{Comments: 
A long-term foresight proves why White needs to sacrifice the pawn 3.f3!! 
otherwise the black King would march to g2 and would capture the pawn from the 
right side (see lines I. and II.). Without the f-pawn, the magnetic rooks need 
to choose from two thematic checks repeatedly. The King cannot hide on either 
the h-file (where he has to accept the exchange of rooks), or the b-file (where he gets under perpetual check).}

Comments: 
Two main lines with different White's strategies. In one of them White draws 
by reaching a stalemate, in the other one by positional draw.
Eight thematic tries, distributed equally between both main lines.}

{Comments: 
At the very beginning, in the first thematic position, a quiet sacrifice is 
wrong while the checking one is correct. 
Later, in the second thematic position, a checking queen sacrifice is wrong: 
after 6.Qh8+? Black prevents to exchange the bishops 12...Bg1! and draws by 
nailing the wK to h4. 
On the contrary, the quiet queen sacrifice is then correct: 6.Qb8!! transfers 
the bB to b8 from where after 11.b6! it has no access to a7-g1, so Black is 
forced to exchange the bishops and White finally wins by the last pawn.}
