly thematic (“gehaltserweiternd”), but I do not see it on a par with the main line defined by the choice between 3. Kf2? and 3. Kg2!, and finishing with e4+, Qg6+ and Qxc2.

Sorry for replying late, busy days. Oleg wrote me in the meantime and said that I should look at his annotations in the official tournament report (the pdf file). He did not provide two separate tries in move 5 and 6 there. Also the “main line” comments are missing there.

Yes, I meant that the try should not stop with 11… Kxh5, but with 12. Qe5+ g5/Kh6. I guess Aliev saw this, too. Perhaps he wants to explain why he did not add these moves to the notes, or why he thinks there is no problem with purity of purpose.
