Range pre-flop

[PHAkash]

When it comes to studying pre-flop ranges, we don't study all possible stack sizes (1bb, 2bb, 3bb, 17bb, 18bb, etc.), mainly for three reasons:
1. Time and memory savings — It would be impossible to memorize and apply intervals for each blind size in practice.
2. Behavioral blocks — The changes change significantly between certain stack sizes (blocks), but within the same range, they are very similar. For example: tracks from 27bb to 30bb hardly change; from 15bb to 30bb, it changed significantly.
3. Common Situations — Some stack sizes are more common in MTT and exclude more complex decisions.

Most of my study in stack sizes were at the 100+, 50-100, 20 and 10. If you can get those down then you can venture out into more and more.

I would say 10-20BB is where you can make the best edge over other tournament players, because mid-game people are often far too tight or too light.

Dont focus so much on segregating studying by stack depth. It usually make more sense to divide it by topic. Like how to play SRP IP vs BB. And then just compare how it shifts when you change stack sizes. Which flops are played similarly at 20bb and 50bb at CO vs BB? Which are played totally different? Etc. And for preflop that works too. Compare how 3betting shifts BB vs BTN from 20bb deep, 30bb, 40bb, 50bb... you can go through all the stacksizes and think about why the strategy looks like it looks.
