My bread cuts doesn't expand the way I like
To encourage oven spring, you want to have a steamy environment in your oven for the first 5-10 minutes of the baking period.  This will delay the setting of the crust, allowing better expansion.

Good slashing can also help, allowing the dough to expand where it has not formed a tight net of gluten strands holding the loaf closely together.  You can see some examples of the effect of different slash patterns at:
