To Lambent …
1.Qd8 QxQ
2.Ra8 Rd1
3.Rc8.
White isn’t the one with the back-rank problem here.
To anon 2:17:00
1.Qd8 QxQ
2.Ra8 Rd1
3.Rc8 then Black has
3….Kh7
1. Qd8+ Qxd8
2. Ra8 Rd1
3. Rc8 Kh7
4. b8/Q wins as
the Qd8 still cannot move and
4… Rxf1+
5. Kxf1 Qd1+
6. Kg2 leaves white in a winning position.
alternatively
4… Rg8
5. Rxd8 Rgxd8
6. Qb6 also wins.
To anon 4:54:00
”5.Kxf1 Qd1+”
much better is 5…Qd3+
1. Qd8+ Qxd8
2. Ra8 Rd1
3. Rc8 Kh7
4. b8/Q Rxf1+
5. Kxf1 Qd3+
6.Kg1 g5
7.h5 Kh6
8.Rh8+ Rh7
9.Qf8+ Kxh5
10.Qxf7+ Kh6
11.Qxe6+ Qg6
12.Rxh7 Kxh7
13.Qxg4 white has winning advantage.
1. Qxf7+
To tadman:
1. Qxf7+, Kxf7
2. b8=Q is no longer check and black can take your knight and probably mate before you can do anything.
What about:
1. b8=Q+ right away?
Actually I guess
1. b8=Q+ doesn’t work either, after the king moves away White can’t do anything quick enough to stop:
2. …Qxf1+
3. Kh2, Qh3#
To Sergey:
Look again; if 1… KxQ
2. b8(Q)+ [discovered]
” tadman said…
1. Qxf7+”
!.Qxf7 Rxf7
2.b8Q+ Rf8 and Black wins.
