Implied odds equation: (odds)*(bet) - (pot) < (ESS)
ESS is
effective stack size, but it's misleading. You
don't necessarily expect all villains to
stack off on you when you
catch your
set. ESS in this equation is really how much you can expect villains to
call.
Odds of flopping a
set when you start w/ a
pocket pair are 7.51:1. (I round it up to 8, but that's my choice to err on the side of caution, you seem to be rounding it to 15, which is extremely conservative in my view)
1st
call: odds = 8:1 = 8/1 = 8 ; bet = 0.16 ; pot = .02 + .04 + .16 = 0.22
8*0.16 - 0.22 ?<? 3.5 ----> 1.06 < 3.5 TRUE
You can make the
call with
implied odds, as long as you can get $1.06 more into the pot before you win (that's $1.06 that does NOT include your bets, i.e. $1.06 from villains).
2nd
call: odds = 8 ; bet = .50 - .16 = .34 ; pot = .02 + .04 + .16 + .16 + .48 + .34 = 1.20
8*0.34 - 1.2 ?<? 3.5 ----> 2.70 < 3.5 TRUE
You can make the
call with
implied odds, as long as you can get $2.70 more into the pot before you win (same caveat).
As you can see here, the amount you need to get into the pot to justify a
pot odds call is not dependent on the number of villains. You
don't need to get that amount from each of them, you just need to get that total.
