Claimeven - Connect 4 Strategy

The term 'claimeven' was coined in Victor Allis's paper 'A Knowledge-based Approach of Connect-Four'
...or at least that's where I think it came from.

and thanks for the tunes, tim!

The entire video I was waiting for a mathematical generalisation, but it's just a genuine connect 4 strategy

[thewoodpeckers]

Today I learned that connect 4 experts exist

This is not what I thought I wanted but this is what I needed.

My understanding of claimeven is that it can be used for a lot more than simplifying endgames, but my understanding is also less well-defined. This is a good starter to claimeven for sure

And now to use this information to absolutely obliterate my friends at connect four, thank you

I was so confused at first with the final example, it took me a second to realize you were looking at it from red's perspective now
Also, this was super cool and I'm really interested in learning more!

[RESPRiT]

Really cool learning about how large the expressive space of connect 4 is and how players have started to carve it up, thanks for sharing!

Nice video! it's always satisfying to see someone break down complex things to intuitive bits.
I've seen there's a solver for Connect 4 and it often leads to the call-and-response - thought it was because the losing side is stalling... but turns out either side can lose without precisely knowing when to use it or not.

Me and my friend have played semi-serious connect four for the longest time. I got super into counting evens and odds to try and figure out the best move, but this blows all of that out of the water with how much simpler and more effective it is!

This is a good introduction to claimeven! I'm betting more people will be able to easily and intuitively pick it up after watching this

OMG I'm so glad I found this channel. I played a ton of connect 4 as a kid. I was quite good (so I thought) and hardly ever lost. I really liked math and abstract algebra and I played the game a ton. Later, I stopped playing connect4 in favor of Rubik's cubes.

Recently one day when I was bored I picked up the game again online and was once again fascinated by all the cool and unique problems it threw at me. I got smashed by a few players and learned from them. I love this game so much.

Your video quality has improved alot since the first 2swap introduction to connect 4 strategy

[alio]

I got my friends obsessed with connect 4 in high school good to know there was some sense in the strategies we made

[mnzznxplay]

I don't have much experience with connect four, but I won class championship with similar strategy. It was eleven years ago, but I still remember that there was spot that would give me win, but only if opponent places stone before me, so we filled rest of the board so no one would win until we get to here. Somehow I figured out that if we'll do that then my opponent will be first to put stone in column, so I had only to stall for time

always a good day when you upload. my friends are super impressed when i demolish them with my new skills

@twoswap I’m curious. Do you know the game Eternas? If you don’t it’s literally connect 4 but designed in a circle. The pegs that create the height only allow for four balls vertically (which of course also means 4 diagonally). It’s a very interesting game and I wish both of these games had a more competitive scene.

I’m already rubbing my gremlin hands together with a huge crooked smile, waiting for my spoiled brat 10 year old cousin to come over again

[memcgee]

always love a new upload from you. Keep it up!

Hello, for rendering the boards if you could please make a small indicator to tell who's turn it is to play I would appreciate it. Thanks.

I think a smaller version of the connect four token of each color on the bottom left and bottom right of the board, going from the faded to solid depending on who's turn it is. The solid should mean that that player will place the next token.

I didn't expect to see a connect 4 strategy today
