He's been betting real small for such a connected board. Who likes a shove on the river?
And speaking of betting real small, I'm not 100% on my play in earlier streets. I've been getting decent+ odds over and over lately but I cringe every time I play a draw so passively. Being OOP adds to the WTF factor.
