I dont play FR much, but if effective stacks are around 100 BBs I would flat call here with small PPs (JJ-22). With very aggressive players to act, I could fold 88-22 and call JJ-99.

QQ-AA I would isolate the player with a 3x raise, if he 4 bets all In I would call it assuming that he is a standard micro-limit donkey (they love to do this with AQ+).
