Beyond the clear aesthetic benefits of bigger stacks, the color-up obsession has technical drawbacks as well. Playing 1500bb with no 100s in play forces players to 2x, 2.33x, or 2.67x. Almost no one would choose these sizes if unrestricted. Forcing such limited choices in terms of sizing hurts the ability to he precise way beyond what is reasonable. Blind levels should not be amended to fit a color up schedule. Chips should only be taken out of play once they are no longer needed while using a standard 1:2 sb to bb ratio. You should always be able to bet in increments that represent at most 10% of 1 bb with the exception of the earliest levels. This would mean that 100s come out once entering 5k bb 500s come out after 10k bb is complete. 1ks in play until 50k bb is complete. We shouldn't sacrifice bet size options for the ease of the TD (within reason) The exception is in turbo events where all ins occur frequently. Aggressive color up is more necessary when stacks are needed to be counted regularly. In an event like the WSOP Main, where all ins are quite rare even as far along as day 5/6 , having larger stacks is a no brainer.
