Puzzle Walk Part 2: Puzzles from the 1830s

This post is a continuation of delving into chess author George Walker's body of work (1803 – 1879), specifically it will translate the next 10 puzzles in his set of 50 puzzles published in his book "New Treatise on Chess" from 1832 (link goes to archive.org) .

My previous Walker post are available below, including one with the first 10 puzzles in the set:

• Walk This Way : Chess Maxims from 1846
• Puzzle Walk Part 1: Puzzles from the 1830s

These puzzles were translated from 1830s descriptive notation used in George Walker's book. Some puzzles come with stipulations from the author that make the puzzle more unique and challenging (e.g. instead of the fastest mate, the mate must come with a pawn). When this is the case the rules will be listed with the puzzle. Puzzles are from white's perspective unless noted otherwise.

Puzzle 11:

• White must mate with the pawn that starts on g6
