Some things get lost when you can't listen to inflection. So I have no doubt that when I lose a big pot, fold to a wet board, or get knocked out of a tournament, some people will think I'm being sarcastic when I send my congratulations to the guy that took my chips and wish the remaining players good luck.
But I'm one of those guys who really means it.
Because every hand I face, win or lose, is another card in the file. Another situation I've seen and reacted to. And another chance to figure out what I did right, and more importantly what I did wrong. Should I have called instead of 4-betting the pocket aces? Did my slow play when I flopped two pair allow the villain to make his flush? Why did I lock into a plan before seeing the river card, and why didn't I recognize the straight draw on the board? Would I have been better served checking the river after a check-check turn instead of floating a min-bet? How often is he limp-calling a pre-flop raise out of position suited 1-gappers? How often has that play worked? Why the *bleep* is that guy's Big Blind calling a 3x raise from the button or cutoff with any two cards?  How often has this play bitten me in the... you get the picture.
If nothing else, those "bad beats" serve to remind me that more than half of the other guy's hand is still in the deck.
So, dude playing 72o out of position who turned a flush in the suit I didn't have covered, nice hand; I let you in by slow-playing suited AJ.
Well played, guy whose baby suited connectors flopped trips to beat my pocket Kings; because you still got my money in the pot.
Nice hand, gal who filled her gut-shot straight on the river; I didn't even see the possibility of a straight there.
Good luck... and I hope to see you in the next tournament; after I learn from this, of course.
