Hello everyone, this is my first time posting on RIO. Kindly forgive me if I am posting a very standard spot. I've been playing for many years but exclusively at my soft home games, which I beat rather comfortably. But I have struggles against unknown players who I have no information to use against. Hopefully some of you can give me some advice on how to play more optimally without information.

Villain is a new player at our home game, brought by one of our regulars. I have a total of maybe 60 mins played with him, not much reads. He didn't look like a very experienced player but definitely not a complete newbie either.

Like I have mentioned, kindly forgive me if this is a very straightforward situation for you guys, I just want to know what you think of these spots without reads.
