|Jan-24-17|| ||centralfiles: another pun!|
|Jan-24-17|| ||centralfiles: btw do you have an opinion offahnd about that position in the last diagram would be nice to hear it...|
|Jan-31-17|| ||FSR: <centralfiles> Sorry. I will definitely take a look at it.|
|Jan-31-17|| ||centralfiles: Thanks|
|Feb-04-17|| ||FSR: <centralfiles> I'm not sure if White can make progress after something like 26.Kd2 Bd7 27.Bd4+ Kh6 28.a5 a6 followed by ...Bc6, then shuffling the rook around.|
|Feb-06-17|| ||centralfiles: Hmmm....
I was worried about something lke that.
But i wasn't sure about Black being able to prevent a white king penetration perhaps in tandem with a rook lift if possible when blacks Bishop is tied down defensively and whites bishop is just where its wanted.
I guess its unlikely white has forced win perhaps some chances at best.
Thanks for the input I think in these endgames your precursary look is at least as good as my long analysis...
|Feb-06-17|| ||centralfiles: In your line
followed by Bb6 and Rd6/d8

Though White will probaly have to be prepared to give up a or c pawn to retain chances.
|Feb-06-17|| ||moronovich: Hmm,in the diagram above it looks like white could go Be5,Rd6 marching the king to b6 and sacking an exchange and go Kxa6 winning,takes 6-7 moves.At least it is a major threat.|
|Feb-06-17|| ||centralfiles: <moron> keep in mind it's Blacks turn.
But that could be a possibility.|
|Feb-07-17|| ||moronovich: <centralfiles> You can use the idea above to find blacks move.So perhaps-Re8 is forced,to prevent the Be5,Rd6 plan.And btw my handle is moronovich and not moron,but you perhaps meant it in a humorous way !?|
|Feb-07-17|| ||centralfiles: Sorry about that <ovich> I was actually just shortening it without thinking about how it came out...
Though I do remember you calling yourself <moron> in chessbookie's forum some time back.
BTW if It's a real name I would change the spelling ;)
Muranovich is just fine.
I hope not to do that again to you or anyone else.
|Feb-07-17|| ||centralfiles: <You can use the idea above to find blacks move.So perhaps-Re8 is forced,to prevent the Be5,Rd6 plan>|
I dont think 30...Re8 is forced though it is a good option.
Black can try 30...Rc8 eying c-pawn.
30...Rf8 and now Be5 is met with ...Rf5.
30...Bb5 or ...Ba4 with ...Rc8 possibilty.
30...Kg5 when Be5 will simply be chased around with ...Kf5.
The exchange sac might be possible if black allows it but Black has many active ways not to.
I was hoping to infiltrate with the Rook, But Black will be able to play against weak a- and c-pawns. So only way forward is to create unbalanced position where black might win back pawn but white has aggressive ideas.
This is exactly what I would never be able to do successfully OTB. Leave it to me to somehow lose if i got here...
|Feb-08-17|| ||moronovich: Hi <centralfiles> !|
Sorry for beeing a little late..
It is really a tricky an interesting position with more content than meets the eye at first sight IMHO.I can understand if/when you feel dragged to it
On 30-Rc8 I would answer Be5 and if 31-Ba4 then Rd6 with the idea 32-Rc5 33.Kf4 ! were white is clearly better,as far as i can see(E.g with the threat of mating with Rd8-h8#).But I may be overlooking something..
IŽll return to Re8,Rf8 in the days to follow.
|Feb-08-17|| ||moronovich: <So only way forward is to create unbalanced position where black might win back pawn but white has aggressive ideas>|
I guess you are spot on here.Play against the weak black king may be the only way to win with white.
|Feb-08-17|| ||centralfiles: What about
The bishop seems misplaced a bit on a4.
BTW I try to use engine to help me analyze but even stockfish is clueless here. It doesn't know how to make progress and will often just shuffle while evaluating +1.0 to 1.4 throughout.
It's good for trying out ideas when you can quickly see if your making progress and what blacks ideas are.
I don't really get how it even knows what to evaluate since it can't make progress but I guess it has some kind of algorithm that can sense chances.
|Feb-09-17|| ||moronovich: If 31.-Bb5.32 Rd6 with the idea of going Bf6(blocking your vital f-file and threatening g4-5+,which looks scary or outright winning ?|
But 31..Re8.32.Bf6-Re6(if Rf8,then Rd6)then 33.Bd8(!) controlling the vital f6 square and still playing with the presumeably strong g4-g5+
This suggests that 31...Rf8 is the best,playing trying to prevent the g4-g5 threat,due to the weakening of the f3-square.Let us say 32.Bc7(dont fancy the f4 check at the moment)Rf7,Bd8(!?)
Rd7,Rd4(!)were I am not shure black can allow RxR-c(!)xR,threatening Kf4 winning I think.
But it is a thriller.And I agree with SFŽs range of 1.00-1.40 which may be telling that white has as good winning chances as black has drawing ch do.
I am still working on it.Many other options.
|Feb-09-17|| ||centralfiles: In the 31...Bb5 abd 31...Re8 lines the strength og g4-g5+ is not so apparent assuming white can get a few moves in fore free after
31...Re8 Bf6 Re6 Bd8
What would they be that would show your point?
in the 31...Rf8 line I never wouldve realized allowing rook exchange was possible but it seems d-pawn is much better than the blocked c-pawn.
It takes the fish awhile to agree with you.
35...g5 preventing Kf4 is getting 1.13 eval(very high for a no rook position)
on any other position eval jumpt least 1.6
|Feb-09-17|| ||moronovich: <What would they be that would show your point?> Still playing with the brute Rd8-Rh8 mating or threatening mate(after Kh5, with a white pawn on h3)And,or caving the way for the white king to enter f4,trying to take profit from the element(s) of zugschwang in the black camp.But I dont know if it is winning.Or when/if g4/g5 is premature..And in some lines the bish goes to f6(with white pawn on g5),killing all black play via the f-ile).These were the thoughts behind the g-pawn push. |
<in the 31...Rf8 line I never wouldve realized allowing rook exchange was possible but it seems d-pawn is much better than the blocked c-pawn. It takes the fish awhile to agree with you>
Well it also took me a while ...I think it came after a little daily shopping at the local store with all the pawns and pieces in my old head.Suddenly it dawned on me.Which reminds me of way back in 1985 where I asked Larsen if he would look at a position I had in CC-game.He accepted
and after being a little starstruck the first few minutes, we,much to my delight were equals in about one hour.But then he showed pure genius :"Out of the blue , he took the black bishop on g7(it was a closed sicilian)went,Bg7-f6-g5-e3+ and I was positionally busted!! IŽll never forget this lesson.
And I hope you will continue to dick deep in this interesting position.And who knows:perhaps we can reach a conclusion !?
p.s. I have no chess-engine in the house.
|Feb-09-17|| ||moronovich: And one more point in the g5-Bf6 constellation is that in some lines, white has the possibilty to go Rd1-g1-g3/g4 with almost mate ;).|
|Feb-09-17|| ||centralfiles: hmmm....
I think the only way to reach a conclusion will be to first establish several goal positions that can be shown to be winning or drawn and then work backwards otherwise I for one will be in indefinitely lost in all the variations.
|Feb-12-17|| ||moronovich: I have been through many tries,but so far black seems to hold.But OTB IŽlll give white around 20-25% if he is up to the task.|
Whites best set up,so far is with Rd6_Bf6,but black can prevent this with 30-Rf8 which is better than Rc/e8.It is critical to go Rf5-d5 or Rf7-d7 in the mainlines IMHO.We also saw that black should not allow -Rxd4-(c!)xd4 and with a setup as mentioned with Bf6,Rd6,pawn g5,black can usually not take on c3/a5.
So IŽll give it a rest,but just say I am open, if you want to take it further.Despite(and because of!;)the hard work, I have enjoyed the ride.
|Feb-12-17|| ||moronovich: And thanks to <FSR> for hosting !|
|Feb-12-17|| ||centralfiles: I actually was coming around to similar conclusion that ...Rf8 and Rf5 will be the hardest but to crack but I was still holding out on finding some idea.
Also an important note I think you only started analysis from my last posted diagaram after 31. Rd1.
But this was working with FSRs suggestion of 27...Kh6
On 27...Kf7 It's a different position with other ideas for white.
But what about 27...Kh7 then 31.Rd1 can perhaps be met by Rd8 and deny whites rook entry at all.|
On a different note FSR very likely did not have check his profile in awhile and might be sirprised too find himself hosting.(does that make a kind of parasite?)
|Feb-12-17|| ||moronovich: .<(does that make a kind of parasite?)>|
I guess he welcomes it.
