SICILIAN TRANSPOSITION
CENTRE GAME towards DRAGON VARIATION
Black declined the immediate QP to avoid the Morra Gambit and instead set his own QPawn on Q3(d6) to support his QBP, free his QB and deter 3.P-K5.
White transposes towards the Dragon line by developing his King's Knight to KB3(f3) to double his QP support and enable 4.P-K5. W-Alt.
