All the hash signatures including the pawn evaluation signatures are correctly being maintained. The pawn hash table and the main hash table have not been created yet. Nor has null move been implemented. They will be added soon! The node rate has taken a hit but it is still above 9 million nodes per second on a 3950x at 4.2 GHz.

[Mike Sherwin]

I have not done much except tuning what I had so far. Well, I did normalize the range for each piece type which seemed to help. After I started the current match I had to leave for a couple of hours. When I got back I was expecting the usual -131 give or take. Only 23 games have been played so far but also this is the first time with the new eval Bric has been even with TSCP, Bricabrac - Tscp181 : 11.5/23 10-10-3 (11000=001=1001110100=11) 50% ±0 ! I'll show the longest win by Bric and the shortest.

The score is now Bric +11 -10 =4. Maybe Bric all original will win its first match against TSCP!

[Mike Sherwin]

Well, Bric did not win that match. It was a new best but it did not win, -100 iirc. Then and for the next couple of days I was under the weather with an ear infection. Today was the next attempt. And a new best.

Bricabrac - Tscp181 : 42.0/100 39-55-6 (0010010010=00100011010=010001000=001=110101010011101010001110100011000000100101=100111111010=0000101) 42% -56

My initial goal is to rival or at least get close to PeSTO in the strength of just the PST. That is why I have not added end-leaf pawn structure evaluation. Adding end-leaf pawn structure would instantly make Bric much stronger than TSCP. Most games Bric is losing is due to disastrous pawn structure. PeSTO also suffers from poor pawn structure but not nearly as much. I wonder how the PeSTO pawn tables substantially avoids bad pawn structure most of the time?

One of my many disabilities is fibromyalgia. I suffered for years with it until I figured out the cause. Turns out that I have a mild allergy to Coffee. Because I love coffee. When I stopped drinking coffee my fibromyalgia symptoms diminished 99% in about a months time. After that an occasional mild flare-up but nothing serious. And I barely noticed it when it did. On May 7th I got the first Moderna vaccination. The first day or two I did not have any symptoms except a hint of a headache. After that I got what felt like an ear infection that sidelined me for a few days. I thought it was getting a bit better so I tried to do a little work on Bricabrac. But, while it did not seem as bad I noticed it was also starting in my other ear. Then I suspected that it might be a fibromyalgia attack. So I started pressing my finger on the various nerve bundles that are on the head and or face and sure enough it was a fibromyalgia attack. From there it went into my jaw and down my neck, around to my chest and down my back. It was the second worst attack that I have ever experienced. However, it is the longest lasting attack that I have ever had. At times I thought that I was going to die. Or maybe I was wishing that I would die. I guess it makes sense that the vaccine would have that effect on me seeing that my body treated it most likely as an allergy. Anyway, I'm about 70% over the attack and I feel that I can get back to working on Bricabrac.

And oh yeah, there is no way in hell that I am getting the second dose.

[Gabor Szots]

I have just read about it, terrible disease. I wish you the best recovery.

[mvanthoor]

...

That sucks... good luck with the recovery, Mike.

I've got my vaccination invitation in the mail two days ago. I'll see how it's going to be. Difference is obviously that I don't yet have your age, don't have fybromalgia, nor any allergies (at least, not that I know of).

[lithander]

Never heard of it and just googled it. Sounds really uncomfortable. Get well soon!

Are you planning to get a different vaccine as a 2nd shot or none at all?

I got Astra-Zeneca. Flue like symptons for two days, nothing too bad, but worse than any other vaccination I remember. In Germany Astra-Zeneca has a very bad rep and everyone want's the mRNA vaccines instead. Well, good for me otherwise it wouldn't have been my turn yet!

[Mike Sherwin]

Thanks guys! I am getting better. I'd syat 85% recovered. I would have grinned bigger but it still hurts a bit, lol.

@Thomas - None at all. The first shot is supposed to be 80% effective and I'm good with that. Besides I'm pretty sure I was already exposed. I had a low grade fever for 4 days a few months ago with no other symptoms. I have B- blood type and I have read that 19 is not very bad for people that have B- blood and many may even be immune. I'm just going to roll the dice. Fibro is worse than death anyway.
