Player to be carded — what it means
"To be carded" is a binary market — will the player pick up a booking — and it's where the single most mispriced factor in football betting lives: the referee. SharpXI builds a booking probability that puts the official front and centre.
How SharpXI models it
We take the player's recency-weighted booking rate, shrink it for small samples, then multiply by the referee's card tendency and an opponent factor, plus a modest derby multiplier where warranted. A Poisson booking model gives P(at least one card); the price is compared as offered — cards are quoted one side only, so the margin stays in it — and isotonic calibration keeps the tail honest.

Where the value tends to sit
Bookmakers price cards mostly off the player and the fixture; strict referees are systematically under-weighted. A combative midfielder under a card-happy official is the archetypal edge.

Frequently asked
What does "player to be carded" mean?
It is a bet on one player picking up a card in the match — yellow or red, either one settles it. Some books call the same thing "player to be booked". It is a yes/no market on that single player, and it has nothing to do with how many cards the match produces in total.
What does 1+ cards mean?
The same bet, written as a line: one or more cards for that player. The "1+" is there because card markets share a format with counting markets like shots and fouls, where 2+ and 3+ are real options. For a single player's cards there is effectively only the 1+ line, which is why it reads oddly next to the others.
Does a red card count as two cards?
Not for this market, because the question cannot come up: the bet asks whether the player is carded at all, and one card already settles it. Whether a red counts once or twice matters in TOTAL card markets on the match or a team, where books count differently and the rules are worth reading before you stake.
Is there a 2+ cards market for a player?
No — a player being carded twice means a red, which is rare and priced differently. SharpXI models the honest market: whether the player is carded at all.
Why does the referee matter so much for cards?
Card counts vary far more by referee than most punters assume, and the market is slow to fully price it. SharpXI uses each referee's booking tendency directly.
