bxd5 pxb qxd5+ be6 qxn then after this not sure looks winning maybe black would try trade queens with qb8 (also protects b2) then i think rxf5 bxr qxb and rook h7 is lost so black have to play ra7xb pxr+ kxp qd7+ k h8 or kh6 and rxb7 and black is lost

Good day,

Let's see, I do not think that 1 Bxd5 is really the move...

Let's see if 1 Bxd5 then: black has no need to take the bishop with the pawn as frank suggests 1... Bc6 should be secure for black and with equal pawns it should be quite drawish, since white bishop is pinned due to queen being uncovered behind it.

Thus, if 1 Bxd5 black would play 1... Bc6!! 2 Rxf5 QxBd5 covering knight, 3 QxQd5 BxQd5 4 RxNe5 with slight advantage for white but not enough I believe.

[FEN "3q2r1/pp1b1kBr/4pP2/3pnp1p/8/1BP5/P2Q2PP/1R3RK1 w - - 0 0"]
1. Bxd5 Bc6 2. Rxf5 Qxd5 3. Qxd5 Bxd5 4. Rxe5 Rc8 1/2-1/2

I was thinking on something about 1 Rf1xf5 to try and get the knight or going for mate.

Like this: 1 Rxf5 if 1... e6xRf5 then:

[FEN "3q2r1/pp1b1kBr/4pP2/3pnp1p/8/1BP5/P2Q2PP/1R3RK1 w - - 0 0"]1. Rxf5 exf5 2. Bxd5+
Be6 3. Rxb7+ Kg6 4. h4 Nf7 (4... Qxd5 5. Qg5# ) 5. Bxe6 Rhxg7 (5... Qxd2 6. Bxf7# ) (5...
Rgxg7 6. Bxf7+ Kxf6 7. Qxd8+
Ke5 8. Qd4# ) 6. Qxd8 Nxd8 (6... Rxd8 7. fxg7 Nh6 8. Rxa7 Kf6 9. Bb3 Rc8 10. a4 f4 11. a5 Rxc3 12. g8=Q Nxg8 13. Bxg8 ) 7. Rxg7+ Rxg7 8. fxg7 Kxg7 9. Bxf5 1-0

Or if 1... Qb6+ making white defend for a bit first:

[FEN "3q2r1/pp1b1kBr/4pP2/3pnp1p/8/1BP5/P2Q2PP/1R3RK1 w - - 0 0"]1. Rxf5 Qb6+ 2. Kh1 Ng4 {now white needs to defend for black's knight + queen attack, thus queen cannot go to attack nor can rook go.} 3. Bc2 Qe3 4. Rxd5 {Look that if exRd5 then Qxd5+ if Be6 then Rxb7+ Ke8 Re7# and if Qe6 then QxQe6 BxQ Rxb7+ and then BxRh7!! and white wins.} Qxd2 5. Rxd2 Rhxg7 6. fxg7 Bc6 0-1

In both cases white should win although in these last case it will be quite difficult.

good day,

perhaps this line give the best change to win...1. rxf5 rhxg7 2. fxg7+ exf5 3. Qxd5+ Kg6 4. Qxg8 Qxg8 5. Bxg8 Kxg7 and white has a clear advantage in the endgame, because of its rook on b1....

Thanks to All....
