Move 36
 
Only 36...Bc5+ and 36...Bxe7 avoid losing a piece and being a rook down as far as I can see.

And 36...Bc5+, suggested by Paul last move, is definitely my choice now. As he pointed out, they must either put their king in the corner (a backward move for the ending) or block their bishop's retreat to f1.

Without the check by us we could play:

35...Bb4
36.Nxe7 Bxe7
37.Ra7 Nb3
38.Bg4 Ke8
39.Ra6 Bb4
40.Rxg6 Bd2

as I pointed out before, but I am happy to go with the majority vote. :smile:

The refutation of 37...Nb3, as given in the last thread in response to your posting, was the line 38.[B]Bf1[/B] Kf6 39.Ra6+ Kg5 40.Bc4. It was this key move of theirs, Bf1, which we can hope to negate by playing 36...Bc5+, hoping that they might forget what cheesehead probably told them and play the weak reply 37.Kg2,

paulunderwood 2014-07-13 13:53

Ah I see now! :blush:

Well, shall we agree on Bc5+ and go ahead and play it?

richs 2014-07-13 23:58

I agree with Bc5+ but no need to rush. Give them more time to forget. I can't believe that the three remaining members of their team consulted and agreed on a move in 6 hours.

I am not sure I see the negatives to this position. If he tries 40.Ra7 we just do Kf6. He would need to do something different if he wanted to avoid three-fold repetition.
If he does 40.Bc4 then we do Nd2.

Oh yes, this looks possibly good. After 40.Bc4 Nd2 41,Bd3 I thought we would have the unpleasant choice of giving up either our a pawn or [I]both[/I] our kingside pawns, but now I see 41...Nf3+ 42.Kf2 Ne5. If this does indeed work, then we should [I]not[/I] play 36...Bc5+: the line only works if their king starts on g1.

Can anyone else see anything wrong with this line?

By the way, Rich, I am only aware of 2 remaining opponents, LaurV and WMHalsdorf, now that both bsquared and cheesehead have left. No-one else joined them, did they?

38.Bg4 looks bad for us?

You looked at this line yourself in the last thread:
[QUOTE=paulunderwood;377569]On second thoughts, we might move like this:

35...Bb4
36.Nxe7 Bxe7
37.Ra7 Nc3
38.Bg4 Ke8
39.Ra6 Bb4
40.Rxg6 Bd2

Looks okay -- sorry if this is not a new line :unsure:[/QUOTE]
(assuming you meant 37...Nb3).
I responded that I thought 38.Bf1 refuted this line. Now, after David's correction, I'm not so sure it does.
Do you still think your line above is okay for us, Paul (and others)?

paulunderwood 2014-07-15 17:34

I think that line is best for us, other than other lines with a knight sacrifice and moving all play to the Kings' side :unsure:

Brian-E 2014-07-15 17:49

Are the lines with knight sacrifice and moving play to kingside worth considering in your opinion? If so, what lines do you mean, specifically?
