I think Party 2/4 is a bit looser than 1/2 this is because there is no 6 max tables at 2/4. At 1/2 you can play more agressive and your semi bluffs will force players to fold.

At 2/4 your semi bluffs and agressiv play has less value because other players will call you down with any flopped small pair.

I think a better strategy at 2/4 is to limp more with 55-88 from utg. Suitet connectors like 89s if min 2 players are in before you. If you dont catch a hand or a big draw at the flop just save the money and fold. When you hit somthing, just pump it up, its wery profitable.
