BB 40bb 3-bet all in range
I've been studying on pokercoaching.com and just recently gto wizard. Both say to be 3-bet jamming against the button with pocket pairs 88-22. I'm just kind of wondering why? I'm really suppose to be comfortable jamming 33 100% of the time against the buttons open?

Agree that seems strange at 40 BB in an MTT vs an open around 2BBs. Are you sure the settings are for MTT with an ante? IDK, at 40 BB, I usually call here. Will start shoving at around 20 BBs or lower.
I imagine it's because it's difficult to win the pot postflop and you're almost always ahead because it's hard to get dealt a pair. And maybe when you are called you're still flipping a fair amount of the time.
I'm assuming this is chip EV; I certainly wouldn't play it this way at this depth later in a tournament.
I think the opening bet size matters here.
I will typically raise 4x the original raise size OOP (SB or BB) preflop. If my raise sizing is > 30% effective stack then I will jam.
So if the original raise size is 2x I will make it 8x HU. If the effective stack size is <27 bb's I will jam. Regardless of my specific hand.
If the original raise size is 2.5x I will make it 10x so if effective stack size is <=30 bb's I will jam.
If the original raise size is 3x I will make it 12x so if the effective stack size is <=40 bb's I will jam.
My raise size goes up if I am squeezing with one or more callers. I add the original raise size for each caller.
So if the original raise is 2x and there are 2 callers I will make it 12x so if the effective stack size is <=40 bb's I will jam.
I keep my raise sizing the same for all hands so there is no way for anybody to know whether I am strong or bluffing.
If I am not jamming with a small PP I will almost always just call in the BB.
The situation that changes everything is if everyone before me has limped in. I am will jam < 40 bb's than just raise OOP. However the original limper has to be limping prior to this hand or he can have a monster.

That's right, it is hard for V to have a pair there -- probably less than 15% of RFI range. But a good portion of V's calling range will be pairs -- probably more than 30%. So the math seems off to me, because we only take down 3-5 BBs or so when we get the shove through, But when we are called, we are either a very slight favorite to slightly behind over card combos, or 17-19% to win against bigger pairs (depending on suits).
So if the original raise size is 2x I will make it 8x HU. If the effective stack size is <27 bb's I will jam. Regardless of my specific hand.
That sounds like a very expensive mistake, do not do that. For example jamming AA for 27bb BB vs BTN is gonna be like -100bb/100h winrate type of blunder.
Having consistent 3b size with all the hands you 3bet is obviously good. But non-ai 3b ranges and 3b jam ranges are completely different.
And yeah having 40bb jams in chipev is fine:
Pretty marginal but fine.
That seems crazy to me, around 20 BB yes
