I’m happy to welcome a new author on the site – Ioannis Garoufalidis, Greece!

No.138 – s#10 by Ioannis Garoufalidis – A nice miniature with surprising model mate – all white pieces block! (JV)

No.139 – hs#3 by Ioannis Garoufalidis – Nice Meredith with difficult solutions. (JV)

Definition:

Maximummer – Black must play the geometrically longst move or may choose from among longest moves of equal length, distances being measured from the center of each square. Diagonal and oblique distances are measured from the orthogonal coordinates by using Pythagora’s theorem (take the square root of the sum of the squares of the orthogonal distances). All other orthodox chess rules apply.

KoBul Kings  – When a piece (not a pawn) of his own side is captured, a King transforms into a Royal piece of the same type as the captured one. When the King is in the form of any Royal piece and there is a capture of one of the pawns of his own side, he becomes a normal King again. Сaptures are illegal if their result is self-cheсk because of the transformation of the Кings according to KoBul rules. Castling is allowed only if the KoBul King is on his initial square in the form of a normal King and if he has not already moved; however he may already have been transformed. In the case of capture by a King in AntiCirce he is reborn on his initial square and may castle. If the capture is by a King which is in the form of some Royal piece, he is reborn on the initial square of that piece.

 No.138 Ioannis Garoufalidis Greece original – 28.09.2012   s#10                                   (4+3)     C- Maximummer          Solution: (click to show/hide)   1.Kg5! Bg8 2.Kf6 Ba2 3.Ke7 Bg8 4.Kxd7 Ba2 5.Kc8 6.Rd8 7.Bc7 8.Be4+ Bd5 9.Bf5 Bh1 10.Bd7 Bb7# No.139 Ioannis Garoufalidis Greece original – 29.09.2012   hs#3             b) Ba1→b1             (6+5) Kobul Kings     Solution: (click to show/hide)   a) 1.Sf6 Bxf6 (wrSh1) 2.Rg8 Bh4 3.Rg5 g2# b) 1.c8=B Kg6 2.Bb7 Kf5 3.Be4+ Bxe4 ( wrBh1)#   At first solution White sacrifice it’s Knight and wK is mated at Knight phase by black (zugswang position for black If bBh4 takes wRg5 then wK becomes wRK and checks bK so bB is pinned at the end). At second solution an unexpected bK route to f5 is combined with a white pawn bishop subpromotion. (Author)

I am not a fan of ANI (unrelated solutions). But in N.139, both solutions are interesting, though everyone I think will like the first solution with the block ending with the black bishop pin ! I wish there was a way of adding a related second solution. !!
