Show your cards? Sorry, long one again.

If I’m understanding you correctly, by not re-raising pre-flop you are allowing four players to see the flop for two small bets. I’d re-raise pre-flop every time. Don’t let low pocket pairs get in there cheap and turn into sets.

Post flop, I’m fine with the call, especially heads up, as you are setting him up for the larger re-raise on the turn, just as you did.

Meanwhile, after the win, tossing your cards into the muck is exactly the right play. If an opponent misreads you, there’s no need to correct him – you want to exploit that. You are not there to prove to anyone that you are a ‘better’ player than they are. You are there to make money from them.
