A lot of the material I've seen regarding 4 and 5b pots says that optimal play is to always shove once it gets to a 5b. In this spot, v 4b's me to $2.55. Is my shove the correct play or is there a 6b sizing I can use in spots like this that maximizes my value more? I've been in similar spots 180+bb deep and I'm not sure how to handle it.
