I have a big issue in my game of knowing what hand percentage of hands to defend after opens and calls

Eg.

UTG+1 open 3x
CO calls
btn folds
Sb folds
Bb? Hands like Q9 off suit, A4 off suit should these hands be like slam dunk calls or are they really boardaline?

And should my range tighten or loosen when there is more calls? I know theoretically I am getting a better price the more callers but hands that play horrendously multi way like A7 off suit etc are they still just calls because of the odds? Any help would be great thanks

You have to consider equity realization, and not just pure equity. We're getting a better price but hands that mostly make one pair hands, and significant money only goes in when we're dominated, and get bluffed off our equity too often need to be folded.

The simple answer is we tighten up with offsuit hands and call with more suited and connected hands, but even that is a little over simplified, since if we go too crazy with junkier suited stuff we start having issues with reverse implied odds

You have a bunch of different questions that could all be solved at once by looking at a preflop sim

Q9o and A4o are slam dunk folds facing 3x without the cold caller. The cold caller makes it even worse as these hands play poorly multiway and BU's range should be relatively strong with a lot of hands that dominate you.

Calling this wide is a pretty huge leak. These hands are extremely borderline even vs. HJ min-raise and no cold caller.

For most hands having to deal with a third player is a bigger negative effect that any improvement to your pot odds, unless the cold caller is a huge fish.

Okay thanks for the advice man really appreciate it!

Okay thanks for the reply first of all man appreciate it!
Im really suprised that a4o would be a borderine defend v a HJ min raise.

I must be way overcalling from the bb if that is the case, what hands are we defending mainly suited cards? Are we pretty much avoiding most unsuited cards besides like 67 78 89 etc

Like anero said, you can find the answer by looking at a preflop chart.

As for whether you want to play tighter or looser with a cold caller, think about the kinds of hands you yourself would cold call--it's probably weighted towards stronger broadway like KQo and AQo. Not so much QTo and Q9o (hopefully). The aggressor can have these hands because he's raising them together with all his strong hands. The cold caller is 3betting most of his strong hands, so he absolutely cannot afford to flat too wide.

This is why as the BB, hands like QJo play fine vs a single open (since we still dominate some part of the aggressor's range). But once someone cold calls, QJo gets dominated way more often.

I do play in a lot of average fields were they are just calling too much, like they can rock up with 10 3 suited in the cutoff after a UTG raise and they flat, not all the time but that sort of stuff goes on, so that’s why I just think those sort of hands are slam dunk calls, but appreciate you guys for correcting this flaw in my game!

I’ve been going through some preflop stuff over last couple of days and enjoying it so thanks for the help!!
