it is well checkmate because } 3.Ka1*h8 {via g7 would be followed by} Kh6*h8 ! {via g7 or h7
One might think that } 2...Qb8-e5 + {checkmate but there are 2 ways to avoid this : } 3.Sa3*e5 {via d3 or f3 and} 3.Ka1*e5
{via d4}
1.b2-b1=R {Note that Queen promotion would check via c1}
b7-b8=B ! {It should also be noted that the Queen promotion checking via a7 or a8 could only be parried by Kxb8 via a7 or a8,
the Rook not being able to interpose on the a-file}
2.Rb1-b2 Bb8*b2 # {via h8 !
Note that White King could not be elsewhere than in h6, under risk of insolubilities or demolitions.
As in Forsberg's famous (and brilliant) Helpmate 2#.
The White King could not be on g6 because on 2...Qh8+ would follow 3.Kb1 (no Qh7xb1) nor on f7 (3.Ka2). AUW}

an Argentinian unit plays "normally" when it captures,
but needs a sautoir to play a move that is not a capture, reversing the conditions of Chinese chess.
The Saltador plays like a creeping knight, except that it cannot capture if the two intermediate squares are occupied
and that he cannot play a no-take if the two intermediate squares are empty.
