Refers to a player in middle position MP who, on the river with a rainbow board (four cards of different suits, no flush draw possible), chooses to only flat call rather than raise.

Term Breakdown
- MP (Middle Position): Middle position, typically the third to act at a six-handed table, or fourth to sixth at a nine-handed table. This position is neither early nor late, requiring a balance of value bets and bluffs.
- River: The final community card, determining the ultimate hand strength.
- Flat Call: To merely call a bet, without raising or folding. Often used to avoid bloating the pot or to induce a bluff from the opponent.
- Rainbow: A board texture where all community cards are of different suits. Here, it extends to the river where all four cards are of different suits, meaning no flush draw is possible, simplifying decision-making.
Strategic Context
This term typically describes a scenario where: a player in middle position holds a medium-strength hand (e.g., top pair with a weak kicker), the river completes a rainbow board, and an opponent bets. The player chooses to flat call for reasons including:
- Pot control: Avoiding excessive chips if re-raised.
- Bluff induction: If the opponent might continue bluffing out of position, flat calling keeps their bluffing range intact.
- Value extraction: Flat calling prevents the opponent from folding a worse hand; if the opponent has a strong hand, it minimizes losses.
Notes
This term is not a standard poker term but a descriptive combination for a specific situation. In actual play, decisions should be based on opponent tendencies, bet sizing, stack depth, etc., not mechanically applied.
Related Strategy
A flat-calling range on a rainbow river typically includes medium-strength made hands (e.g., one pair, two pair) and some bluff-catchers (e.g., top pair weak kicker). Avoid flat calling with the nuts to not miss value.
