As a general point maybe I'd raise a little more preflop ($30?) since there are so many limpers and you're out of position. Probably wouldn't have made much difference in this particular hand.
Other than look it looks totally fine in my opinion.
My view, too.
But with "4 or 5 limpers" I'd have Raised a little more pre, maybe $30. I'm happy to take the dead money, tbh. If we don't see a flop, we are usually 100% fave (approx) to win the hand, & we never get sucked-out.....
It's a shocking call by him pre-flop, so be pleased, make notes on him, & find his table every time, he just can't play. A-6 indeed! That's a Flushy play, but not one for grown-ups.
