stars 25nl

i put a session in tonight on stars 0.1/0.25. I played 483 hands and ran at 16/11/2.5, which is a bit tighter than i normally play but had a win rate of 17ptbb/100 hands which was great. A couple of interesting hands came up. I'll post them without results and you can leave your comments below if you're interested. What do you do and why?
