How do I make a conditional move in daily chess?

You have to be on the website and it has to be your opponent's turn to move. When that is the case there will be an icon that looks like a forking arrow. Click that and you will be able to enter conditional lines.

There are too many forking arrows...

You have to be on the website and it has to be your opponent's turn to move. When that is the case there will be an icon that looks like a forking arrow. Click that and you will be able to enter conditional lines. this is one of the issues with the new interface. there used to be a tab that simply read, "conditional moves". even if replacing that with an icon was due to language barriers, who made up the icons? is there a table a governing chess body has for these that us internet players do not know?

They designed something. There is a tool tip on every button so anyone that doesn't know what it is, can figure it out by moving their mouse over it; if there isn't a tool-tip it's because a new menu appears instead. It will be presented in the language they have defined on the site as well.
In fact, the icon is related to the one in v2. Though, that one has a knight and the same forking arrow (hidden partially by the knight).

@TBAckler Glad you found it, from memory it looks something like this 🔀

I assume my opponent cannot see the conditional moves that I enter, right?
If they make a move that you have predicted, then they will automatically see the move that you have set up along with a message along the lines of "Your move has triggered a conditional move by your opponent. It is your turn again!"
However, before they move, they will not know that you will have any conditional moves set up or what they are. And if you have multiple lines set up, they will only know of the one that they follow, after they make their moves that follow the line.

this sounds not much less than using an engine to play your opponent. it should be another category and your opponent should be able to make the same number of 'conditional' moves. you will nvr convince me this ACTUALLY makes you stronger. I am new to learning this game. It sounds like this, though: "if I hit 10 shots from the tee box, select the best, swing 10 more, and so on, but my opponent may only take one swing" ...yes, I WILL shoot a 52 (e.g., gain a rating of 2800), and I win! BFD I don't get it. and this is straight up?

You obviously don't know what Conditional Moves are; they are basically anticipating your opponents next move and entering it in advance of it being your turn.
