call the first

decent chance youre behind in the first one, but he could easily have a worse 3 and is vbetting (you say he likes to make thin vbets). i would believe him that the Q didnt hit him. i think he puts you on something like AQ that raised his weak looking bet and is trying to get a lot of value on the river, so he is in turn trying to get big value out of his hand. i dont think hes lying that the queen didnt help him, and it seems like he has a 3 more than a boat because he would probably repop pre or fold more often than not with the possible boat hands.

2nd hand with the way he plays its very tough, but i put him squarely on QQ and not a flush. i suppose this type of player can float you twice and would definitely do it unpredictably, so i think calling is eh, but folding is probably better based on the fact that he acted a bit on the turn, called the flop c/r and made a solid, callable river bet when it doesnt seem like he would have the flush.
