Re8+
1 Re8+ Rxe8
2 Re8+ Rxe8
3 f7+ b2
4 f8 = Q #
Well, 4 fxe8 is correct. Forgot about the rook…
4… g7
5 Bxb2 + and so on
Gegga
f7
1. Re8+ Rxe8
Black is forced to recapture
2. Re8+ Rxe8
Again, black is forced to recapture
3. f7+
Exposed check from Bishop on a1
Black’s King can not move,
the pawn on f7 guards g8.
Black must interpose
If
3. .. Re5
4. f8=Q#
3. .. Ne5
4. Bxe5+ Rxe5
Again, black is forced to recapture
5. f8=Q#
Not that it affects the outcome, but Black would probably play:
3…b2
… not 3…Re5 or 3…Ne5.
I guess 1.f7 is winning as well, the first move noticed is of course not the forced variation 🙂
1. f7 loses to 1. .. Rf8
to Anon 6:56
sorry, you are mistaken…
1.f7 Rf8?
2.Rc5+ Ne5
3.BxN++
“sorry, you are mistaken…
1.f7 Rf8?
2.Rc5+ Ne5
3.BxN++”
2. Rc5+, b2!? or even better Rxa1!
Why should he play Ne5!?
1. f7 only wins if black makes a mistake like 1. -, Rxa1 (which looks good on first glance) 2. Re8+! 1:0
Rf8 is a good defense, perhaps 1. -, Kg7!? (or ??) is a curios second one…
Ah, nope, 1. f7, Kg7 gets ?? because of 2. Re8+, Kxf7 3. Re7#.
So 1. f7 Rf8! seems to be the only defense. But one defense is enough, isn’t it!?
On
3. .. b2
4. Bxb2+ Nxb2 (or other interposition already covered)
5. fxe8=Q# Kb7
6. Qe5+
(forking the knight and king, leaving White with a won Queen vs Bishop game)
