One hand from yesterday.
It's 2/5 and we are 150bbs effective.
OI straddle to $10, MP who is reggy makes it $30 as he's been doing often and old guy playing almost every pot but playing passivley calls OTB. I flick it in from the straddle w/

.
This fine or a great spot to 3b to isolate the old guy?Flop is

I check, reg bets $60, old guy calls quickly and I call.
I'm pretty sure I can only ever call here right?Turn is

and I lead for $110, guy calls pretty quickly.
Thoughts? I think it has its pro's and con's but I def don't like c/c two streets here so I think leading/c/f >>>>> c/c. But not sure if leading/c/f.
River is
we?
