There is only one chief difference between rules and regulations of Limit Hold’em and No-Limit Hold’em. It can be understood by reading its title only:

Four rounds are played in the Limit Hold’em: before the flop, after the flop, after the Turn and after the River. In the first two rounds of betting only the maximum bet you create is checked at the blinds. The betting is checked at doubles the blinds in the Turn and at the River.

This system helps you to gain more and more benefits from the game. However, a reflective result is there on the strategies of the game to utilize your money.

Bluffing in Limit Hold’em and No-Limit Hold’em:

The method of bluffing is many a times used while playing No-Limit Hold’em. Players use this either to show confidence at the time of flop or most probably for frighten the opponents for folding up their hands. This is in fact a foolish thing to do.

In Limit Hold’em this kind of tricks works by a hair’s breath only. This is because these kinds of tricks are caught by your actions only. You will not be able to increase the amount in the bet by including someone like this. It is not wise on your part. If you are having any ray of hope that you may win the bet then only you can give a call to your opponent.
Like this No-Limit Hold’em is not a game of nuts like Limit Hold’em is.
