We are reaching the Max Odds that a top engine can give the top 3 GM's

Well, this was fun. Tried an Alekhine again, only this time the odds was the k-side knight. Didn’t think I could torture Stockfish to death (well, I can’t, other than with a knight odds), but, well, see for yourself ...

A common theme of this series is that SF starts creating a good position, then you negate that by finding a simplification. However, in this game, something different happened: in the forties, while your king went on a long march to join the attack, SF was reduced to lame time-wasting moves. It has been a while since I've seen this kind of behaviour from a strong computer.

Maybe you could try Larry's suggestion and set contempt to the max value to reduce SF's willingness to allow simplification?

This clearly show us that Stockfish is NOT the best program to give Odds greater than Knight specially to Humans

[Chessqueen]

Very soon either Stockfish or Komodo will be able to give a Knight odds in TC of 2'+1" to the top 3 GM.s, but we are really witnessing the maximum odds that any engine would be able to give to the 3 top GMs, since none of us will be able to see an engine giving a Rook Odds with a TC of 2'+1"

The real challenge here is for an engine to give knight odds in Rapid (15' + 10") to GMs, at least with Armageddon rule that White (the odds-giver) wins draws. I think this is already possible with low-rated GMs (low 2400s). So the goal can be to gradually increase the rating of the GM to whom an engine can win say a five game Armageddon knight odds match. People expect blunders in blitz, but 15' + 10" is now the most popular time control for Elite events, especially online, so this is supposed to be a serious time limit where strong players should not make too many simple blunders. Whether an engine will ever be able to beat the world's best Rapid player this way is unknown, we are far from that point now.

Knight Odds to IM Daniel Rensch is possible NOW with T/C of 15'+10" with latest Komodo or Dragon 2 using either 4 threads or 8 threads ==>

Could do except I don’t have a Dragon or a Komodo. On the other hand, if Larry Kaufman wants to send me one, the. I can give it a try. Personally, I doubt there’s any engine I can’t give knights odds to just as long as I (or anyone else who is reasonably strong) to any engine as long as I can concentrate without being under taps game time pressure. Note that all Larry’s actual offers against GMs and IMs stipulate quite rough time conditions, so Dragon is really relying on blunders.

What type of computer would you use to play against Dragon if we send it to you (there is no Dragon for iphone)? Of course it is fine to play at a longer time control; we use 15' + 10" for many matches with GMs (including Hikaru) as that is now the standard time control of the top level events online, as well as the World Rapid championship over the board. While ordinary masters may blunder often at that time control, the top 10 GMs are quite used to it and should usually only make small mistakes. In earlier years we ran many GM matches at 45' + 15", a reasonably slow rate of play. Of course you won't be able to duplicate the conditions of our matches; even if you own a 32 core threadripper or something comparable you still won't have the opening book we use for these matches, but even on a normal computer with just four cores, without the book, I will be impressed if you can score 50% or better at knight odds (alternating b1/g1) with Dragon 2 set to use MCTS and Contempt set to anywhere in the 150 to 200 range.

While ordinary masters may blunder often at that time control, the top 10 GMs are quite used to it and should usually only make small mistakes. In earlier years we ran many GM matches at 45' + 15", a reasonably slow rate of play. Of course you won't be able to duplicate the conditions of our matches; even if you own a 32 core threadripper or something comparable you still won't have the opening book we use for these matches, but even on a normal computer with just four cores, without the book, I will be impressed if you can score 50% or better at knight odds (alternating b1/g1) with Dragon 2 set to use MCTS and Contempt set to anywhere in the 150 to 200 range.

I have a range of PCs. From 64x threadripper to 6x i7 laptop through some 6x i7 PCs, all with GPU, but I don’t suppose Dragon is using GPU?
In practice, I quite like the iPhone, because then I can play a few moves on the cafe or whatever. I’m pretty unlikely to sit down for a serious time controlled session - I get too many interruptions.
So, probably the laptop. I guess, being reasonable, can human hold against computer, I’ld suggest “friendly” correspondence conditions for me and game in 15 for you. I’m pretty busy right now.
Alternatively, play move by move in public forum. I’ll have to trust you to stick to move as game in 15, and you’ll have to trust me to not ask Stockfish. Anyway, you could tell if I was using comp help. And kibitzers could keep their mouths shut.
Ed’s forum? I’m sure he could set something up.
