1 - h#6 3 sol maximum white with sparrows
Kotesovec, V.2020
white Ka1 WSc1
black Ke2 BSa5b2
h#6 maximum white 3sol.(2+3)
🨊c1 🨐a5, b2: Sparrows
: White is required to play geometrically longest legal moves
: Sparrow is a 135-degree or -45-degree Grasshopper.
In short, the pawn on c1 can, using the b2 jump, move to c2 (a3-b2-c2 = 135 degrees or c1-b2-c2 = 45 degrees) or to b1 (a3-b2-b1 = 135 degrees)..
An easier way: Play a Grasshopper move, then move back one Knight's move!

The White Sparrow attacks the Black King with the jump b1 and controls the d1 square with the jump e2.
Note that if the Sb1 moves to b2, the RN remains in check, as the jump has now become b2.}

2 - h#2 3 sol back-to-back
Vilkauskas, A.2020
white Pg5 Kd2
black Kd5 Be6e5 Sf6 Qh8
h#2 back-to-back 3sol.(2+5)
: if two pieces of opposite colours are ‘back-to-back’, for example a white piece on e5 and a black piece on e4,
They swap their moving way.

He is now playing as a bishop and delivering check.} 2.Kd5-d4 e6-d5 # {
He now plays like a King.
And black King, playing like a pawn, cannot capture it.}

3 - h#3 with set play PWC einstein kobul kings
Stun, J.2020
white Pf3
black Rg4 Kh1
h#3 set play(1+2)
PWCEinsteinKobul Kings
: The move is given to the player who would normally play second; here, the specification becomes h#2.5
: The captured unit reappears where the capturing unit was located at the start of the capturing move.
: a unit (other than the King) changes on every move to the next strongest unit in the event of a capture,
immediately less if no capture.
: When a piece is captured, the King of the piece's side gets its moving way.
He becomes a normal king again if a pawn is captured.

4 - serial h=7 make & take
Caillaud, M.2019
white Kf4
black Pb6f2g2 Ka5
ser-h=7(1+4)
: The capturing unit first moves as the unit it wishes to capture,
then perform this capture while moving normally.
In the first phase, a capture is not allowed.

Note that } 1.g2-g1=Q + {check via h2}
1.g2-g1=R {(and here} 2.f2-f1=B + {check by Rg1 via f2)}

Black can’t even twitch an ear!
Each move frees up a square, allowing the Black King to be captured.}
