I feel a smile because I know these kind of situations are what keep the fish staying as fish.
your fold was a good fold because majority of times you are not flopping even a half-decent hand especially if opponents represented strength in their hands. Also consider what opponents have and would call you with, they can even badbeat yoru flush iwth fullhouse cooler on turn or river, never underestimate the power of folding.
A good fold is good and a weak fold is weak. Don't be weak in fear, be weak to keep your cash. Don't 'not fold' to catch the flop, don't fold to have the opponentnot hit the flop hard enougha nd bully them away form the hand.
I think like a loose player because bluffing is an essential tool in my arsenal. If I folded and flop the nuts, it means nothing to me at all. It was a good fold and I won't let that turn me into a fish and doubt my majority-win playstyle. One step down is severe in your evolution as a poker player you must stay vigilant in your fervour to only improve yoru playstyle and never ever let severe minority-occuring scenarios alter your playstyle in another direction.
