| May-15-07 | | Marco65: Now I see that also the variation that I thought it could save the exchange it doesn't: 30.Rg1 g6 31.Bf4 Bxd5 32.Bxd5 Ra6 33.Bc4 and now:
a) 33...Rc6 34.Bb5 Rxc2+ 35.Qxc2 Qxb5

it might be worse actually...
b) 33...Ra8? 34.Bxd6

hopeless imo: 34...Bb6 35.Re1 Qc8 36.Bxf7+ Kxf7 37.Qd5+ Kf6 38.Qe5+ Kf7 39.Qe7+ Kg8 40.Qg7# |
|
| May-15-07 | | chessmoron: 30.Re1 posted.
I'm thinking 30...Bxd5 again. Any thoughts. |
|
| May-15-07 | | Marco65: Always surprises! Yes 30...Bxd5 seems playable |
|
| May-15-07 | | Marco65: Unfortunately 30...Rc8 is too slow: 31.Qd4 gxh6 32.Bxh6 Qe5 33.Rxe4  |
|
May-15-07
 | | TheAlchemist: Hmmm, I think they played a very good move. After 30...Bxd5 31.Bxd5 Rc7 32.Bb6 Re7 33.Bxf7! Qxf7 34.Bxd8 they end up a piece ahead:

|
| May-15-07 | | Marco65: I was wrong: 30...Rc8 31.Qd4 Qe5 32.Bf2 Qxd4 33.Bxd4 Bg5+ 34.Kb1 Bg6
click for larger viewAnd 30...Rc8 31.Bf4 a4 32.Bxa4 Qxa4 33.Rxe4 Ba5 seems playable, but this analysis is not exhaustive |
|
| May-15-07 | | Marco65: <What do we do here?> In your variation did you examine alternatives 31...Rc8 or 33...Kh7? Good night (1am) |
|
May-15-07
| | TheAlchemist: <Marco> 31...Rc8 32.Rf1 maybe? 33...Kxf7 34.Qd5+ Kf8 35.Rf1+ and we're dead |
|
May-15-07
| | TheAlchemist: There's a funny possibility in my diagram, namely 34...Qxa2, threatening mate. Does it work? It's late now, so anything I come up with will surely be flawed. See you tomorrow (or should I say later today :-)) |
|
| May-16-07 | | chessmoron: I have feeling that we are heading in an unbalanced position but IF we play well, I'm hoping we can hold. Hate, Hate for unbalanced endgames. Hold me. :| |
|
| May-16-07 | | Marco65: <34...Qxa2, threatening mate> 35.Qf2 keeps the extra piece for them |
|
May-16-07
| | TheAlchemist: <Marco> I came up with 35.Qf2 Rxe1+ 36.Qxe1 Qa1+ 37.Kd2 Qxe1 38.Kxe1 a4
click for larger viewCan we draw this? My endings are bad, so I can't tell for sure. But before embarking in anything like this, we have to be sure. |
|
| May-16-07 | | Marco65: <TheAlchemist> You're right 33...Kxf7 loses, but 30...Bxd5 31.Bxd5 Rc8 32.Rf1 Rc7 might hold imo, now 33.Bb6 Re7 is possible. The point is that if we want to move that rook to c8 we'd better do it immediately, 30...Rc8 has the advantage of threatening 31...a4 os it might be more forcing. White is now threatening Ba4, so our candidate moves are movements of Rc8, of Qe8 or intermediate moves like ...Bxd5 and ...Bh4 |
|
| May-16-07 | | Marco65: <TheAlchemist> While you were posting I analysed that endgame indipendently, and even not worrying about best moves for White I could only lose! I started with 39.Be7 a3 40.bxa3 bxa3 41.Bxd6 a2 42.Be5 and now tried both with gxh6 and g5. We are just hopeless |
|
| May-16-07 | | Marco65: An interesting line about my proposed <30...Rc8>: 31.Bf4 a4 32.Qxb4 (I was a little worried about that, question: can White just grab all our pawns and ignore the loss of the bishop since our one is pinned?) 32...axb3 33.Qxb3 Qe6
34.Nc3! Qxb3 35.Rxe4! Qxb2+ 36.Kxb2 Bf6 37.Re3
click for larger view
Answer: yes they can, but we are by no means worse |
|
| May-16-07 | | Marco65: Yet another variation <30...Rc8> 31.Bb6 a4 32.Bxd8 axb3 33.axb3 Rxd8 [33...Nxd8? 34.Qg5! Ne6 35.Nf6+ Kf8 36.hxg7+ ] 34.Qd4 Qe5 35.Rxe4 Qxd4 36.Rxd4 Nxh6 37.Rxb4
click for larger view
with a double-edged endgame. Again we are still in the game |
|
| May-16-07 | | Elixir of Life: I would vote for <30...Rc8>. I don't have much time to analyse now, but I would say that after <30...Rc8> and <31...a5>, we could perhaps put the rook on the b-file to support the b pawn, that might be beneficial. It might also stop the white rook from taking the b-file, as it has in <Marco65>'s last posts final position. But maybe not. |
|
| May-16-07 | | Marco65: Just to point out a mistake of mine:
<30...Rc8> 31.Bf4 a4 32.Bxa4 Qxa4 33.Rxe4
click for larger view
and here I suggested 33...Ba5 but of course that would allow 34.Ne7+ We lose b4 here, and I'm afraid this refutes the whole 30...Rc8 idea, or at least makes it much more attractive. But what then?? |
|
| May-16-07 | | Marco65: <Elixir of Life> Thanks for your vote, unfortunately 30...Rc8 + 31...a4 doesn't seem to work to me any more, but maybe you can find a flaw in what I posted. |
|
| May-16-07 | | chessmoron: <Marco65> 30..Rc8/30...Bxd5 all leads to the dreadful 31.Bf4. Anyone seeing 30...Bh4? |
|
| May-16-07 | | Marco65: <chessmoron> I tried but what after 30...Bh4 31.Bf2 ? It seems our bishop will stay pinned forever (until captured) |
|
| May-16-07 | | chessmoron: <Marco65> 31...a5? So we can sac our rook for their queen after we lose our queen first. |
|
| May-16-07 | | Marco65: <chessmoron> I don't get it. Do you mean 31...a4? and after 32.Bxa4? |
|
| May-16-07 | | chessmoron: *sigh* guess you are right. I propose resign the game. Everything we move, loses. |
|
| May-16-07 | | Marco65: Also 30...Qf8, usually passive but safe, fails here: 31.Bf4 Bxd5 (otherwise 32.Ba4) 32.Bxd5 Ra6 33.fxg7 Kxg7 34.Rg1+ Kf6 and I don't need analysis to refuse to enter this |
