Problem 930 & 931: Vitaly Medintsev - Helpmate
vitaly.medintsev(12.12.2018) Two nice tasks from the Russian master!  930 shows a cycle of  unpins, sacrife and selfblocks, while the other  is a six solutions mammoth of selfblocks and white reciprocals!

Don't be sorry Francesco.
I'm aware about 1st Pr. 4° FRME 2018.
930 was sent to Kobulchess co-editor Seetharaman Kalyan in August. Last month I've reported that my entry is anticipated. Some time later I was asking to replace 930 with my new entry (931) but Seetharaman wrote the setting of 930 is different and it deserves to be published. I didn't mind :-)
Still, I think 930 is strongly anticipated and I'll accept any judge's decision.

P.S. both problems (930 and 1st Pr. in 4° FRME) were composed in the frame of the 20th Russian Composing Championship theme. I've congratulated the authors of 1st Pr. in 4FRME since their work is better than mine (homogeneous B2, better economy).

Thanks Francesco Simoni for your prompt response. Mr.Medintsev pointed out the FRME prize winner, but I thought since the settings are different it can be published.
My apologies for not mentioning it whie publishing.

Michal wrote the correct diagram notation in the comment #5 above. Sorry that I approve it with delay (well, I should check all commnents and approve them manually because to avoid the spam which is a lot).

But if you register an account from the option on the right side of the page, the comments will be published automatically.
