Common sense fail...




Once you call the pot will be twice as big, therefore you only need half the equity you think you need.

You're treating it like you go all in, risking all your money, and he doesn't have to risk anything, but can still win your whole stack if he wins the hand. You would need 94 percent equity there (less than 100 because of money you previously invested + dead money) , but you only need like half that equity if in addition to this 2 you put down, villian also risks 2.

Just use your common sense mate! If you are obviously way ahead call!
