White needs to do something or throw in the the towel.

1.Bxf4 any move but exf4?? (allows rook and queen sacs and stalemate.)
1....I`m trying to find blacks best move. Lot of options but with the white bishop
on f4 white will now have mating chances unless black plays 1...exf4 and allows the stalemate.

or
1.Bxf4 Bg5
2.Rg8+ KxR
3.Qg6+ and perpetual checks

The pawn on g4 can move, I can\'t see stalemate happening with sacrificing the rook and the queen as white has to play g5 whuch black then follows up with Qh3#-

Sorry ,Baggy you`re right, that g pawn ruins it.

6Canada  cc14226285672014-04-10 07:14:00
no it doesn\'t.I think your partly right.
1.Bxf4 exf4
2.Rg8+ Kxg8
3.Qg6+ Kf8
4.Qf5+ Kg8 or Kg7
5.Qg5+ Bxg5 is stalemate

and 4....Ke8 leads to perpetual check after 5.Qc8+

Not 1.Be1? Qxe1 2.Kh2 h3 3.Qc2 Qg3+ 4.Kh1 Qxf3+ 5.Kh2 Qg3+ 6.Kh1 Qe1+ 7.Kh2 f3, which is hopeless for White, while 1.Rg8+? Kxg8 2.Bxf4 gives Black the additional option 2...Kg7, which, in fact, wins.

1...exf4

In case of 4...Ke8 White gives perpetual check on the light squares - the opposite colour from Black\'s bishop. 5.Qc8+ Kf7 (5...Bd8 6.Qe6+ Kf8 7.Qf5+=) 6.Qf5+ Ke8 7.Qc8+ =.

After the text move, it looks as if White\'s defensive resources are exhausted. However, he has one final idea.

5.Qg5+!!
