Very similar to Play 1...d6 Against Everything by Hickl (also published by New In Chess) and the old Nigel Davies' Chessbase DVD for the "busy person" discussed here http://www.chesspub.com/cgi-bin/chess/YaBB.pl?num=1258989027

I have always thought the queenswap Philidor with doubled e-pawns is no fun and simply bad for Black.  An odd choice to promote this variation in the excerpt.  I would rather avoid it via d6, c6, Qc7 and only then e7-e5, which i recall Davies recommended on his old DVD.

Just back from the second of my three summer 'aways' to see these great posts. Excellent stuff, Eric -- thanks for it! It seems to me now (admittedly on just a quick butcher's) that 7 ...Qc7 must be better than 7 ...f6, as you suggest. V. useful Saemisch analogy, too ...

All this has got me thinking how superficial most of the literature I've seen on the KIA is! I can think of at least two good reasons why no one might be massively keen on writing a good book on the subject, but you'd have thought someone would have managed to dig down a bit rather than recycling the same half-dozen lines of old 'analysis' and 'famous games'! ...

I wonder if there is any concrete indication/acknowledgement that White should be able to achieve a slight advantage against the Philidor and the Old Indian. 

I noticed that in an instance of the "Pickett Shuffle," White plays an "!" move, then Black plays a "?!" one, then Black equalizes.

OK, the section is finally back on track! Smiley
Many thanks to Glenn and David for their help, I've personally found the updates even more interesting than usual - different writers are interested in different opening lines!
I see that Max hasn't even looked at my messages on Facebook/Messenger so it is definitely time to find a good replacement, however, I will first ask Ruslan if he is free, you never know! Wink

I thought of Smyslov,  who played everything. Does he make the cut? I think he might be the most underrated world champion. He certainly did a lot for theory in some defenses to d4.

You don't need SLI for Leela AFAIK, nor is Leela going to be bottlenecked by the PCIe bus.

SLI is a graphics tech, there are no scanlines to draw in a chess engine.


When did I say SLI is needed for Leela? I don't think I mentioned it. If I did, it was a mistake, sorry for that. But I think I wrote the opposite, that I can do fine without (with two RTX 2060, which do NOT support SLI).

If pointed out as a side note that if I were GAMING, SLI (or NVlink for the the high-end RTX 20xx-series) might be an important option, although sometimes it scales well, sometimes not.

Leela is not bottlenecked by the bus, but a fast GPU might very well be, and therefore Leela might be bottlenecked by the GPU. Here is the first article I found by googling:
https://www.techpowerup.com/review/nvidia-geforce-rtx-2080-ti-pci-express-scalin...

Here is another article:
https://www.pugetsystems.com/labs/articles/NVIDIA-GeForce-RTX-2080-Ti-PCI-Expres...

I am not sure if this matters in practice, though, because I don't know how exactly data is shuffled over the PCIe bus.

Anyhow, I'd say a mobo with support for 8x/8x instead of 16x/4x seemed worth the money for me. But perhaps this won't matter at all with RTX 2060. In that case I am at least a bit more future proof, hopefully (who knows what happens in computer business).

Very late reply, but can't white then try 6.Bxc6 pretending it's the Anti-Berlin? The extra move a6 doesn't look to me like it makes a huge deal of difference.

"Skimping on the PSU seems unwise, but 1000W seems to be PSU-underload."

The only hardware problem I have during many years and many computers, is a broken PSU. The PSU was at that moment a couple of years old. I assume the heat it produced, was in the long run the cause. Electronic components ages faster if the temperature goes up.

I think its better to have a slightly oversized PSU, which gets little bit cooler, than a PSU used to it's max limitation.


Yes, indeed, I agree. The main problem with slightly oversized PSU seems to be sub-optimal efficiency. With undersized, there can also be more noise, which is more annoying for most people, me included.

I was debating with myself whether to go for 750W, 850W or 1000W. In the end, I think I might have been ok with 750W, but 850W should be totally fine. I found an online calculator, that gave 750W I think, even when choosing a bit higher-speced hardware. 1000W might have been an option if I had decided on 2xRTX 2080, but that has never really been more than a distant dream for me!
