I stay pretty darn quite at the table. The only time I want to say something catty is when I get sucked out on bad or take offense to a big loss.
9 times out of 10, when I review later there was something I did wrong during the hand to lose the pot. Always something I could have done differently at some point in the hand to win the most or lose the least and that means I have an opportunity to get better next time. Nothing good can come from me mouthing off to the loss, so I will make a determined effort not to let this happen ever again!
Now that I have said that, why should I mouth off after a win?! It'll never happen either, for many reasons that are stated here, but also because it is not my personality at the table. Do everyone the favor and save the story for the forum later. Come on here after the winning is done and tell us how poorly they played and how well you punked nonamedonk in whatever situation. Tell us how you thought it would've been hilarious to berate them saying, well at least you HAD the nuts, or whatever it is.
To us, it will be funny. But in the actual situation, not so much. It is just my opinion, but save the glory for your boys after the fact.
With regards to Deb's early comments:
tells (like enemies) accumulate during the game. Your opponents do not stop looking for your tells at the showdown. A good opponent will remember how you played the hand, what were your actions/behaviors/mannerisms when you had a winning hand vs a losing hand at the showdown. They will tie the pieces together to build a profile that helps them make decisions against you later! SO even though you think the hand is over, you are still being watched and evaluated. The talkative, taunty player who gets quite during or after a
bluff... the nervous sigh of relief or that cheesy can't-help-myself grin one gives after a successful bluff...all of that goes in you file.
Win quietly and win often.
