2nd FRME #2 Award 

Juge : Dr. Paz Einat, International FIDE Judge

 

I thank the organizers for inviting me to judge this tourney. I received 22 anonymous problems for evaluation and selected 8 of them for the award.

Three more problems were excluded due to anticipations and other reasons as follows: Youness, Ben Jelloun: Black king’s star with a key granting two flights was done many times – see for example the 1894 problem by Edith Baird (A) with a key granting three flights! Other works show this with four different mates after the black king moves (see B as an example). The most valuable problems of this type are those with set mates ready for the two black king moves as done by Guglielmo & Luigi Mai (C) with two mate changes. Youness Ben Jelloun & Andreas Nievergelt: The block threat is nice but similar unpin key with more interesting play, some of it similar, was done several times, D being one example. Abdelaziz ONKOUD (Rd8/Rb4): Mate changes after Pelle movement are well-known. Zagoruiko form was shown as early as 1954 and later even without all mates being unpin mates (but with a flight giving key; see E).

Prize: Viktor Syzonenko

The Radical Changes between try 1.Sf5? and solution are connected by the royal battery play and the threats: both reappear after specific defenses (1...Qxg3 in the try & 1...Qg6+ in the solution). The unpin key and use of the royal battery in both phases, as well as the Rook/Knight battery play in the solution, leave a good impression. The set play and other tries mentioned by the author are irrelevant in my opinion.

1.Sf5? ~ 2.Kg6 A #
1...Qxg3 2.Qa1 B #
1...Sxf4/Sxf7/Se6 2.Kg5/Kxf7/Kxe6 #
but 1...Sc6!
1.Sf3! [2.Qa1 B #]
1...Qg6+ 2.Kxg6 A #
1...Qf5+ 2.Kxf5#
1...Qd4+/Qd1 2.Sxd4/Sd2#

 

1st Honourable Mention: Pavel Murashev (Russia)

One of two similar problems (possibly by the same author) working along the WCCT10 theme. I find the execution here preferable as the theme is shown in a clearer way and the changes are better. There is a function change of the Sc4 mate and several changes after the BR correction play, but with Bd6 being the only mate in the try 1.Se8?.

1.e:d3? [2.Sc4 A #]
1... Rc5 a 2.d4# but 1... R:d6 b ! (2.Q:d6#?) 1.Rf4? [2.Sc4 A #]
1... R:d6 b 2.B:d6# (2.Q:d6#?- pin)
but 1... Rc5 a ! (2.Q:c5#?)
1.Se8? [2.Qe6#] 1...Rd~ x 2.Bd6# 1...Rc5 a , Rd6 b 2.B(x)d6# (2.Q:c5, Q:d6#? - pin) 1...R:d7! 2.S:d7# 1...Rd4! 2.e:d4#
but 1...Rh6!
1.e4! [2.Q:d5#]
1...Rd~ x 2.Sc4 A #
1...Rc5! a 2.Q:c5# 1...R:d6! b 2.Q:d6# 1...Rd4! 2.c:d4# 1...Q:e4 2.R:e4#
1...S:c6 2.S:c6#

 

2 nd Honourable Mention: Petro Novitsky (Ukraine)

There are three mate changes after 1...Bg8, three after 1...Sxc3 and additional two changes after 1...Sxd4 making this almost a 3x3 Zagoruiko. The changes following the BS defenses are wellknown (see F) but there are enough additional elements here to deserve a place in the award.

1...Bg8 a 2.Qg6 # (1...g5 2.Q*h7 #)
1.Qd7 ? [2.Q*b5 #]
1...Bg8 a 2.Qf5 # 1...S*c3 b 2.Q*h3 #
but 1...S*d4 c !
1.Qb3 ? [2.Q*b5 #]
1...S*c3 b 2.Q*c3 # 1...S*d4 c 2.c*d4 # (1...b4 2.Qc4 #)
but 1...Bg8 ![a]
1.Qd5 ! [2.Q*b5 #]
1...Bg8[a] 2.Qe4 # 1...S*c3 [b]2.B*c3 # 1...S*d4 [c] 2.Q*d4 # 1...Sc5/Sc7 2.Sb4 #

 

3 rd Honourable Mention: Valery Shanshin

Change of function: the mates on the two black-king moves to the flight squares, granted by the key, appear as 1st move (Bb8) and threat (S:g6) in the try play. Additionally, there is both a transfer and function change of the mate Qe3. There is some resemblance to G and some lack of unity to my taste.

1…R:d6 2.Qе3 X #
1.Bc5? – 2.Qe3 X #
1…Bd4 a 2.B:d4#
but 1…R:a5 b !
1.Bb8 A ? – 2.Qe3 X #
1…R:a5 b 2.d7#
but 1…Bd4 a !
1.Sc7? – 2.S:g6 B # 1…K:f4 2.Qe3 X #
but 1…Rh6!
1.Sc5! – 2.Sd3#
1…K:d6 2.Bb8 A # 1…K:f4 2.S:g6 B # (2.Qe3?)

 

1 st Commendation: Zoltan Labai

A classical style mutate with a good key but WRd1 is a pity. I did not find any anticipations..

1…g4 a 2.Qxf4#
1…dxc4 b 2.Bxe5#
1.Bd4~ zz 1…g4 !
1.Bf2 ! zz
1…g4 a 2.Bh4# 1…dxc4 b 2.Rd6# 1…e4 2.Bd4# 1…d4 2. Sh5#. 1…b7~ 2.Rxc6# 1…Bf4-c1 2.B(x)e3# 1…Bf4-h2 2.B(x)g3#

 

2 nd Commendation: Abdelaziz ONKOUD (Maroc)

Interesting logical play: the two unpins defeat the try on c7 and only one of them defeats the further two tries. The move to f4, covering both g4 & g5 works.

1.Dç7? [2.Th6‡]
1…Cg6 2.F×g6‡ 1…Cf7 2.Fg6‡
mais 1…Cd6!, d6!
1.Dg3? [2.Th6‡]
1…Cd6 2.D×g4‡ 1…Cg6 2.F×g6‡ 1…Cf7 2.Fg6‡
mais 1…d6!
1.Dé5? [2.Th6‡] 1…Cg6 2.F×g6‡ 1…Cf7 2.Fg6‡ 1…d6 2.D×g5‡
mais 1…Cd6!
1.Df4! [2.Th6‡]
1…Cd6 2.D×g4‡ 1…Cg6 2.F×g6‡ 1…Cf7 2.Fg6‡ 1…d6 2.D×g5‡

 

3 rd Commendation: Miroslav Svítek Mělník, (Czech Republic)

A nice mix of mate changes and transfers but I have a feeling that this matrix could have been better exploited.

1…B:c4 a 2.Bd4 A #
1…c:d6 x 2.B:d6 X #
(1.d:c7? [2.Bd6 X #] but 1…d5! 1.c:d7? zz. but 1…c6!)
1.Se7? zz.
1…c:d6! (x) 1…B:c4 a 2.Se4 B # 1…d:c6 b 2.Q:c6#
1.Se3! zz
1…B:c4 a 2.R:c4# 1…d:c6 b 2.Se4 B # 1…c:d6 x 2.Bd4 A # 1…Ba6~ 2.R(:)b5#

 

4 th Commendation: Luis Gómez (Spain)

Good tries by the white bishop with the other two threats always existing as variation mates.

1.Be3 ? [2.Sf4 A #]
1...f*g5 2.Qe5 B # 1...B*d6 2.Qc4 C # 1...Be7 2.R*e7 # 1...Q*e3 2.R*e3 #
but 1...Qf1 !
1.B*f6 ? [2.Qe5 B #]
1...Qe1 2.Sf4 A # 1...B*d6 2.Qc4 C # 1...Be7 2.R*e7 # 1...Qe3 2.R*e3 #
but 1...Q*g5 !
1.Be5 ! [2.Qc4 C # ]
1...Qh1 2.Sf4 A # 1...f*e5 2.Q*e5 B #
