Some kind of interesting hands here, wonder what the world thinks, these two both link nicely into each other.
1)
4 handed $10/$20/$40
I open to $140 on the button with

two of the blinds call.
Flop ($430)

chk, chk I bet $220, fold, call
Turn ($870)

Chk, I bet $520, he doesn't skip a heartbeat in raising to $1600.
I've played with this guy a decent amount on my last trip here, he is about 45 and plays quite solidly, he made a kind of bizarre hero call vs me the previous day so it's fair to say he thinks I'm quite aggro/will barrel off and will expect a pretty wide open from the button. HE doesn't strike me as the sort of player to do much in the way of bluffing, I remember trying to make some hero calls vs him in the last trip but they all failed.
He is playing $3.1k behind the turn raise, I cover. Thoughts?
Now hand 2) vs the same player.
$10/$20/$40 9handed with a $80 straddle.
folds to the same guy who makes it $400. I flat in the $40 with

the straddle calls as well (very loose italian man)
flop ($1,230)

He Bets $2,500 with $3,000 back, we cover.
We will have Italian loonball behind.
What are you doing?
