 No.1506 Vlaicu Crișan & S.K.Balasubramanian Romania / India original – 14.05.2020 Solutions: (click to show/hide) white Pf4e2 Bc6f7 Re4c7 Kd6 black Pg4c4a6b6g6h7 Kg3 Bd5e8 Rd4e7 hs#3.5         b) Kg3→h6             (7+11) Superguards Take&Make a) 1...Be8*f7-g8 2.Rc7*e7-f7 {display-departure-file} Rd4*e4-e7 3.Bc6*d5-g2 Kg3*g2-a8 { } 4.Kd6*e7-a7+ Bg8*f7-b7 # b) bKg3-->h6 1...Rd4*e4-e3 {display-departure-file} 2.Bc6*d5-e4 {display-departure-file} Be8*f7-d5 3.Rc7*e7-g7 Kh6*g7-a7 { } 4.Kd6*d5-a8 + Re3*e4-b7 # { (C+ by Popeye 4.83)} Features: Four pairs of pieces exchange functions: Rc7/Bc6, Re4/Bf7, Rd4/Be8 and Re7/Bd5. All the moves are 100% Take&Make specific. Full orthogonal-diagonal correspondence. The first and the last moves are played by the same piece capturing a white piece on the same square. Each move is made possible by the previous move(s), so the interplay is highly genuine. The main strategic motif is line clearance: both Kings have to move to a7 and a8 along the thematic lines a7-g7/a8-g2, swapping their final places in the twins. For these journeys the white Bishop and Rook have to reach the adjacent squares to black King (g2 and g7). Apparently the black Rook and Bishop are already ideally placed on the right squares (e7 and d5) to guide the white K to the destination. Actually they have to be first annihilated and replaced by their siblings on the same squares. Both mates are Superguards specific: Black captures the guarding unit of the white King and moves to a square (b7) from where it guards the black King. (Authors)

Superb! Congratulations to the authors

Thanks Luce. It was really a very hard labour put in especially by Vlaicu.

Both Ks transported to their final squares alternately on the lines g2-a8 and g7-a7.
A total of 7 pieces thematically captured in each solution to reach the final position with only the Ks and a BB/BR.
Typical T&M sacrifices and teleportation all over the board.
Another fine addition to the joint work of the Indo-Romanian duo.

Very nice Superguard effects in the last two moves. I wonder if a6 can be white to add some more apparent choice to both.

• Vlaicu Crisan пишет:

Thanks for the suggestion. Unfortunately, with a wPa6 the solution in a) would not work any more because White can play 5.Kxb6→b5.

• seetharaman kalyan пишет:

Oh.. yes I missed that b5 needs guard !!

with a6 as wP, wK can escape in (a) with 5.K*b6-b5,b4.
