Unexpected sacrifice of WBf3 in the first try, two changed variations between the second try and the solution. The third try 1.Bg7? truly emphasizes the "Indian" combination in the solution.[ZG]

Reciprocal change after random and corrective move by BS. Just by chance, there is thematically matching by-variation in the set play 1... b5 with same corrective play on second move.[A]
Nice mechanism of reciprocal change and additional change after thematic defence in the subvariations of 1... b5. A reminiscent of M. Vukcevich's reciprocal changes with included additional (usually reciprocal) change after thematic defences between 1st and 2nd black moves. Recently, H.-P. Rehm achieved a number of reciprocal ana cyclic changes of this kind.[ZG]

2.d3! ~ 3.Sb3 ~ 4.Sd2#

(This is the improvement of No 132. Mat Plus 8-9/1995).
The primitive version: 1.Sc5! introduces 2.f3 as a threat, and it's a real pity because the thematic variation 1...d4 is not a defence, so the black play lacks of harmony. Moreover, the only defence 1...dxe4 doesn't introduce any threat - a pity now since 2...e3 or exf3 are followed by "duals" in the usual meaning of this word.
The improved version: the theme is lightly stressed by 1.Sf4? bc4!! Curiously, the key has no threat, so that both BP-moves show in a parallel way the accurate opposition between advantage/disavantadge of the same sharp effect. 1...bc4 2.d3? c3!! so 2.d4! waiting 2...c3 3.Sb3! waiting, c2 4.Sd2# (ed3 e.p.impossible) (2...cd3 e.p.3.Sb3, ~ 4.Sd2# 2...ed3 e.p.3.Sf3, c3 4.Sh2# ); 1...b4 2.d4 ? b3!!(3.Sb3? = stalemate: ed3 e.p. impossible) so 2.d3! with a threat 3.Sb3,~4.Sd2# (2...ed3 is NOT a defence, so the dual in 3rd move has no meaning).
When I showed the 1st version by 1995 to Michel CAILLAUD, he failed to improve it - but he told me: you must try to improve it by any mean, even increasing white material. He was right and I'm now convinced a 2d WS is required. Of course, we can remove BPs h5 and h6, with Sh3 on g1 and WPe3 on e2. But the little try disappears and the key would a quite poor one: 1.e3![A]
Perfectly constructed dual avoidance motivated by the e.p. rule of immediate capture and cleverly emphasized by the tempting try 1.Sf4?.[ZG]
