Glossary of Poker Terms - I

I

ignorant end, idiot end

In flop games, a player drawing to, or even flopping, a straight with undercards to the flop has the idiot end of it. A player with 8-9 betting on a flop of A-T-J puts himself at great risk, because many of the cards that complete his straight give credible opponents higher ones.

implied pot odds, implied odds

See main article: implied pot odds.

improve

To achieve a better hand than one currently holds by adding or exchanging cards as provided in the rules of the game being played. I didn't think Paula was bluffing, so I decided not to call unless I improved on the draw.

inside straight

See inside straight draw. Also "belly buster", "gutshot". Compare to outside straight draw.

in position, IP

A player is said to be in position, if the player is last to act on the flop, turn and river betting rounds. Compare to out of position.

insurance

A "business" deal in which players agree to split or reduce a pot (roughly in proportion to the chances of each of them winning) with more cards to come rather than playing out the hand, or else a deal where one player makes a side bet against himself with a third party to hedge against a large loss.

in the middle

1. In a game with multiple blinds, an incoming player may sometimes be allowed to post the blinds "in the middle" (that is, out of their normal order) rather than having to wait for them to pass.
2. A player being whipsawed is said to be "in the middle".

in the money

To finish high enough in a poker tournament to win prize money. Also "ITM".

in turn

A player, or an action, is said to be in turn if that player is expected to act next under the rules. Jerry said "check" while he was in turn, so he's not allowed to raise.

irregular declaration

An action taken by a player in turn that is not a straightforward declaration of intent, but that is reasonably interpreted as an action by other players, such as pointing a thumb up to signify "raise". House rules or dealer discretion may determine when such actions are meaningful and/or binding.

irregularity

Any of a number of abnormal conditions in play, such as unexpectedly exposed cards, that may call for corrective action. See Public cardroom rules.

isolation
