Against weak loose players you should make a number of adjustments to your game but be aware these adjustments against solid LAGs would see you ripped apart very quickly indeed. The first is to play them at their own game and loose up your preflop play when this player has already entered the pot. Do not go completely mad and start playing 7s3h but if they have limped in you can safely play more speculative
hands than you usually would such as 9c8d, 7d5c and small unsuited aces. If they come in for a raise, particularly if they raise a lot of hands you can probably call with hands as weak as Qd10d, AsJc and all suited connectors and one-gapped suited connectors.
You should also start to value bet weaker hands such as top pair simply because they will pay you off handsomely. Against a tough LAG you are unlikely to win a hand at showdown with just top pair because if they call bets on all three streets then they are usually strong enough to beat top pair. But weak LAGs will often call opponents down with top pair and no kicker or draw to a hand and hit a weak pair and still call you down with it.
Finally, you should try to
bluff these players much less than you would a tough player or a tighter player simply for the fact you are likely to get called by a weird and wonderful array of hands by a weak LAG. Do not stop
bluffing completely otherwise even weak players will be able to read you easily and exploit you but try to keep the big daring bluffs for a more suitable candidate.
True LAG players are a complete nightmare to play against, especially if they have position on you but flip the coin and have position on a weak loose player and you stand a chance of stacking them on numerous times before they either run out of money or quit the table. Isolate them, play as many pots as you can with them and get your hands on their
bankroll before someone else does.
Hope I helped you.
gl, see you at the tables.
