re: Poker & Minimum Number of Hands to Play to be Profitable?
Tightness and aggressiveness are not connected. They are seperate parameters with their own measurement.
Tightness or looseness refers to the number of hands played, or the vpip of a player.
Aggressiveness is how often the player is betting at the pot or raising. This applies both preflop and postflop.
A player who's vpip/pfr/AF go 15/3/5 would be tight/passive preflop, aggressive postflop. Just change the AF to 1.5 or something and now he's tight/passive preflop, passive postflop.
Players can beither either tight/loose and either passive/aggressive with any combination of those two, preflop and postflop each it's own category.
Candy, it sounds like you're playing a live game. You're correct that if you wait for QQ-AA or AK, that people are going to notice you've been doing nothing but fold for hours, and they'll only play with you if they too hold a powerful hand.
Your hand range is going to fluctuate based on the play of the table and your position. If the table is loose passive, as many lower limit live tables are, then you can definitely play any pp profitably from any postion. 22-JJ are mainly for hitting sets, and QQ-AA are truly powerful hands.
With the smaller pp's you're looking to take a cheap flop and hit it hard. You can also play AK-AQ and KQs from any position. This makes up 8.6% of hands.
As you get into later position, and you know that you can limp behind other limpers, you can start adding in:
suited connectors: QJs-54s - 2.4%
suited gappers: QTs-64s - 2.1%
I'd add in AJs, ATs - 0.6%
KJs, KTs - 0.6%
AJo, KQo - 1.8%
This makes up 16.1% of all hands. It's still pretty tight, but you're playing enough hands that people can't just put you on a particular holding. Keep in mind that you aren't playing all of these from every position either, so in reality, you're probably only going to be playing something like 10% of your hands.
I'm not sure what you mean by "big bet poker". But I'm inclined to believe you mean that you're betting often.
This strategy applies to a table that is more weak/tight than loose passive. If players are willing to call bets with light holdings, then you shouldn't be betting at them unless you have a strong hand. By the way, hands like straight over straight are just coolers, you're going to lose a lot there, and that's fine.
If players are folding to cbets, and are hesitatant to go on in a hand without a strong holding, then you should start raising more with the hands you'd be limping with at a loose table. You want to ideally get heads up on the flop with position against these players. Then you'll cbet the flop, and likely take it down.
If you could expand on what you mean by "big bet poker" maybe I could give you a better explanation of how to approach the style.
