One thing is very clear, and that all those strategies were already in play.
How can that be if all blocs are now 1 MB ? How can there be strategies in place with orphaning blocs with sizes you do not like if they are all equal to the maximum size ?
Size of blocks is the not the only way to play those sort of games. Withholding blocks with a delay is equivalent (i.e. a form of selfish mining). I am not going to cover all the details and scenarios now and relate it all to your discombobulated post. Sorry I've got higher priority work to do, than arguing with people who think they are making a point but don't realize they are not. I suggest you study all the research first, before attempting to get into a detailed discussion with me. I did (or at least much of it).
