Re: Can it be Saved?

Here's a short line. 1. Rb6 Rxa5 2. Rb3 Be6 3. Rc3 Rb5+ 4. Ka1 Rxc3 5. Rc7+ ( Kxc7=) Kd8 6. Rxc3= :) That might work too, the problem is, no engine would play 2... Be6 seeing the following leading to immediat exchange of rooks with at least complete 5 MOB on disk or in main memory. :) After I manag...

Re: Can it be Saved?

Will play out starting from Rh8+ with 90+30 time control. Do so! But if I may give advice, don't trust any engine with too much nullmove- pruning here, Terry McCracken was right about zugzwang. No Rybka, no Robbka will help in such positions. Don't know if Crafty has switched off nullmove pruning w...

Re: Can it be Saved?

Rh8+ seems to be the better move, but whether it leads to draw, no way to tell. So than just one more for the other side. :) 2k5/3b2R1/7R/P3r3/2r5/8/1K6/8 w - - 0 1 1. Rh8+ Kc7 2. Kb3 Rc1 3.

Re: Can it be Saved?

Rg8+ is not the best move as it immediately gives more power to an already empowered Bishop while leaving the white King exposed to the attacking Rooks. So you're in doubt yourself again? :) 1.Kb3 you've already tried, 1.Kg8 was Eelco's favorite too, if I remember right, considering 1.Kh8 too? If s...

Re: Can it be Saved?

I think this postion should be a draw but it's no mean feat to avoid all the potential zugzwangs if White fouls up. It's an easy draw like Lawerence said earlier if you reduce it to K+R to K+R+B. GM's have had difficulty in such endings but it should be a technical draw even with all material on th...

Re: Can it be Saved?

At first glance, one immediately leans toward draw, but as you begin to analyze, it gets more interesting. I think a 7-piece table is probably the only solution. Or if anyone is interested, we could play this position out. You use whatever resources are at your disposal. It would be fun. I guess it...

Re: Can it be Saved?

At this point, it may be that the position is lost, but not conclusive unless tested with 7-piece EGTB. Here is the results with time control increased to 90m+30s increments with hash of 1024 MB using 4 cores with ponder off. [d] 2k5/3b2R1/7R/P3r3/2r5/8/1K6/8 w - - 0 69 69. Kb3 {(1.Kb3 Rf4 2.Rh8+ K...

Re: Deep Junior 2010

Sorry, but you didn´t buy Deep Junior 2010, but Bobby Junior 2010. You will have Deep Junior when it is released by Amir, and you dont will pay nothing for it. I think you are misunderstanding something. Bobby Junior is the GUI. Junior is the engine. There are two combinations: Bobby Junior + Junio...
