I am not talking about the money that Hero already put in the pot, which is indeed dead as you said. I am talking about the extra money Hero puts in the pot when he shoves, which is $6.52, not $5.57.
When you add 6.52 to the pot and you loose, you loose 6.52, no?
Like, if villain's raise to 1.50 was all-in, and Hero calls 0.95 and looses, his loss on the call is 0.95, not 0.
