Indian Defense Seirawan Attack (1.d4 Nf6 2.c4 e6 3.Bg5) Chess Puzzles

The Indian Defense Seirawan Attack is a sharp Indian-Defense line where White aims for an early kingside initiative, typically by committing to a fast attack plan rather than slow development. A defining feature is that White’s setup is designed to meet Black’s flexible Indian structure with direct pressure on the kingside, often involving a quick piece deployment and pawn breaks that create tactical threats. (I don’t have a reliably documented, exact move-order for the Seirawan Attack in this specific Lichess family, so I’ll focus on the position/plan features rather than a precise sequence.)
