},
{
fen: 'rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3 0 1',
move: '1. e4',
analysis: 'White opens with the King\'s Pawn, the most popular first move, controlling the center and freeing the bishop and queen.'
},
{
fen: 'rnbqkbnr/pp1ppppp/2p5/8/4P3/8/PPPP1PPP/RNBQKBNR w KQkq - 0 2',
move: '1...c6',
analysis: 'The Caro-Kann Defense! Black prepares ...d5 while maintaining a solid pawn structure. This is more solid than the Sicilian but less dynamic.'

move: '2. d4',

fen: 'rnbqkbnr/pp2pppp/2p5/3p4/3PP3/2N5/PPP2PPP/R1BQKBNR b KQkq - 1 3',
move: '3. Nc3',
analysis: 'The Classical Variation. White develops and puts pressure on d5. This leads to rich middlegame positions.'

fen: 'rnbqkbnr/pp2pppp/8/2pp4/3PP3/2N5/PPP2PPP/R1BQKBNR w KQkq - 0 4',
move: '3...dxe4',
analysis: 'Black captures the pawn. The main alternative is 3...Nf6, but this text move is the main line.'
},
{
fen: 'rnbqkbnr/pp2pppp/8/2pp4/3PP3/2N5/PPP1NPPP/R1BQKB1R b KQkq - 1 4',
move: '4. Nxe4',
analysis: 'White recaptures with the knight, maintaining central presence. Now Black must choose how to develop.'
},
{
fen: 'rn1qkbnr/pp2pppp/8/2pp4/3PP1b1/2N5/PPP1NPPP/R1BQKB1R w KQkq - 2 5',
move: '4...Bf5',
analysis: 'The key move! Black develops the problematic light-squared bishop outside the pawn chain before playing ...e6. This is what makes the Caro-Kann so attractive.'
},
{
fen: 'rn1qkbnr/pp2pppp/8/2pp4/3PP1b1/2N2N2/PPP2PPP/R1BQKB1R b KQkq - 3 5',
move: '5. Ng3',
analysis: 'White attacks the bishop. 5.Nc5 is the alternative, but Ng3 is the main line, forcing Black\'s bishop to make a decision.'
