+/-
the basic idea is to involve ba3 into the attack via b4-b5
1. qd6 ke8 (bd7 2. qf8#; rd7 2. qb8+ ke7 3. b5 +-) 2. bg6 rf7 3. b5 qxg3+ i cant really calculate this but i do believe black has a perpetual because of ke2 bxb5+ threat
same with 1. qf6+ rf7 2. qd6 ke8 3. bg6+ (=?)
the most interesting is 1. qh8+!?
1… ke7 b5 +-
1… be8 2. qd6+ rd7 3. qb8 ke7 4. b5+ kf7
5. bg6 kxg6 6. qe8 rf7 7. qe6+ kg7 7. qxg4+ kh7 i dont see anything better than a perpetual
5. be6 kxe6 6. qxe8+ kf6 7. qe5+ and white gets an advantage in queen endgame after kf7 8. qf5 kg8 9. qd7 qg3 10. kxe4 qxa3 11. qg4+ kf6 12. ba ba whether white wins this I dunno, but they have a good chance
7. qxd7 doesnt’ really work 7… df3 8. kxe4?? qd1 -+ (8. ke2 qa3 9. ba ba — i cant really eveluate it)
axel
White wins starting with a check on f6.
1.Qf6+ Re7
2.Qf8+ Re8
3.Qd6+
If 2…Qc7, then
3.Qxe7+ and so forth
I can only see a draw for white.
ex:
1.Qd6+ Ke8
(1…Bd7 2.Qf6+ Kc8 3.Qf8# or 1…Rd7 2.Qb8+ Ke7 3.b5+ Kf6 [3…kf7 4. Qf8#] 4.Qe5+ kf7 5.Be6+ Ke8 6.Qh8#)
2. Bg6+ Rf7
Now I couldn’t fine anything better for white but 3.b5.
I tried [3.Qe6+ Kd8 4. BxR but black seems to draw by giving check with his queen. The idea behind 3.b5 is that this move’s threatening mate, and attacking the bishop and the rook where white cannot move his king at all, leaving him the only option to try to go for a perpetual.
ex:
3. b5 Qf3+ 4. Ke4 Qd3+ 5.Ke5 Qc3+ 6.Ke6+ Qc4+ and that leads to a draw)
There is a pretty line where black could go wrong that I found by chance!
3. b5 Qf3+
4.Ke4 Qd1+??
5.Ke5! Qh1+
6.Qe4! QxQ+
7.KxQ and white wins since king can march toward e6 and grab the rook for free( notice that black can’t move. And if black tries to march the e pawn for a queen white has enough time to play Bc1)
Of course if both side play correctly this is a draw.

your line is erroneous.
1.Qf6+ Re7
2.Qf8+ Be8!
and then what?
1 Qh8+ leads to a quick mate!
1 … Be8
2 Qf6+ Re7
3 Qd6+ Rd7
4 Qxd7#
or
1 .. Ke7
2 b5+ Kf7
3 Qf8#
To Cris falter.
White does not have a mate with Qh8+
your line gives:
1 … Be8
2 Qf6+ Re7
3 Qd6+ Rd7
4 Qxd7#?? BXQ!
Remember that you moves your bishop to e8!
If only white didn’t have the pawn on b4 there would be this win:
1. Be7+ Rxe7
2. Qb8 mate
or
1. … Ke8
2. Bg6 mate
there is a mistake in my line
1. qh8+ be8 2. qf6+ re7 3. qd6+ …. (second move missing)
still, i dont see a forced win but white can achieve a queen endgame where they are a pawn up and they have a good chance
axel
Qh8 Ke7 b5 seems to win. If black plays Be8, it looks easy unless i am missing something. 1. Qh8 Be8, 2.Qf6 Re7,3. Qd6 Rd7, 4.Qb8 Ke7,5. b5+
What is up with always doing this word verification? What’s the point?
