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.
Problem-625 Nikos Pergialis original  8/5R2/4p1K1/1Q6/1S1B2s1/3R4/2S1k3/r7 (7 + 4) #2 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. |
Problem-626 Nikos Pergialis original  1r6/4R3/2k1K3/7B/S1P1Sp2/8/4P3/7r (7 + 4) #2 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. |
Problem-627 Nikos Pergialis original  8/8/5S2/Q1pP4/8/2P2kP1/3K2p1/4B2s (7 + 4) #2 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]. |
Problem-628 Nikos Pergialis original  8/8/8/8/1p1R4/SRp5/K1p5/2k5 (4 + 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)". |
Problem-629 Nikos Pergialis original  8/8/8/7k/8/5SR1/8/6K1 (3 + 1) #6 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. |
