This is a feeling I've been having too.
All the limped pots and speculative hands that can be played in a free roll will have to be cut out and played differently when moving up.
All the strong hands but marginal hands (KTs, KJs, KQs, ATs etc) I would normally raise with I often have to limp with in a multiway pot because calling will just build a big pot and my opponents are never folding anything.
I've been eating sh!t a lot lately because I've been adjusting my calling range when there are crazy players at the table. I don't think this is incorrect either. It introduces much more variance which is frustrating, but I think it's right. Yesterday for example a guy was played a VPIP/PFR of 90/85 and just moving in almost every hand. I had AJo and he shoved under the gun for 50BB. I called, he showed T4o and hit a 4 and I was out. But I think it's right to adjust your calling range and take a stand against crazy opposition. You will be a favourite to take their stack before someone else does, then you'll have a big stack to play a more normal brand of poker when the crazy villain is KO'd. It does mean you'll be knocked out more often though, so either adjust your calling range and live with the results, or play tighter, give up the spots for huge double and triple ups and wait for better spots. Even if you do, though, you'll be knocked out of free rolls more often than other tournaments purely because of the nature of the players.
