Bava Batra 41 - Rosh Chodesh Av - August 5, 1 Av

Today's daf is sponsored by Marcia Baum in loving memory of her father, Sam Baum, on his 21st yahrzeit. "Dad was a larger-than-life individual whose acts of chesed and tzedaka are remembered to this day. He was a proud Jew, lover of Israel, and a proud American. He is sorely missed by all who knew him." For a chazaka of presumptive status to be effective, the possessor must bring a claim of how the land came into their possession. What would/would not be considered an effective claim? Why doesn't the court advise the possessor on a possible claim the possessor could make? In two stories, rabbis claimed they had a chazaka but were ruled against as the chazaka was not created properly. In a third story relating to chazaka, there is a debate among the rabbis about whether or not this was effective. If three different people owned the land for the three years of chazaka, each claimed to have purchased it from the previous owner, can the third one claim to have a chazaka on the land after the third year?
