Definition of nh
Nh means "Nice Hand", meaning "beautiful hand". You can often read "nh" in online chat rooms at poker. It is a way to let a player know that he or she has played well. You can also use "nh" to comfort a recreational player who has made a questionable game (after which you will probably read inappropriate comments about him or her by some players). Rather than throwing a "you can't play fish", use the polite "nh, well done". When you compliment a player by writing "nh", most of the time his answer will be "ty" for "Thank you" (thank you).
Etiquette at poker" tables
If you often play poker online, it will be very important for you to have the image of a courteous player. Don't be too conspicuous, always be diplomatic. It avoids putting the spotlight on you. If you're too flamboyant and people start to notice that you're a big winner, maybe you'll scare off the competition. If you're not diplomatic in the chat room, maybe you'll get your chat room privileges removed, which is a valuable tool when playing poker online.
