Hi, when talking about adjusting to stack sizes in this video, Owen says that when there are a lot of reshove stacks behind you should be playing a "Tight Blocker Range".

I'm not 100% sure what that means, although I have a rough idea. I think I over adjust in these spots and end up being too tight. For example, lets say I am in CO with 40bb, and both the SB and BB have 15-20bb.

My original starting range in this spot would be a 33% range:

AA-22,AKs-A2s,KQs-K2s,QJs-Q7s,JTs-J7s,T9s-T7s,98s-97s,87s-86s,76s,65s,54s,AKo-A5o,KQo-K9o,QJo-QTo,JTo

What I might actually play in this situation would be about 20%:

AA-22,AKs-A2s,KQs-K9s,QJs-QTs,JTs,T9s,98s,87s,AKo-A9o,KQo-KTo

I might even drop the lower AXs and pocket pairs if both blinds are at 15bb or less.

Is this too big a reduction?
