There's a disparity between betting and calling that's confusing me. If the bettor bets 50 into 100, there's something that equals 1\3, but then the caller is calling 50 to win 200, which is 1\4. Does this mean you need a stronger hand to bet than to call a bet?

yes

even before the math gets involved, it's always been standard that you need to be a lot stronger to call than to raise

I just realized I am confusing break even folding percentages, as the bettor, to pot odds, as the caller..
Thanks for the reply.

Right. I drafted the following before seeing the above, but I'll post it anyway.

I have a problem with your math. The bettor needs equity of 1/4 assuming villain calls, for with a win he will collect a total of 200 with an investment of 50; i.e. his “fair share” of the total pot is 25%. Similarly, the caller’s fair share is 25% for he also will invest 50 to collect a total pot 200 if he wins.

This simple example implies that for a bet/call situation, needed (break-even) showdown equity is the same for both bettor and caller. However other factors such as position, stack sizes and realized equity come into play. Naturally if the bet/call doesn’t close the action, then this result is only a first-cut look at the situation.

that's the gap concept, but I'm not sure it really applies to post flop decisions since especially with smaller bet sizing we can call at a very high frequency because we are getting such good pot odds.

although conversely you can bluff bet but you can't really bluff call. unless you are floating.

Whenever you are the aggressor you always gain a certain percentage of fold equity across a range of V in similar spots. So if you are in an EV=0 spot based on equity and pot odds, then you should tilt long term results in your favor by gaining a few folds instead of going to Showdown/chopping.

I've seen (bad?) Players fold to $10 bets into $400 pots when a bad card comes out.

You see this all the time in tournaments, a Player can shove a weaker range than a Player should be calling with. This carries over to cash as well, so after you range an opponent you need to apply your holding against that range .. which forces your holding to be stronger than 'x' percent of V range in order to call.
