KoBul compositions, anyone?

Today is the birthday of mr. Diyan Kostantinov, a young excellent composer from Bulgaria, (happy birthday Diyan!)

He has introduced a new fairy condition, the KoBul kings. A KoBul king moves and captures like the most recent friendly piece that was captured. It becomes again a normal king when a friendly pawn is captured.

It is a condition with very interesting strategic and tactical implications. The solving software, (example : WinChloe), recognizes the new condition.

A formal composing tourney is announced, see http://kobulchess.com/en/tournaments/anouncements/29-kobulchesscom-tt.html .

I am presenting here two original KoBul compositions, very very simple, with their solutions.
