Quick summary

Nice win — you converted a simplified advantage after active piece play and a clean exchange sequence. In the loss, the opponent used a fast queen attack and mating net while your king was exposed in the center. Below are concrete, practical suggestions to keep your wins and avoid those sudden mates.

Games to review

• Win (good conversion): Review your win — opening was the Scandinavian Defense, you traded into a favourable endgame and closed it out.
• Loss (mating net): Review the loss — opponent used early queen activity and decisive checks; your king ended up in danger after centralizing moves.

What you did well (so you keep doing these)

• You converted material and structural advantages by simplifying into a winning endgame — that shows good practical sense: when ahead, trading pieces is often correct.
• Active piece placement: in the win your pieces found useful squares and coordinated to create threats and limit the opponent's counterplay.
• You're willing to go for sharp lines and complications; that yields wins when your opponents slip.

Main areas to improve (concrete and actionable)

• King safety and checks: in the loss you were vulnerable to a queen check/visit that led to mate. Before moving the king into the center, ask: "Can the opponent check me or deliver a mating net?" If yes, fix it (create luft, interpose, or exchange queens).
• Responding to early queen activity: when the opponent brings the queen out fast, prioritize development and look for ways to neutralize the queen (trade safely) or block its access to key squares rather than launching unrelated pawn pushes.
• Prevent back-rank tactics: even if you have an attack, check whether your back rank is weak. A simple pawn move to give the king a flight square can save you from sudden tactics.
• Opening consistency: you play the Scandinavian often — it's a solid choice. Tighten your main line knowledge so you avoid early awkward queen excursions by your opponent and you know typical plans to reach a comfortable middlegame.

Short training plan (daily/weekly, practical)

• Daily (10–20 minutes): tactics puzzles focused on queen checks, forks, and back-rank mates — for three weeks prioritize puzzles that end with mate or decisive checks.
• 3× per week (20–30 minutes): play one rapid game and review it immediately — ask "why did a blunder happen?" and mark one recurring theme (king safety, missed tactic, time trouble).
• Weekly (30 minutes): endgame practice — basic rook endgames and king+pawn vs king conversions. This complements your strength in converting advantages.
• Opening work (2 weekly sessions, 15 minutes): choose two Scandinavian lines you play most and learn 2–3 typical middlegame plans and one tactical motif the opponent uses (so you can parry it quickly).

Practical tips to use during games

• After any check, pause and scan for enemy follow-up checks or queen sacs. If there is a forcing continuation, prefer neutralizing it rather than chasing material.
• When ahead, simplify but keep an eye on pawn structure and rook activity — trading into an endgame is good, but only if your king is safe and your rooks can be active.
• Create at least one luft (a pawn or minor piece move) when your back rank is tight and queens are still on the board.
• If your opponent offers queen trades while you’re under pressure, lean toward trading if it eases your king safety — even if it costs a tempo.

Specific moments to study in those games

• Win: follow the sequence where you exchanged into a rook end and consolidated. Note which exchanges simplified your opponent's counterplay — emulate that decision process in future games: trade when it reduces opponent activity.
• Loss: watch the queen checks and the final mating pattern. Ask: could you have prevented the queen's route or created an escape square earlier? Practice the same motif in puzzles until it becomes automatic.

Next steps — checklist for your next 10 rapid games

• Before each game: 2-minute review of your chosen Scandinavian lines and one common trap your opponent uses.
• During game: if your king is exposed, and a queen appears, prioritize safety — make one prophylactic move (luft, block, or trade).
• After each game: mark one instructive moment and write a 1–2 sentence takeaway. Repeat the same theme until you stop making that mistake.

Encouragement

You have a lot of experience and the right instincts to convert advantages. Fixing a few recurring things — king safety against early queen activity and a little structured opening review — will convert more of your close games into wins. Keep it simple, practice the specific motifs above, and review the two games linked earlier.
