What the game does with openings
RoChess! recognises more than 3,800 openings as you play. That is a naming aid during the game. It is not a shop list of five lines, and it is not a ranking. The names below are ordinary chess move orders you can play inside RoChess!. The learning order on the tier page is an editing suggestion for new players, not an engine result and not a developer ranking.
One job in the opening
Get minor pieces out, put something in the center, and castle before you start a hunt with the queen. If you move the same piece three times while the rest of the army is asleep, the recognised opening name will not save the position.
Five setups that are enough at the start
Italian Game. 1. e4 e5 2. Nf3 Nc6 3. Bc4. The bishop looks at f7. Knights develop before a pile of pawn moves. This is the simplest active start for a new player.
Ruy Lopez. 1. e4 e5 2. Nf3 Nc6 3. Bb5. The bishop pressures the knight that defends e5. You do not have to take on c6 at once. Develop and castle.
Queen's Gambit. 1. d4 d5 2. c4. White offers a wing pawn to argue about the center. Take, decline, or protect d5, then develop. Chasing the pawn forever is the usual beginner trap.
Sicilian Defense. 1. e4 c5. Black fights for the center without copying 1...e5. The positions get sharp. Use it after the Italian ideas already feel normal.
French Defense. 1. e4 e6 2. d4 d5. Solid, and the light-squared bishop can be hard to develop. Plan the bishop before you lock the center.
After the name appears
If RoChess! prints an opening name, compare it with the move order you intended. Then look at the board, not the label. A recognised opening can still hang a piece on move eight.
Play these as White or Black ideas against an easy bot until the first six moves no longer take your whole clock. Then take the same idea into one rated game and review where you left the plan.
