Choosing which sportsbooks to use based on their margin structure, winner-friendliness, and long-term viability for a profitable bettor.

Sharp bettors deliberately place recreational-looking bets at square books to maintain access. Deposit with credit card, bet random accumulators early, save sharp picks for discount books. This is a meta-strategy that only matters once you're actually winning — and it's invisible to beginners because they never face the problem it solves.
The standard affiliate model pays tipsters a share of their subscribers' LOSSES to the bookmaker. The worse your tips, the more affiliate revenue you earn. When evaluating betting advice, check whether the revenue model profits from your success or your failure.
