Hi everyone, I've recently started playing again after having a 1.5 year break. Last time I played I multi tabled micro stakes and got bored. This time I've moved up a bit in stakes, play only one table at a time and play almost exclusively short handed. I feel it improves my game a lot when I can concentrate on one table to improve reads and post flop play. However, I know I've still got tons to learn about post flop play. These two recent hands I have a hard time deciding how to play and if I play them correctly. Any advice is appreciated!

Villain just arrived at the table, played like one orbit. This is the third hand in a row I raise preflop, so he's seen me raise like 3 hands out of 5.

In this hand, my read on villain is that he limps alot of hands preflop and generally plays passive postflop. I've played TAGG by the book. Comments on my preflop complete is also appreciated here.
