Original Problems (pages 1-10)

I’d like to present the first 4 original problems of this site: 2 my own problems: No.1 – light miniature with KoBul Kings and No.3 – the one of my first helpmates. No.2 – an interesting problem with critical moves by the known Indian composer who also сooperates with this site a lot! №4 – a nice problem with Маsand Chess (a little sorry, that in 1 solution only).

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 (the definition from www.kobulchess.com). The perfect examples of KoBul Kings you can see in the Award of KoBulChess TT 2012.

Masand: A unit which moves and actively checks changes the colour of all the units – enemy and its own (not Ks) – which it observes after the move. A checking rear (non-moving) piece of a battery would not recolour the units it observes.

No.1 Julia Vysotska (Latvia) original – h#2,5*                                        (3+4) KoBul Kings White Royal piece Se2 – 1… … 2.Sf7 f5 3.Bf4 rSxf4 [brK=rB] # – not 4.rBxf3(wrS=wK)?? – self-check!! 1…rSd4 2.Sg4 rSf5 3.Bf6 fxg4 [brK=rS] # – not 4.rSxf4(wrS=wK)?? – self-check!! – The black King in the rB/rS phases can’t capture the white pawns f3/f4 because it transforms white rS into the King phase giving the self-check. Sacrifices of the black S/B with the transformation of the black King. (Author)

No.2 Seetharaman Kalyan (India) original – hs#2,5          b) LEg8->g7         (4+8) LEOs: a4, a5, g8 – a) 1….LEa2 2. LEa8 LE5a3! 3. Sf8+ LExa8# b) 1….LEa7 2. LEa1 LE4a6! 3. Sf6+ LEna1# – Critical moves from the both sides. White creates two anti-batteries S/LEO (orthogonal and diagonal). Аbout black play: it can be called a Doubled Bristol theme also. Actually all Bristols involve movement over a critical square. Perhaps the name “Double-headed Bristol” is more descriptive here. Very rarely Bristol pieces move in both directions. (Author)

–   No.3 Julia Vysotska (Latvia) original – h#2            2 solutions               (4+5)   – I. 1.B:d3 Se2 + 2.Kc4 Sd2 # II. 1.S:e4 Sf5 + 2.Kc5 d4 # – Zilahi, vacation of square, model mates. (Author)

–   No.4 Ivan Bryukhanov (Ukraine) original – h#4                                              (1+4) Masand – 1.b3 Kd6 2.Se4(wPc3)+ Kd7 3.Sc5(wPb3)+ Kc6 4.Ka5 b4(wSc5)# – Ideal-mate. (Author)
