Our weekly game has been running for about 15 years. We started with nickels, dimes and quarters in a dealers choice that was usually hold'em or stud. A lot has changed over the years. Some has been natural, like replacing change with chips. Like increasing chip values to 50 cents and a dollar. Like adding to our game repertoire. Like having the dealer ante 5 chips to eliminate the "somebodies always light" annoyance.
But some of the changes were by design and came after some group discussion. One crafted change was to introduce the mixed game deal. This is patterned after the old HORSE tournaments, where each time the game changed, it was dealt all the way around the table. In the mixed game approach you can get a little game rhythm going, a little more strategic in your thinking because you stay with a game variation a little while. We still play dealer's choice but alternate the format weekly, which keeps the regular get together fresher.
Another calculated change was to move from a flat bet structure to a spread limit. Now a player can bet or raise anywhere from 1-5 chips at anytime. It's hard to defend your hand, or build a pot strategically when all you can do is bet or raise a chip.
