THE USEFUL BIT

2 ChatGPT Prompts to Analyze Match Screenshots for Highest Scoring Half

A football match can have more goals after the break even when the first half looks lively. The reverse can also happen: an early burst of goals may make the first half the highest-scoring one. That is why Highest Scoring Half needs a comparison of goals in the two separate periods—not just a team's full-time goal average or its recent wins.

In the standard market, you select which half will contain more goals across both teams combined:

  • First Half: more goals are scored before half-time than after the interval.
  • Second Half: more goals are scored after half-time than before it.
  • Equal: both halves contain the same number of goals.

For example, a match with one first-half goal and two second-half goals is settled as Second Half. If each half has one goal, the outcome is Equal. Check your bookmaker's exact market wording and settlement rules: official rules commonly include stoppage time in the relevant half and exclude extra time, but terms can vary.

These two prompts are designed to make ChatGPT read the screenshot carefully, look for half-by-half evidence and choose First Half, Second Half, Equal, or PASS. They are not prediction guarantees. If the screenshot only shows fixtures and odds, the model must not pretend that it has enough data to identify the likeliest half.

Prompt 1: Screen several matches from one screenshot

Use this when the screenshot contains a fixture list, odds or several Highest Scoring Half markets. For the best analysis, upload readable images and, where available, a separate statistics screenshot showing half-time scores or goal timings.

🟦 COPY PROMPT 1 — MULTI-MATCH HIGHEST SCORING HALF SCREENING

Act as a cautious football data analyst. Analyze every match that can be read in the screenshot I uploaded for the “Highest Scoring Half” market. Assess which half is best supported by available evidence: FIRST HALF, SECOND HALF, or EQUAL. You must also be willing to return PASS. Do not force a selection, invent goal-split statistics, or describe any result as certain.

STEP 1 — READ THE SCREENSHOT FIRST
For each fixture, transcribe the home team, away team, competition, kickoff date/time, match status, exact market label, the available selections, and any visible odds or statistics. Mark blurred, cropped, missing or uncertain items UNKNOWN. Do not guess team names, dates, odds, scores or market labels. If the match or market cannot be identified reliably, ask for a clearer screenshot or mark that match PASS.

STEP 2 — CONFIRM THE EXACT MARKET AND RULES
If web search is available, verify the fixture and date using reliable sources. Confirm that this is the match-level “Highest Scoring Half” market—not “team highest scoring half,” “second-half result,” “half with first goal,” or “HT/FT.” Check the bookmaker’s wording and settlement rules. Typical options are First Half, Second Half and Equal, but use only the options actually offered. Verify whether stoppage time counts and whether extra time is excluded. If the market or rules cannot be identified, state the uncertainty and return PASS.

STEP 3 — FIND HALF-BY-HALF GOAL DATA
For each match, seek reliable, recent, competition-relevant information, ideally around 8–12 matches per team when available. Prioritize:
- For each team’s recent matches, the number of goals scored by BOTH teams in the first half versus the second half.
- Counts for matches where the first half had more goals, the second half had more goals, or the halves were equal. Show the numerator, denominator and date range.
- Relevant home-team home records and away-team away records, with sample sizes.
- Goals scored and conceded in each half, and any consistent early/late scoring or conceding patterns.
- Opponent strength, competition level, and whether the sample is large and comparable enough to be useful.
- Confirmed lineups, important absences, rest/schedule context or tactical changes only when verified by reliable, current sources.
- Visible or current market odds, with the time checked, if available.

Do not substitute full-time goal averages for goal splits by half. A final score alone does not show how the goals were divided: you need the half-time score as well, or a trustworthy goal timeline. If browsing is available, cite sources you actually accessed and say when you checked them. If browsing is unavailable, use only the screenshot and information I provide; never claim to have checked current stats.

STEP 4 — COMPARE ALL THREE OUTCOMES
Assess FIRST HALF, SECOND HALF and EQUAL separately. The market counts goals from both teams together, not which team scored them. For example, a first half with two goals and a second half with one goal supports First Half for that historical match; one goal in each half supports Equal.

Explain what supports and weakens each possible selection. Do not use team reputation, a single head-to-head result, possession, full-time wins, or full-time goals per game as the only reason. Do not invent probabilities or confidence percentages. Historical frequencies describe past matches; they are not guaranteed probabilities for this fixture.

If goal-by-half data is missing, the screenshot is unclear, sources are stale or conflicting, the sample is too small, or you cannot distinguish the options responsibly, return PASS. Do not force a pick just to fill a list.

REQUIRED OUTPUT — ONE VERTICAL ENTRY PER MATCH
1. Fixture / competition / kickoff date:
2. Exact Highest Scoring Half market confirmed? YES / NO / UNKNOWN
3. Screenshot details readable? YES / PARTLY / NO
4. Historical first-half vs second-half goal data, with sample sizes:
5. FIRST HALF — evidence for and against:
6. SECOND HALF — evidence for and against:
7. EQUAL — evidence for and against:
8. Final assessment: FIRST HALF / SECOND HALF / EQUAL / PASS
9. Main uncertainty or missing information:
10. Sources and time checked, if web search was used:

Accuracy and transparent uncertainty matter more than generating many picks. Do not suggest a stake, encourage chasing losses, or describe any outcome as guaranteed.

Why this prompt helps: It asks for actual goal counts in each half and separates the three possible outcomes. It also stops ChatGPT from using a full-time goals average as a substitute for half-by-half evidence.

Prompt 2: Deep-check one match from a detailed screenshot

Use this when you have one selected match plus screenshots showing recent results, half-time scores, goal timelines, statistics or odds. A screenshot of the final score alone is not enough to reconstruct how many goals came in each half.

🟩 COPY PROMPT 2 — SINGLE-MATCH HIGHEST SCORING HALF DEEP CHECK

Act as a skeptical football data analyst. Examine the screenshot(s) I uploaded for one match and assess the standard match-level “Highest Scoring Half” market. The possible outcomes are FIRST HALF, SECOND HALF, and EQUAL; PASS is allowed when the evidence does not support a responsible assessment. Do not promise an outcome or manufacture a statistical edge.

A. IDENTIFY THE FIXTURE AND MARKET
Read the home team, away team, competition, match date/time, match status, exact market label, available selections, odds and visible statistics. Mark any unclear field UNKNOWN. Confirm this is the match-level Highest Scoring Half market, not a team-specific highest-scoring half or a related half-time market. If the period or market rules are unclear, ask for a clearer screenshot or return PASS.

B. VERIFY THE WAY THE MARKET IS SETTLED
If web search is available, check the bookmaker’s rules. Confirm how it treats stoppage time, extra time, abandoned matches and the Equal outcome. Do not assume every bookmaker has identical settlement terms. State any rule you could not verify.

C. VERIFY GOAL SPLITS AND RECENT FORM
If web search is available, confirm the fixture and inspect reliable statistics. Ideally examine around 8–12 recent competitive matches for each team when available, without pretending that the same sample is always possible. For each relevant historical match, obtain the half-time score and final score, or a reliable goal timeline, so goals can be split into first-half and second-half totals. Then count how many matches had:
- More combined goals in the FIRST HALF;
- More combined goals in the SECOND HALF;
- An EQUAL number of goals in both halves.

Show exact counts, denominators, dates and sample limitations. Also inspect relevant home/away splits, goals scored and conceded per half, opponent strength, competition context, and verified current team news when meaningful. Keep first-half and second-half goals as the primary evidence. Do not rely on full-time scores alone, because they cannot identify the goal distribution between halves.

If browsing is unavailable, state that you are limited to the screenshot and information I provide. Never invent half-time scores, goal timings, injuries, lineups, odds or statistics. Cite sources you actually consulted and note when the data was checked.

D. COMPARE FIRST HALF, SECOND HALF AND EQUAL
For each option, explain the supporting evidence and the strongest counterargument. The event is about the total number of goals by BOTH teams in each half, not the performance of one team alone. Compare relevant historical half-by-half patterns and any verifiable matchup factors, but do not assume a past trend will repeat.

Do not invent probability or confidence percentages. If you calculate a historical frequency, show the exact count and sample size and explain that it is descriptive, not a true forecast for this match. Odds are market prices, not guarantees; only compare odds when the market and timestamp are known.

If the data is unreadable, the exact market cannot be verified, the goal split data is missing or contradictory, or the sample is too weak to distinguish the options, return PASS rather than guessing.

E. HANDLE LIVE MATCHES SEPARATELY
If the screenshot is live, read and verify the match minute and score and state when the stats were checked. Use the known goals already scored in each half, but do not treat a partial second half as complete. Check whether the market is still open and whether the screenshot’s odds or stats might be delayed. If the match has ended or the market is settled, say it is too late to predict that market. If the live context is unclear, return PASS.

REQUIRED OUTPUT
Fixture / competition / date:
Pre-match or live; score and minute if visible:
Exact market and settlement rules verified? YES / PARTLY / NO:
Screenshot details read clearly / unclear fields:
Goal split data and sample sizes:
FIRST HALF — evidence for and against:
SECOND HALF — evidence for and against:
EQUAL — evidence for and against:
Final assessment: FIRST HALF / SECOND HALF / EQUAL / PASS:
Main uncertainty / missing information:
Sources and time checked:

Do not recommend a stake or claim that a selection is safe or guaranteed. If the evidence is inadequate, PASS is the correct output.

Why this prompt helps: It requires the model to reconstruct each half’s goals from a half-time score plus final score, or from a reliable goal timeline. It also checks the actual bookmaker’s settlement rules and handles in-play screenshots separately.

Tips for getting better screenshot analysis

  1. Upload a clear screenshot. Keep the match, date, market label and all outcome names visible. If you have historical statistics, upload the half-time scores or goal timelines too.
  2. Check the transcription before analysis. Correct any misread fixture, odds or score. OpenAI says unclear images may lead to less accurate interpretations: ChatGPT Image Inputs FAQ.
  3. Do not use full-time averages alone. Highest Scoring Half depends on how goals are divided between periods. A match ending 2–1 could have more goals in either half or the same number in each, depending on the half-time score.
  4. Confirm the market rules. Bookmakers may specify how stoppage time, extra time, abandoned matches and Equal are settled. Read the rules for the actual market before relying on an analysis.
  5. Accept PASS. No prompt makes football predictable. Treat the answer as uncertain analysis, not a guaranteed way to earn money. Do not chase losses or bet money needed for essentials.

The takeaway: The most reliable prompt is not one that always produces a pick. It is one that checks the market, gets the goal split right, evaluates First Half, Second Half and Equal separately, and admits when the evidence is not sufficient.
