Hello NthnPrsnal,
Preflop: Against 3xBB raises I would even advice to raise 4x his raise rather than 3x while we also are OOP. Plus we wont give him correct odds for set-mining.
As played
Postflop: Not much to add, seems like a nice hand and caught a loose player. Nice hand! Against such players you can even consider betting bigger on each street.
Best Regards.
