white Pe5 Kg6 Bh5 black Pd6 Ke8 Ra8

h#1,5 King in disguise(3+3)

Solution

{

} 1...Kg6-f7 {
pe5 cannot be a disguised King and as the White King cannot checkmate, it is therefore Bh5 which is the disguised White King} 2.0-0-0 {If Ke8 had been a King, it could not have castled as it was in check at the start of the move, so it is the Black Rook which is a King in disguise, hence the mate : } Kf7-e8 #

white Kh8 black Pg7f7 Bh5h6

h#2 King in disguise(1+4)

Solution

{

In the diagram, both f7 and g7 cannot be kings in disguise because the white king must have passed through the 8th row to reach h8
} 1.g7-g5 Kh8-h7 2.g5-g4 {
now we realise that Bh5 is the Black King in disguise
} Kh7*h6 #

white Pc2 Ke1 Rh1 Bb1 black Ph2 Sh7 Bg8g5 Ra3

h#2 King in disguise(4+5)

Solution

{

} 1.Bg5-d2 {the Bishop is therefore not the Black King in disguise
} 0-0 {that the rook is not the white king in disguise,
because it could not have passed through g1.
The last white move before the diagram position was therefore Ba2-b1, with or without a capture.
If he is king in disguise, the preceding black move was necessarily Rb3-a3 +
which prohibits the black rook from being king in disguise likewise for the Bg8,
it's the Nh7 that does it !
} 2.Bd2-g5 {switchblack capturing the escape square g5 at Nh7
} c2-c3 # {so Bb1 is the King !}
