Pioneer example of Mlynka theme. Widely reproduced and well known although it was only the beginning and much nicer problems were to come in the future...

Second try of author to bring the theme into consideration of general public, more successful than the first one, more inspiring.

One of the first works with Mlynka theme awarded in tourneys. Construction is getting better and better...

1.Bh3? th. 2.Qc5#

1.f3! th. 2.fxe4#
1...Qd3 (guarding - B) 2.Sxb4#
1...Sd7 (providing flight by closing white line - C) 2.Qxd7#
1...Rf5 (unpinning - A) 2.Sxe7#

In this problem the construction is heavier, but this is partially connected with materially demanding motives of unpinning and providing flight by closing white line.
