Reading the queening square before you push
A pawn on the seventh is one push from a new queen, and the position turns on a single question you can answer at a glance: is the square in front of it clear, and who watches it? In these puzzles a defender is parked there on purpose. Sometimes a piece sits flat on the promotion square. Sometimes it guards the square from across the board. Train yourself to check that square first, before you calculate anything else.
Once you spot the blockader, two motifs handle it. A clearance sacrifice knocks the piece off the eighth rank, even for material, because the queen you gain pays it back at once. A deflection drags the lone defender off the square it watches, and the pawn walks in. Look for the finish that promotes with check, since the opponent has to answer the king and never gets a move to round up your fresh queen. The drill is to see the check first, then back up to the move that forces it.
Spotting the underpromotion before you reach for the queen
Most pushes take the queen and never look back. In this set a small fraction go another way, and those are the ones to drill, because the board gives you a cue if you know the shape to look for. Before you auto-queen, scan for two pictures.
A knight that lands on king plus a piece. When the promotion square is a knight's move from the enemy king and a second target sits on the other prong, that is your fork. The knight reaches squares the queen cannot, so it checks and wins material where a queen would only sit and threaten. Why a queen would fail here is covered in the promotion guide; on the board you just hunt for the double-hit.
An enemy king with no legal move. If the king is already boxed and your new queen would blanket its last square, you are one move from handing over a stalemate draw. The cue is a cramped king and a thin escape. The rook is the usual fix, since it covers the file and rank without the diagonal that traps the king; the bishop version is rarer and position-specific. Underpromote, leave a flight open, and keep the win. I lean on the rating slider here, around 400 to 2400, and push it up until these quiet refusals stop catching me off guard.
Counting the pawn race down to one tempo
Pawn races are won by counting, not hoping. Both sides run for the far rank, and each puzzle in this group hands you a position where one tempo settles it. The skill is reading who queens first and whether that first queen arrives with a threat or just stands there.
The count is quick once you trust it. Tally the moves each pawn needs to reach the last rank, then ask what happens the instant the first queen appears. A queen that comes with check, or that controls the opponent's own promotion square, ends the race before the trailing pawn arrives. That swing is what you are hunting. A breakthrough sacrifice can also spring a passed pawn nobody can catch, turning a level count into a forced finish. Keep promotion separate from the passed pawn itself: the passer is the deep runner, while promotion is the moment it finally queens. Advanced pawn puzzles drill the runner.
