Hello Milan
Do you remember this problem?

Y Cheylan 2nd HM., Mat Plus, 1994

I was quite taken with it and started to reconstruct it last night. I came up with the following.

1..Se2-d4 2.Bd3-e2 thr 3.Sc5-d3# 1..Sb5-d4 2.Bd3-b5 thr 3.Sc5-d3#

The first move try of 1.B~? is not now there, and this may be important to some. Of course 2.B~? does not work as a threat because of 1...Qd7! I have saved a wR and a bR and have used a bB instead of a bP. Is this saving important? What do you think?

all the best

You are right, of course, the undefined threat is still a flaw. I tried very hard to find a better threat, but with no success. Yes, please quote the position in the column. Perhaps somebody else will be able to eliminate the flaw! Then we will have a fine problem.

At least, here are the improved diagrams :)
