3! the flop and barrel all streets....
I'm assuming the cbet on the flop is the source of embarrassment here?
I can see why you'd be tempted to CB this, especially since two of your callers were in the blinds and might be calling ATC.
No beratements here--I can see myself instabetting and then being like ,"Oh, wait. I'm totally behind or facing about 25 outs. Whoops."
Its ok. You're still good at poker.
