Okay so preflop he raised 3BB which I thought could mean he has a premium hand and if everyone else folds the SPR is healthy 14 for my drawing hand. Maybe this is a little early for 78s?
On the flop I figured I'd semibluff because I figured the implied odds would be less if I check called my draw. Plus I got a gutshot + flush draw so I dont mind building a big pot. When he check raised I figured he probably has an over pair or 2 pair etc so if I reraise he will shove. Plus if I smooth call and hit my draw on the turn he could end up commiting and I could cream off the rest of his stack. [img]/images/graemlins/grin.gif[/img]
What do you think he had btw?
