Here you may see the problems, selected by the judge Ioannis Garoufalidis, who said the problems were easy because he decided to lower the level a bit so that more solvers can solve them, and their solutions.

With 5 points per problem, solving 12 problems you get 60 points maximum.

Some two-movers for you to solve

Here are some two-movers for you to see how easily you can solve them.
White plays, the Black tries to find adequate answer, but in the second move White mates.
You may try sacrifices, checks, anything you can think of, anyway the key-move is unique.
The solution and the comments are visible when you select the area between the brackets [  ].

Problem-770

2Qb1B2/1S1sp3/5p2/3pp2B/pp1P2r1/Sk6/1P1p4/K2bRs2 (9 + 13)

#2
Solution : [Tries : {1.Sa5+? Bxa5!}, {1.Sc5+? Sxc5!}, {1.Re3+? Sxe3!}, {1.Qc2+? Bxc2!}, {1.Qc3+? bxc3!}, {1.Qc4+? dxc4!}, {1.Qc6? [2.Qxd5#] e6!}, {1.Qc7? [2.Sa5#] Bxc7!}, {1.Qxd7? [2.Sc5# / Qxd5#] bxa3!}, {1.Qxd8? [2.Sa5#] bxa3!}

Key : 1.Qc5! [2.Qxd5#]
1…Se3 / Sxc5 / Sb6 / Be2 / Bf3 / Rxd4 / e6 / bxa3
2.Rxe3# / Sxc5# / Sa5# / Qc2# / Qc2# / Bxd1# / Qxb4# / Qc3#


Sacrificial key and many tries for careless solvers.]

5B1R/3p4/4b3/1s6/7R/5Pk1/6P1/5sK1 (6 + 5)

#2

Solution : [Tries : {1.Rg4+? Bxg4!}, {1.Rg8+? Kxh4!}, {1.Bb4? [2.Be1#] Sd2!}, {1.Bc5? [2.Bf2#] Se3!}, {1.Bd6+? Sxd6!}, {1.Bg7?  [2.Be5#] d6!}.

Key : 1.Bh6! [2.Bf4#] Bg4 2.Rxg4#

In this composition you see the Theme Elmgren, where all the black pieces have defences in the various tries.]
Problem-772

original

2BS3B/q2b1pK1/3p2p1/2prk3/3R1r2/5P2/3PP3/1Q6 (9 + 9)

#2

Solution : [Tries : {1.Sxf7+? Ke6!}, {1.Re4+? Kf5!}, {1.Rxd5+? Kxd5!}, {1.Qe4+? Rxe4!}, {1.Kh6+? / Kh7+? / Kf8+? / Kg8+? f6!}

Key : 1.Qf5+!
1…Kxd4 2.Qxf4#
1…Kxf5 2.Rxd5#, 1…Bxf5 2.Sc6#, 1…Rxf5 2.Re4#, 1…gxf5 2.Kxf7#

We see a checking key with a queen sacrifice, which can be captured by four black pieces.
The interesting thing here is the Anti-triple : Bd7xf5 / Rf4xf5 / g6xf5, where from the three mating moves Sc6 / Re4 / Kxf7 only one is valid after each black move.
