Found this thread through a poker peer.
3bet here is standard against: short stacks, loose passive, bad LAG, good LAG, and loose TAG. Against a tight-passive player, they are tight, but they are likely to call with QQ/AK/JJ OOP, so I'd 3bet them as well. Against a tight-TAG or TAG, they may 4bet or fold OOP, so stay polarized in this spot, and don't 3bet QQ/AK unless you will 5bet them. Also, an advantage of calling is that you can let weak players into the hand, plus can call/4bet over a squeeze. Against a Tight TAG they are more likely to 4bet or fold OOP and may not 4bet QQ/AK/Bluff in this spot so I wouldn't 3bet against them here. Against a TAG it's close, but because people will often call a 3bet OOP at 25NL plus this guy may actually be 4betting QQ+/AK/bluffs, a 3bet is fine here.
I like a $3 3bet here, you want him to call with QQ/JJ/TT/AK/AQ and check-fold the flop, although you can make it $3.35 if he calls more often, and a big 3bet may make him go into 4bet or fold mode. You can also 3bet bluff AJo/KQo/64s/K7s here, and a smaller 3bet size is easier to balance with that.
I guess $8-$8.50 is fine for his 4bet. If you make it too big you reduce the number of calls if you have a value hand, and put in too much money if you are bluffing. If you make it too big, you may accidentally end up being priced in if you 4bet OOP with something like AJ/KQ/77.
The guy seems kinda LAGgy enough that you can 5bet all-in here. He can have QQ/AK and maybe bluffs/JJ in his range. I wouldn't call the 4bet because he could have AK and miss, or have JJ and get scared off postflop, or randomly hit an Ace/King if he was bluffing.
The more likely he is to be a Tight-TAG or a Standard-TAG the more likely you should call, because he may play 4bet or fold OOP and may have a tight raising range and not enough QQ/AK/JJ/Bluffs in a 4bet range. A call can also be good if you want to let in some weak players behind, or induce a squeeze you can call/4bet over.
Here I'd 3bet $3 and 5bet all-in. Good luck, Yojimgari
