BTN is unknown, Asian, late 30s, came to the table with some $100 chips and some $20 chips, usually means they are either coming from the dark side where black jack is played or deeper stack game. Very small sample of maybe two orbits, he showed some aggression, but hasn't really reached show down. Doesn't appear to crazy. I am not sure what hands he calls $80 with preflop. I mean if he calls $80 preflop and has AJ or 87s hand, I gotta pay him off right? Oh side note, he called the $40 pretty quickly on the flop, which is a live tell for not having a very strong hand. It's not always accurate though.

T9s, QTs, 87s, 98s, A10s, KQs, 99, ... Struggling to give BTN a range of hands here. Felt like a strong hand here, but given 3:1 odds and the fact he put in 16bb preflop, I am not sure how much value an SC brings in a bloated pot.
