The road to the tabiya
Step through the move order. Amber moves carry an idea — read them, don't memorise them.
Why this matters
Take on c4, push ...b5 and ...c5, and turn your 'passive' triangle into a rolling queenside majority with the bishop on b7 firing.
The structure: Meran (queenside majority vs centre push)
Black's a6/b5/c5 vs White's a2/b2 on the queenside; White's d5/e4 vs Black's e6 in the centre. Black's bishop on b7 and knights on c5/f6 vs White's bishops. Whoever's pawns create the first passed pawn or open the first file wins.
Trades: yes and no
Trade White's light-squared bishop (via ...c4 and ...Nc5xd3) — it's the attacking piece. Trade queens only after your c4/b5 pawns are safe. Don't trade your b7 bishop for a knight while the long diagonal is open. Avoid ...exd5 when White recaptures with tempo on a loose piece.
Motifs to watch
- ...c4 with tempo on the d3 bishop, then ...Nc5
- ...exd5 exd5 Bd6 hitting h2 with rook to e8
- White's dxe6 fxe6 then Ng5/Bc2–Qd3 battery — keep ...Nf8 or ...Bd6 ready
- The ...Nc5–e4 jump over White's structure
