^^ Is it worth it for me to call or shove here? Or should I muck?

Next hand at a diff table and diff villain. He is a solid tag. Hes a regular. 5 min ago, he raises pf from dealer position, and I 3 bet him from the big blind. He folds and says "do it again"

^^Does villain value bet with AQ/AJ? The way I played it, it looks like a flush draw, so I thought he might be trying to get value from AQ/AJ. Do we call here? If we have AQ/AJ, do we call? <font color="red"> </font> <font color="red"> </font> <font color="red"> </font> <font class="small">Code:</font><hr /><pre> </pre><hr /> <font color="red"> </font>
