throw it in there and then do the math.
you can enter dead cards to make it more precise.
lets give villain hidden pair of 9's so that all lows are live.
then you have ~20% equity, if there are 2$ in the pot and a 1$ bet you have to call,
you lose money doing that. 3$ in the pot and 1$ to call, you break-even and so on.
in a high-game, you'd lose 4 times 1$ and win 4$ the 5th time.
here you brick ~62.5% and split 37.5% time.
2348J vs 99KKK has ~31% equity, but if you are not on 6th street, you have to look at the playability of your hand, the earlier the street, the more important is the playabilty and the less important are the effective odds.
he knows you go low and when he cant be beaten for the high, you obv have bad playability.
please correct me, if im wrong with my math-part, quite some time ago, that i did that.
