Problem 753: Kenan Velikhanov - Helpmate
kenan.velikhanov(01.09.2016) Nice helpmate showing four selfblocks on the same square. Can it escape anticipation?

Thanks Vitaly for these nice examples. The six-fold task of Moser is really nice achievement. Of course Ivanov example shows the four-fold Stochi with nice dual avoidance effects!

Right decision, Kenan!
The third one in my selection (99528 by Ivan Soroka) is quite a miracle and the last one (P0530509 by Hans Moser) is a real task!

You are right. The Ivanow task is indeed a miracle.

It's curious that in the 3rd WCCT the 2nd place and other problems had similar scheme with selfblocks. See the following,
Z. Janevski, 2nd pl. 3rd WCCT 84-88
2b1NbN1/2P5/4npp1/4rk2/4nqr1/8/8/7K (4+10)
H#2 4.1.1.1
The Vetter problem is very appreciable since it's the oldest in the list (1975), however I think the Janevsky problem is nice because in it W1 and W2 moves are performed by different pieces.
Soroka problem is probably the best showed here, despite also in it White moves always the same piece.
