Key: 1.Rc7! (zz).
Variations: 1...Kd8 2.Rc8#, 1...Rb8+ 2.axb8=Q# / axb8=R#, 1...R~ 2.Rc8# / Qg8#, 1...Rd3 2.Qg8#, 1...Rf3 2.Rc8#.

Problem-149, Zappas, #3
Tries: {1.Rxf5? / Rxb7? / Be8? / Bd7? / Bxb7? Kd4!}, {1.d4+? Kxd4!}, {1.Sa6+? Kxc6!}, {1.Kc3? bxc6!}.

Problem-150, Siaperas, #4
Try: {1.Rd7? Bd6!}
Key: 1.Rg7! [2.Bh5 ~ / Sf7~ (if black plays anywhere or if he plays somewhere with Sf7, then) 3.Bxf7# / Re7#]

If 1...Bb8 (Bristol line clearance)
2.Bh5 Qc7 (we understand now that the black pawns a5 and b7 were placed there to void checks from the black Queen Qc7)
3.Bg6 [4.Bf5#]
3...Qf4 / Qe5 4.Bxf7#
3...Sd6 4.Re5# (Note that in the initial position this square was guarded by three black forces!).

If 1...Bd6
2.Bh5 [3.Bxf7#]
2...Se5 3.dxe5 [4.Bf7#] Sxe4 4.Bg4#
2...Sg5 / Sh8 / Sd8 3.Be8 and 4.Bd7#

Problem-151, Fragoulis, study +
Key: 1.Sc2! Kxa4 2.Sa1!
2...Kb4 3.Kxe7 a4 4.Kd6 a3 5.Sc2+ ~ 6.bxa3 and white wins
2...e5 3.Ke6 e4 4.Kd5 e3 5.Kc4 e2 6.Sc2 e1=Q 7.b3#

Problem-152, Paizis, h#3
1.Kxf6 Se4+ 2.Kf7 Kc7 3.Ke8 Sd6#
1.Sg8 f7 2.Bc5 fxg8=Q 3.Kd6 Qe6#

Problem-153, Moutecidis, s#2 (*)
Phase of set play : (*)
1...Kxc7 2.fxe8=Q (zugzwang, zz, and black is forced to continue by giving mate) Sxe3# / c2# / Qxg4#
1...Bxf7 2.e8=S (zz)

Tries: {1.Rh5? / Rh6? / Rh8? Bxf7!}, {1.c8=B+? Kc7!}, {1.Bc6+? / f8=S+? Kxc7!}, {1.fxe8=Q+? / fxe8=S? / fxe8=R? Kxe8!}.

Phase of real play : Key: 1.Sb5! (zz)
1...Kc8 2.fxe8=B (zz)
1...Bxf7 2.e8=R (zz)

Since it has achieved the four promotions in the solution, the problem is an allumwandlung (AUW).
