Chess is hugely easier to calculate, and as such there are strong ab search engines that can run on CPUs instead of GPUs.
You dont need a hugely powerful GPU to beat pros on a even game with Leela. A GTX 1650 for 150e running in fp16 mode would probably be enough (even though you might want to get a card with more memory, i dont know if a 40b network will fit in 4gb)
Naturally, a intergrated intel gpu, or a old laptop gpu wont work very well, but you can always let it think for longer.
Edit: none of this will however "solve" handicap play
Edit2: what are you using to run leela btw? If its Lizzie you should note that its distributed with a very old, rather weak network that you need to update yourself

leelaz-model-swa-24-192000_quantized Is this the right weight file?
https://www.youtube.com/watch?v=FV6dSjnx7jY It was recommended by that video.
I lost to leelaz by 3 points at 3 stones, so I have a hard time believing it could beat a top pro at 3 stones.
That's the funny part, you will always lose by like 3 points. You will never beat it.

Maybe, but I beat it repeatedly by like 50 points at 5 stones.
I tried ignoring its moves in the corner, sometimes ignoring everything and making a loose line of stones down the center. It isn't the best way to win, but it leads to a better games than playing against 3x3 point invasions and just trying to make moyo into territory.

How many times does it need to be repeated that it does not know how to play high handicap?
Whatever you try at 5-4-3 stones, even 2 stones handicap, is completely irrelevant.. its not what it was designed to do..
(EDIT: And do note.. when the handicap goes higher, the bot gets much worse. It is NOT a linear weakening according to the amount of handicap stones..)
Now.. us wanting to have a bot that CAN play high handicap, thats normal, and many people are working on that (check out KataGo for example),
but just because you want it be able to play high handicap, and you thinking it should be able to, does not make it so..
Normal Go thinking around handicap and handicap systems does not apply here.. anyone testing or trying to say anything about the strength of go bots by handicap.. well.. useless information (sorry)

Yes. Top level bots are trained on even games between evenly matched opponents. High handicaps trigger attempts to win the game that is almost certainly lost. With humans that leads to plays called
looking for a place to resign. OC, when humans give high handicaps they assume a certain level and type of mistakes by Black. Those bots have no training under such conditions.

I play @Tygem with LZ, exclusively with my Split-Fusekis (which are inferior Fusekis). I had no problems reaching 9d. Within 9d it's 50/50, but I also did beat a 2p once. I play with #158 the old traditional one.

I just checked and name of bot i mentioned earlier is "geomancer2".If you still dont believe in LeelaZero strenght (and i think you dont) try to give it a shot.I checked games and it beat some 1d on 9 stones,2d on 6 stones, and 4d on 3 stones - though it also lost to some 1d on 4 stones (all KGS games).Imho worth try if you doubt in Leela power.

Try Katago, anything above 2 stones for LZ starts to make it play erratically.
You probably won't beat the new version with 5 stones, I've only seen it lose at 8 stones
