An Easy Nostalgic Puzzle (1737)



after 3. QxR .. Nb8xNc6 so it would be rook for two knights
4. Rxc6 looks like it could get white into trouble, but i'd need to spend longer than i want to looking at it (there's the threat of Qf3+ to win the rook and also to push the pawn for promotion if the white queen defends the rook)
