Youtube channel for Splendor analysis

Post by druzil »

Hi everyone,

I've started a youtube channel where I analyse Splendor replays using a alpha-zero style engine that has been trained to a high-level

Here is an example of the current generation

https://youtu.be/d4lpbIGd_SA

I'm trying to continually improve the quality so any feedback is appreciated.

Also if you are interested in having your games analysed you can post them below or message me directly. Just note currently I only analyse 2-player games (no expansions) and can't analyse games with moves containing reserving from the hidden deck.

Respectfully, the narration is extremely bad.

"Player 1 does x, player 2 does y" is not interesting. I can see what moves are being played. I want to know what those moves accomplish both offensively and defensively, what future lines they are threatening, what alternatives could have been considered. When the narration does mention something like this, it's often totally random and meaningless. For example, at 5:39 the narration mentions that the gold gained from reserving a card, will make a tier 1 white card affordable. So what? Look at the state of the game -- does it matter at all that the tier 1 white card is now affordable? The very next move" player two takes [whatever]. The engine disagrees, and prefers [something else]" Why? Take a moment to explore the consequences of both moves to explain why the engine prefers something else, otherwise what's the point of even mentioning it? The AI is just saying things for the sake of saying them -- which is all AI can really do, tbh.

Check out Gothamchess youtube channel for an example of game commentary that makes good use of engine analysis while also providing useful strategic insight. You will need to put more human thought into your narration, instead of leaning so heavily on AI.

Thanks for replying.

I agree that more narration needs to be done on strategic decisions, this happens more frequently from the middle to the end of the game - I'm wondering if you watched that far or got put off before getting through. Early on there are many similarly weighted moves so its difficult to focus on one plan early on. Splendor is not as tactical as chess so it doesn't lend itself to exploring many different tactical lines beyond a depth of 1 or 2.

In terms of improvements would it be useful to not mention moves at all, and just jump quickly through a number of moves until an 'interesting point' occurs. Perhaps not even show parts of the game at all and then just jump to particular positions which can then have more lengthy strategic commentary on? I want to keep the videos under 15 mins.

You mention Gothamchess, my inspiration actually comes from agadmator who I think does this type of analysis using an engine perfectly.

Hi! It's really interesting you made an splendor AI. I've noticed that there are several splendor AI engines, such as CN_Geminus, on BGA and Spendee. I'm really interested in watching these AIs compete against each other and learning from their strategies and moves.

If you're interested, I'd be more than happy to help arrange matches between different AI engines.

Hi everyone,

It’s great to see so much interest in Splendor AI lately! I wasn’t really aware of CN_Geminus or the Spendee bots, but I recently launched https://kirameki-lab.com, a site where you can play Splendor against an AI I built. The goal is to help people improve their play. If you’re curious, feel free to give it a try!

One thing I put a lot of work into: besides token exchanges, the AI handles all the flexible payment options from BGA’s advanced mode. For example, it can choose to pay with gold even when it could afford a card with regular gems.

I’ve also been seeing Splendor AI come up in a lot of places recently. It would be really fun to agree on a standard API so different engines could play each other on a shared platform!

And there went CN_Geminus, hadn't run into them before and wasn't aware there were bots about for Splendor until seeing this thread. Also did not know there was a site called Spendee, not familiar with how it works.

I glanced in myself, the analysis is definitely weak. Looking at that starting board and "black is prominent among the visible tier 3 cards"? A number existing in a few spots doesn't make it prominent. Prominent is that red is not only the most relevant noble color in what looks to be a slow board but is also the only color in the 3-point red that serves as the only quality point scorer on the board, with the 6/3/3 4 point black a distant second (with red notably being its lead color, and the rest being very behind the curve cards. All that, and the only other red on the table is the way off curve 3 pointer, which could come along if things stay in this weird direction but isn't exactly something players typically target. Instead, row 1 looks like a fight for the blues to transfer to the cheap white cards, or maybe even nabbing the awkward level 1 blue first to get there better. At this point one wonders if the top of the deck will end up driving the conversation instead. This major mismatch between the low number of scoring cards and the near nonexistent overlap it lack with lower-level cards to grab is itself a major fact, the one of the main ideas of reserving high-power cards to prepare super-efficient buys is in a remarkably terrible position here, which means the way many players would approach this board may be significantly different than how they'd conventionally tackle other openings.

The first player (the player who goes first, which thanks to the replay POV was called player 2 in the video) snatches the 3-point red, the best card on the table, at the expense of their token initiative, important for blue, but with their second reservation in a row they give their opponent 3-1 initiative for blue and black, and poor reservation decisions lead to a cramped situation with their clogged hand and token access. This seems like a major strategic matter that wasn't given the attention it deserved in the video.

I would go with fast forward and avoid skipping. Everything in the game should be visible to avoid accidently leaving out a relevant detail to following the path of the game but choosing which parts to emphasize is a good idea. Still present so players can pause and consider something they thought was important/worth viewing but not taking up much time if you don't think it has anything you need to go over.

We don't need empty facts. There should be a point to the details given, saying you can buy a card no one is even looking at is not worth anything unless you're aiming to make a case that they should care and missed something important, etc.
