Am I right in thinking that you have more equity against a wider range than tighter?

I have been playing around with Equilab these past few days and practicing my equity knowledge using the trainer. One thing I have noticed when plugging in different hands as well, is that in general I tend to find you have more equity when against a preflop range of lets say 60% than you would have against a player with a range of 15%.

So let's say you have Td9c
Flop comes: TsKdAc

Against a 15% preflop range we have just 20% equity, against a 40% range we have 36% equity and against a range of 50% we have 45% equity.

I believe this is correct in pretty much all postflop matchups. Am I understanding this correctly?

Yes of course this is correct, else Equilab wouldn't say it. You can trust these programmes they work perfectly fine.

The reason behind this is:
If somebody is playing 50%, equilab assumes that they play the right hands and therefore play the top 50% of hands, so everytime they will add another hand to there playing range, it will be a worse hand than all the hands already selected and better than the hands he didn't select yet. If you put more worse hands in the equity calculations, you of course are going to have more chances of winning. The other way around is true as well. If u are putting fewer hands you will get fewer equity since you are getting out the worst hands of his range.

Please note that you shouldn't just enter a random percentage on his opening, always think rationally about the cards he might have when he played in a certain way. Use all the information you have and then put in a range. For example somebody 3 Bets -> well you of course aren't going to 3BET with a lot of hands, so you can definitely take out a lot of bad hands from his range and if the villain is tight you might even only give him AKs, QQ+

As senormath said, yes. You are right.

When playing vs. players who open wider, you also need to try to see if there is any reason for them to be doing this. Some players will widen their range when being first in as position moves toward BTN. Blinds will 3 bet wider when late positions open. But, some players open wide, 3bet wide, just cause "it is fun to bet". You should always try to keep the reasons behind a perceived range (in villains mind, his reason) in your mind.

I hope I said that right.....

Yeh you both covered it well. Thanks.

I think this helps to calculate equity better in my opinion, knowing that your range only gets stronger against a wider range.
