Friendly presents for namedays

We use to give presents for the namedays.
In this post the presents are dedications.

Mr Ioannis Garoufalidis dedicates an original problem (selfmate in eight moves) to Mr Emmanuel Manolas who has his nameday on 26/12.
In return Mr Emmanuel Manolas dedicates an original problem (helpmate in 2.5 moves) to Mr Ioannis Garoufalidis who has his nameday on 7/1.

Wishes for happy holidays to everyone!

Problem-790 (original)
Ioannis Garoufalidis, GR
dedicated to Emmanuel Manolas

k2K4/p2p4/S3Q3/2P5/8/3PP3/1p6/bR1B4 (8 + 5)

1.Bf3+ d5 2.Ke7 Kb7 3.Kf6 Ka8 4.Ke5 Kb7 5.Kd4 Ka8 6.Bg4 Kb7 7.Qc6+ Kxc6 8.Rxb2 Bxb2#

The white King must go to d4 to get mated. The pawn d7 is needed to guard e4, but the black King must go to c6 to guard this pawn.
White sacrifices two strong pieces to achieve his goal.

Problem-791 (original)
Emmanuel Manolas, GR
dedicated to Ioannis Garoufalidis

1b6/8/3R4/B7/2kP4/1r3BK1/8/1r6 (5 + 4)
h#2.5, 2 solutions

(In helpmates with fractional part 0.5 in number of moves, White moves first).

1…Bc7 2.Kb5 Rd5+ 3.Ka6 Ra5#

1…Bc3 2.Ba7 Ra6 3.Kb5 Be2#

The wRd6 is pinned by the bBb8 and the wBf3 is pinned by the bRb3. In the two solutions the wBa5 unpins one of the pinned pieces, which eventually mates the black King.
