given the flop structure and villain is loose aggressive/aggressive based on about 300 hands i felt i had to insanely protect my hand after a cold call on the flop... especially after the turn... i instantly put him on some kind of ten or clubs...

am i losing out on serious money by betting out this much and committing both of us to the pot at the turn or should i have just potted the pot
