Surface matters
Clay-court grinders vs. serve-bots on grass produce wildly different probabilities than the same matchup on hard courts. Bet H2H records by surface, not overall.
Live break points
Sportsbooks frequently overreact when a player is broken. A 30% favorite who just lost serve isn't a 50/50 — they're often still 38-42%.
Retirement risk
Read each book's retirement-rule fine print. Some void on retirement; some pay if your player wins one set; etc.
Avoid
Slam outright futures on injury-prone stars. Locking up money on someone with a chronic back is bad value.
