Reading one
Illustrative example: an alert says Team A +6.5, playable to +5. If your book offers +6.5 or +6, you're inside the number. At +5 you're right at the limit. At +4.5 the market has moved past it, and the bet no longer clears the bar it was released at.
For totals it works the same way in the direction of the bet: Under 141.5, playable to 140 means 141.5, 141 and 140 are fine; 139.5 is a pass.
Price counts too
A line can stay put while the price changes. +6 at −125 is not the same bet as +6 at −105. If the price is much worse than the one posted, treat it like a worse line. The line checker takes both into account.
Why passing matters
Chasing a number that has moved is one of the most common ways bettors give back an edge. Most bettors remember the pass that would have won; few remember the dozens of moved numbers they correctly skipped. Over a season, the discipline is what holds up.
When you're late
- Check the current line and price before anything else.
- Shop other books: one may still be inside the number (line shopping).
- If none are, pass. There will be another bet.
