Nf3 6 gxf3 g2 7 f4 and Black mates with either g1=Q/R 8 f5 Kh7 (or Kh8)

and Q/Ra8#, or 7...g1=N 8 f5 ... 10 f7+ Kh7! and 12...Nb3(c4)#. 5 Kb4

f1=Q 6 b4 = but 1...g3! (for 2...f3) forces 2 Bxg3 fxg3 etc. as after 1 Bg1

1.Bg3! fxg3

Same position after 1 Bg1(e1/h4) g3 2 Bxe3(g3) fxB but with an extra

bPg4, which will help White. If instead 1...e2 2 Ka5!, and then 2...fxg3

transposes, while if Black advances the King instead of 2...fxg3 then 3 a4, 4

b4, 5 Be1, 6 g3 (threat gxf4) and Black can make no progress without

giving stalemate.

2 Ka5! e2 3.a4 e1=N! (e1=Q+ 4.b4 = as before) 4.b3!!

Mutual Zugzwang! not 4 b4 Nf3 5 gxf3 g2, and now if 6 fxg4 g1=N/Q/R

and mates in 3, while if 6 f4 g1=N still mates in 5 and even 6...g1=Q/R wins

(the extra bPg4 does block the route to a8, but 8 f6 Q/Rxa4+ and the g-pawn

Queens safely). nor 4 Kb4 Nxg2 and the extra Pg4 only gives Black more

winning options compared with the first-move tries.

4...K-any

After 4...Nf3(?) 5.b4! is again mutual Zugzwang, but White can also draw

with 5 Kb4, 6 a5 etc.

5.b4 (still not 5.Kb4 Nxg2 etc.) Nf3 5.gxf3 g2 6.fxg4 g1=Q/R/N 7.g5 =.

Wherever Black chose to move his King on move 4 he must now either

allow stalemate or waste a tempo getting out of the Pg5`s way, and then 10

g8=Q arrives in time to cover a8 or b3,c4 and Black has nothing better than

to capture the promoted pawn and stalemate anyway.
