Convert an extra pawn: create a second problem before simplifying
An extra pawn is an opportunity, not a result. Compare king activity, pawn structure and the ending left by an exchange before trying to simplify.
Make the advantage usable
An extra pawn matters when it can become a passer, draw a defender away or support a king invasion. First identify where the surplus pawn sits and what prevents it becoming useful. A doubled pawn behind a blockade may contribute less than an equal-material position with a much more active king.
Compare weaknesses on both sides. If your king is tied to defending a pawn, moving the extra pawn may only open a route for the opponent. Improve the least useful piece or king square before committing the structure. The aim is to reduce the defender's good choices, not to push simply because you own more material.
Trade toward a position you understand
Exchanging pieces can reduce counterplay, but the resulting pawn ending may be drawn or even lost. Calculate the king routes, opposition and promotion races before accepting a trade. A favourable material count does not survive every simplification in the form of a favourable result.
Keeping pawns on both wings can give the defender two tasks, while exchanging too many may leave a fortress. On the other hand, preserving every pawn can expose new targets. Decide which weakness you will attack after the first one is defended. A second useful target can make a stable blockade harder to maintain.
Run a conversion review
Choose a completed game where you had one extra pawn and the game continued for several moves. Stop at the first plausible exchange. Write the resulting ending you expect and the defender's main resource. Play the position without hints, then review the exact decision rather than the final result alone.
For a second attempt, keep the pieces on and improve activity before pushing. Compare the defender's available counterplay in both versions. If neither attempt creates progress, state why: a blocked pawn, a checking rook, king distance or a fortress. This is useful diagnosis even when the correct result is a draw.
Measure decisions rather than conversion streaks
Record one irreversible decision per practice game: a pawn push, an exchange or a king commitment. Explain what it improved and what it gave up. A win after an opponent's mistake should not automatically validate the earlier choice, and a draw against accurate defence may reflect the position rather than poor effort.
Retest the critical position later from the defending side. Try to preserve the resource you identified. If your original plan only wins when that defence is ignored, revise it. Successful conversion practice teaches how an advantage becomes a concrete problem for the defender, not how to expect a win from a plus-one material count.
Before a pawn push, consider whether it leaves a target behind. A passer that demands your king's permanent protection may not help you invade elsewhere. Test the defender's simplest blockade first; if your plan only works against an unnecessary capture, you have not yet shown how to make the extra pawn count.

Where Brass Pawn fits
Brass Pawn's engine games and limited endgame drills let you practise conversion decisions. Its feedback helps locate mistakes; it does not guarantee that every extra-pawn ending is winning.
