Rake

Take a $1/$2 live game. You open A-K from the cutoff, the big blind calls, and the pot builds to $40 after a bet and a call on every street. The house rakes 5 percent before the winner drags it - $2 off the top, well under the cap at that stake, so the cap never kicks in. Lose the hand and rake doesn't touch you; win it and you pay a toll on your own pot. Some rooms run no flop, no drop, so pots that end preflop stay clean. Multiply the cut across every flop you see, and a night you're up $200 on paper comes home $30 lighter.

This is why the best player at a soft table isn't promised a winning night. You're playing eight opponents plus a fixed tax on every contested pot, and the tax bites hardest in loose, action-heavy games where hands run deep - the tables that look juiciest from the rail. It also moves your math. A thin value bet or a speculative gutshot call that reads break-even tips negative once you price in the rake, so position and hand selection matter more than a raw win count suggests.

The beginner mistake is ignoring it: tracking chips won and lost, never subtracting what the house pulled, then wondering why a winning session felt thin - or why a player who breaks even hand-for-hand is quietly a loser.
