Curveball hand - good time to show?

[partygirluk]

$15 SNG. I don't normally do this thing, but I fancied mixing things up. The flop was nice. Any advice on how you think I could have extracted more is welcome. I showed my hand at the end, as I am not going to try this move again. Wise move?

i don't think so. not me. i'd prefer players to think i'm tight; it helps me make steals. i'm going to have to steal pots a lot more than i'm going to have monsters; why make other players want to call me?

it sucks when everyone folds to your AA, but sucks worse when they suck out on you when you get two callers with top pair mediocre kicker.

especially in a stt, i can't see this paying off too often.

nice flop though.
