Dear All,

Goodday.

Usually in 100bb the open raise size is 3bb. I wonder how do you adjust for deeper stack let say 300bb?

If open raise AA with 3bb in 300bb are we giving away too much implied odds for opponent?

what about shallower stack like 20-50bb?

the idea to constantly open raise with 3bb is to disguise our hand isn't?

Thanks

1) Your opening raise should be 'enough' to get you to HU or 3-ways on the Flop. Adjust it accordingly if you are getting called in more than 2 places or taking down 'too many' pots PF.
2) Your opening raise could be affected by the actual remaining players left to act .. tight or loose.
3) Your opening raise shouldn't be affected by your hand strength but could be affected by your position.
4) Your opening raise should be adjusted by the number of Limpers already in the pot.

I have 3 opening sizes at 1-2 .. $7, $11 and $16 (yes) and I will somewhat mix them up evenly across my range (which is very wide), position and game flow. The key is to know how to play the various pot sizes depending on your position and amount of opponents. Yes, I do have to c/f 'a lot' when I open from EP, but with my wide range opponents don't know if I'm betting the Ax or the 47 on a A58 Flop from EP either, thus they typically have to have 'something' in order to call.

With shallower stacks I always want an opportunity to isolate PF or Flop. So I usually make sure my raises or Flop bets are less than 50% of the smallest stack or 150% (over-bet) in order to force a side pot to be made before the next card comes out.

You typically want to maximize value in poker. There is something to be said for disguising your hand strength by remaining consistent, but if it's putting you into tough spots post-Flop then it's the wrong size. You need to adjust it to the table dynamic or just plain 'adjust it' so no one can pick off your raise to range formula.

In general don't worry about stack depth until you start to look at sizing your Turn bet if a Flop is to be called. You may .. or may not .. want your opponent to feel obligated to put in their remaining stack as part of your game plan for this particular hand. GL

You open raise size should be dependant on external factors (table style, position, effective stacks, etc) and should not be dependant on hand strength

You open raise size is meant to narrow the field and to indicate that you have a hand in your opening range (depending on the situation, your range may be wide and have a mix of drawing hands, value hands, and bluffs, or it may be narrow with only value hands).

The open raise size should be larger if there is less risk.

For example, cash games have less risk of a bad hand ending your session, so you have to open larger than 3x to get the same amount of affected risk to the player

Conversely, when you have been playing in a tournament for 10 hours and are nearing the bubble, there is a lot of risk, and stack sizes start to drop relative the the blinds, so an open of 2.2x carries more impact than an open of 4x in level one of the same tournament.

There is no static formula, as a lot of it is dictated by the table. if you have a couple of loosey goosey players who won't flinch until the bet is 8x, then that will become the standard raise.
