Hmm, I think you may need to ask directly to Leela programmers.

...and today she got nicely defeated again:

 

drmrboss

 Leela must play 25... Rb5!!

Passed pawns must be blocked(must be pushed from those having  passed pawns)

 
 
 
 

 

drmrboss

According to my knowledge, defender rook on 5th rank is draw! 6th rank is lose. 

This is draw!!

 

 
 
This is Forced lose! 1-0

Interesting! I Never heard about this "5th vs. 6th rank" rule...

For some reason, I think that 29...Ke5 still held - but I may be wrong of course.

drmrboss

5th rank is the minimum  required rank to get a draw.If your rook can block in 3rd and 4th rank, it will be much easier to get a draw. It would be good to check carefully  with stockfish!( i am bored to check though)

Leela Zero  perfectly found Scott opening by her own up to 5. Be3.  5. ---Ne5 was bad move according to SF .  . 3500+ rated Daddy Fish will immediately punish for such inaccuracy!!

That is quite a game! Underpromoting to a rook did look a bit like taking the ####!

Dammed Leela is cursed as 2000 whereas A0 was cursed at 3300.(looks like Leela need larger network)

That is a respectable human rating, and Leela has to get credit for that as well as being rather human-like in her play.

I got the cpu version (1 thread) of LCZero (ID 69) installed in Arena; No problems at all. It's currently battling Roce 0.0360, and it's roughly 20 points ahead after 90-something games. Roce 0.0360 is rated around 1670-ish, so LCZero cpu is playing at about a 1690-ish level, more or less.

It's getting stronger very quickly. Tonight I lost for the 1st time.

The finishing touch (the last few moves) already shows the strong ability of a master. This is scary!

Of course I'm playing quickly and rather casually - but just a week ago this was all so easy!

Some rating list showed that Leela reached 2274 in Geforce GTX 1060 at 1 min/ game time control.  On play.lczero.org , I dont know her rating, but some people guess 1500-1600 on instant move and 1800-1900 on longer time. Those all estimates,but she gained about 250 elo from last week.

In your game i dont like 11.e4!? centre break strategy . May be 11. h3, (to save bishop when black attempt to exchange with kt), prevent black from pushing e5. And then b4, Qb3, b5 queen-side push.

This is scary, an AI learning online by playing against humans, imagine when it hits 2800, can’t be more than a few months away when it can increase its strength by 250 rating point within a week.
solskytz

<drmrboss> definitely a good tip on both counts!

I did consider the Q-side strategy you mentioned, but finally went for 11. e4.
