The Betting Checklist: 5 Questions Before Every Bet

Professional bettors don't wing it. They have a process — a set of questions they ask before every single bet. It takes 30 seconds, and it filters out the impulsive, emotional, and -EV bets that destroy bankrolls.

Here are the five questions. If any answer is no, you don't place the bet. No exceptions.

1. Is this bet +EV?

Have you calculated (or at least reasonably estimated) the implied probability from the odds and compared it to your estimated true probability? Is your estimate higher than what the odds imply? If you can't articulate why this bet is +EV in one sentence, it isn't — or you haven't done the work.

2. Am I within my unit size?

Is this bet exactly 1 unit (1% of your purse)? If you're tempted to bet more because you're "really confident," that's your emotions talking, not your analysis. Confidence is not edge. Stick to 1 unit.

3. Have I shopped for the best line?

Have you checked at least 2-3 sportsbooks for the best odds? Line shopping is free money. A half-point or a few cents of better odds on every bet compounds into thousands over a year.

4. Am I betting on data or emotion?

Be brutally honest. Are you betting because your research identified +EV? Or because your team is playing, the game is on TV, you're chasing a loss, you're bored, or a Twitter account told you it was a lock? If the reason isn't data-driven, close the app.

5. If the game were tomorrow instead of tonight, would I still make this bet?

This question catches time-pressure and FOMO bets. If the answer is "I'm only betting because the game starts in 20 minutes" — that's not analysis, that's urgency. +EV bets are just as +EV tomorrow. If you'd pass on this bet without the time pressure, pass on it now.

Using the checklist

Bookmark this page. Screenshot the five questions. Tape them next to your computer. Whatever works — the point is to run through them every single time. The checklist doesn't make you a winning bettor by itself. But it prevents the specific mistakes that make losing bettors: impulse bets, oversized bets, unresearched bets, and emotional bets.

Over time, the checklist becomes automatic. You'll internalize the questions and catch yourself before bad bets without consciously running through the list. That's when the system is working.
