Nikos Pergialis, 5 compositions

We proceed with 5 more compositions of the Greek problemist Nikos Pergialis, the last rebetis (composer and singer of Rebetiko songs).
Here are three twomovers and two more-movers, one 4-mover and one 6-mover. After the solutions we write the themes in these problems. I say again that he likes compositions with at most 12 pieces (Meredith) and Ideal mates.


Nikos Pergialis

8/5R2/4p1K1/1Q6/1S1B2s1/3R4/2S1k3/r7 (7 + 4)

Tries : [1.Bc3? Sf6!], [1.Rd1+? Kxd1!], [1.Rd2+? Kxd2!], [1.Rf2+? A Sxf2!], [1.Qe5+? B Sxe5+!], [1.Qf5? exf5!], [1.Qh5? Rf1!]

Key : 1.Qg5! [2.Rd2# / Qd2# / Qxg4#] (The Queen abandons the battery).
1...Sf2 2.Rxf2# A
1...Se3 2.Qxe3#
1...Se5+ 2.Qxe5# B
1...Sf6 2.Qg2#

Theme Vladimirov : [Two try-moves are also mate-moves in two variations]. They are denoted as Α and Β.
Theme Elmgren : [At least three black pieces are defending in tries.]. Here are defending all the black pieces.
Theme Option : [The same white piece is making at-least two try-moves and the key-move]. Here, the wQ.
Theme Grab : [The defending piece is captured in more than two variations]. Here, the black Knight is captured in three variations.
Anti-Quadruple : The black Knight is defending from four positions, with result four different mates. Duel Black - White.


Nikos Pergialis

1r6/4R3/2k1K3/7B/S1P1Sp2/8/4P3/7r  (7 + 4)

Key: 1.Bf3! [2.Sd2# / Sc3# / Sc5# / Sd6# / Sf6# / Sg5# / Sg3# / Sf2#]
1...Rd1 2.Sd2#
1...Rb3 2.Sc3#
1...Rb5 2.Sc5#
1...Rd8 2.Sd6#
1...Rh6+ 2.Sf6#
1...Rh5 2.Sg5#
1...Rh3 2.Sg3#
1...Rf1 2.Sf2#

The key creates a Knight-Bishop battery but exposes the wK to check danger.
Theme White Knight Wheel [the wSe4 moves to eight positions. Task!]. The lifting of this Knight fires the battery and creates eight threats.
Theme Pseudo-Fleck : [The multiple key-threats are separated with eight from the black defences]. It is a Pseudo-Fleck because there are black moves not separating the key-threats.
Duel Black-White. There are mates with mirror symmetry.


Nikos Pergialis

8/8/5S2/Q1pP4/8/2P2kP1/3K2p1/4B2s  (7 + 4)

Key : 1.Qa4! [2.Qd1# / Qe4# / Qf4# / Qg4#]
1…c4 2.Qd1#
1…g1=Q/R/S/B 2.Qe4#
1…Sf2 2.Qf4#
1…Sxg3 2.Qg4#

Theme Fleck : [All the multiple key-threats are separated with the black defences].


Nikos Pergialis

8/8/8/8/1p1R4/SRp5/K1p5/2k5  (4 + 4)

Key : 1.Sxc2!
1…Kxc2 2.Rb1 b3+ 3.Rxb3 Kc1 4.Rxc3#

Key with a pseudo-sacrifice of the wS, which gives a flight to bK.
Switchback of the wR in its initial position. Switchback of the bK.
Ideal mate.

Nikos Pergialis says:
"Re ri'hno za'ria (Hey, I throw the dice) /
ke fe'rno do'rtia (and I bring four and four) /
re stis ma'vris go'menas (hey, at black broad's) /
tin po'rta (the door)".


Nikos Pergialis

8/8/8/7k/8/5SR1/8/6K1  (3 + 1)

Key : 1.Rg8!
1…Kh6 2.Sg5 Kh5 3.Sf7 Kh4 4.Kg2 Kh5 5.Kf3 Kh4 6.Rh8#

Weningsteiner (only 4 pieces). Each white piece makes 2 moves.
Switchback of the bK. Ideal mat.

Nikos Pergialis says:
"Re ri'hno za'ria (Hey, I throw the dice) /
ke fe'rno exa'res (and I bring six and six) /
re mas ta tro'ne (hey, they eat our money) /
i alania'res (the broads in the street)".

One of our readers, Alotan, has informed us that this problem is anticipated: "The #6 (Νο.629) reminds me of something. A search in WinChloe gives the (Kh1, Rf2, Sf3 - Kd1), #6, Hilmar Ebert, Problem 1977: 1.Ra2! etc.. With such a few pieces, it is almost impossible to avoid anticipation. Especially for orthodox problems, which are almost exhausted".
These things happen! We will continue with other compositions of Nikos Pergialis.
