Greed is Bad
It's one thing to snatch a pawn in the opening, but best to avoid making any declarations in the centre with your King in the middle.
On the White side of a Sicilian Kan against CM Thanh Tu Tran, I was expecting retraint in the centre with 11. ... d6. Instead he shocked me with 11. ... d5. I sensed something wasn't right, with a lead in development and King still in the centre. After 12. e5 Nd7, can you find what I played as White?
