provides, assumes all players who would act before the out of turn player would not exceed the amount of the out-of-turn bet. This may not be the case, and would result in the player having to bet twice to cover preceding raises, which would cause confusion. Cards A player is never required to expose their concealed cards when folding or if all others have folded; this is only required at the showdown. Many casinos and public cardrooms using a house dealer require players to protect their hands. This is done either by holding the cards or, if they are on the table, by placing a chip or other object on top. Unprotected hands in such situations are generally considered folded and are mucked by the dealer when action reaches the player. This can spark heated controversy, and is rarely done in private games. The style of game generally determines whether players should hold face-down cards in their hands or leave them on the table. Holding "hole" cards allows players to view them more quickly and thus speeds up gameplay, but spectators watching over a player's shoulder can communicate the strength of that hand to other players, even unintentionally. Unwary players can hold their hand such that a "rubbernecker" in an adjacent seat can sneak a peek at the cards. Lastly, given the correct light and angles, players wearing glasses can inadvertently show their opponents their hole cards through the reflection in their glasses. Thus for most poker variants involving a combination of faceup and facedown cards (most variants of stud and community are dealt in this manner), the standard method is to keep hole cards face-down on the table except when it is that player's turn to act. 5 card draw is generally played with hands held by the players at all times.

Then, if opening or cold calling, the player may exchange a large chip for its full equivalent value out of the pot before placing their bet, or if over-calling may place the chip (announcing that they are calling or raising a lesser amount) and remove the change from their own bet for the round. Normally, if a player places one oversized chip in the pot without explicitly voicing intention while facing a bet,
