Chowaha poker
A hold 'em variant invented in a private game by RGPer Mike
Chow, and popularized at BARGE, in which each player gets two
downcards, the dealer flops nine cards, arranged in three rows
of three, then turns two cards vertically at the ends of the
"corridors" between the preceding rows, and rivers
one card in the middle and to the right of the two, the whole
arrangement forming a large arrow-like structure. Players form
their best five-card hand using their two plus any three cards
from the four possible five-card board
combinations: top row of three plus top card of two plus river
card, bottom row of three plus bottom card of two plus river
card, middle row of three plus either one of the two turn cards
plus river card.
