This week you’ll be practicing a very common situation in Small Stakes cash games. A primary feature of Small Stakes games is that larger open-raise sizes are typical. For example, in a local $1-2 home game, the open raise will be often $10 or more.
In this spot, you open-raise to this larger 5BB raise size preflop from Middle Position and after the opponent reraises to 15BBs on the Button you call.
Given that Villain is the last preflop aggressor, their range will typically be stronger on most flops.
