You're a liar, you nit you
Not at all. I am a old-school nit. But I find good occasion to limp for a number of reasons.
One thing I have found over 20+ years of playing poker, you can not make blanket statements such as winning players can not limp. The truth is just about any style can win, as long as the person knows how to play against 'type'. While you may teach beginning players a certain pathway to a winning player and be right to do so, actual winning players encompass all different styles.
So yes, probably nothing wrong with telling new players they shouldn't limp, but to say anyone who limps is a donkey is most likely an incorrect statement. But ya'll can label me donkey when we are playing...I will not take offense.
For the most part I will limp more often against aggressive players, and raise more often against passive players.
Even the statement, people should not berate donkeys is overall the proper statement for the majority of people, but it has its place in strategy. If you are a nit player, it can be used to slow down an aggressive donk who you want to raise less for some reason, it can be used to put players on tilt. For me, it can be used so that you make people either respect your raises and they fold, or disrespect you and want to reraise against you. Talk affects people, and can make players change the way they play for the better of your game sometimes. It generally makes people look you up, and if a google shows somehow you have weak stats, those players will be raising you, if it shows you are strong, they will be folding more against you.
The only blanket statement I make is...you are 100% donkey if you use a stalling strategy every hand when you play an MTT.
