Suppose the pot is $3. Villain bets 2/3's pot, or $2, so it's $2 for Hero to call. 3 + 2 + 2 = $7 in the pot. So Hero is contributing 2/7's of the final pot, and therefore needs to win (at least) 2 of 7 showdowns to break even. That's just less than 30%.
Notice that our call = Villain's bet, so the fraction is:
bet / ( bet + bet + pot)
I use the fractional part of the bet, and use it to make a quick estimate.
Here are some common examples:
- If Villain makes a 3/4 pot-sized bet, the fraction is 3 / ( 3 + 3 + 4 ) = 3/10
- If Villain makes a 3/5 pot-sized bet, the fraction is 3 / ( 3 + 3 + 5 ) = 3/11
- If Villain makes a 1/2 pot-sized bet, the fraction is 1 / ( 1 + 1 + 2 ) = 1/4
- If Villain makes a full pot-sized bet, the fraction is 1 / ( 1 + 1 +1 ) = 1/3
The implication is that calls on the river are "looser" than most new players realize and it's why stations don't go broke immediately. Still, good players are very careful with their reads before making the river call, or (when betting) before making a "thin value" bet.
