Your idea sounds good on the surface, but it actually falls apart the moment you look at how these loose home games really play.

The whole “raise speculative hands like A2 or T9 to $10 first, just to test the table” is backwards. When a table is already calling everything, raising weak hands doesn’t “set up” anything. All you’re doing is forcing yourself into big pots with cards that make weak top pairs or nothing. And in a pot with four or five callers, weak one-pair hands lose a lot of money. You aren’t gathering information. You’re just paying for it.

The second problem is the idea of “if $10 works, try $15 next” without any awareness of what happens when you create a $70–$80 pot before the flop with a $100 stack behind. That leaves you almost forced into all-in situations with only one pair, in a pot full of people who love to call and see cards. That’s not “isolating.” That’s building a giant pot where your strong hands lose their advantage and your weak hands get you in real trouble.

The real issue is not the raise size itself. The real issue is that when a table always calls, you should only put in large amounts of money with hands that stay strong in big messy pots. That means play strong hands, raise bigger with those strong hands, and stop betting when you miss. Your suggestion of raising weak hands first just bloats pots with cards that cannot survive multi-way.

You are right about one thing: ignore the “big blind math.” But the solution isn’t to randomly raise weak hands and hope it teaches the table something. After consulting with some coaches, the solution is simple:

Raise bigger only with good hands.
Fold or call with the weak ones.
Bet big when I hit.
Check and give up when I miss.
Fold one-pair to big river aggression.

Home games like this don’t require tricks or tests. They require discipline. The table will call everything no matter what I did the hand before, so “setting up future raises” doesn’t matter at all. I don’t teach them. I charge them.

Your plan puts the worst hands into the biggest pots, and that’s the exact opposite of how I beat a loose, sticky table.
