ALL IN for less than SB and BB

[edredpeanut]

A situation came up last night that we couldn't figure out... Here's the set up.. . SB = 50, BB = 100..
Preflop a player goes all in for "25".. All other non blind players fold... SB Folds... BB Checks... So we have a SB of 50 sitting on table.. BB of 100 sitting on table.. does 25 of the SB and 25 of the BB go into the pot and the BB gets the excess?? or.. does all the the small blind and all of the big blind and the "all" in go into the pot?? Thanks

Two pots main pot and side pot
Other is all-in for $25
$50 SB folds $25 goes into main pot and $25 into the side pot
$100 BB checks $25 goes into main pot $75 into side pot.
Main pot is $75, either Other or BB can win.
Side pot $100 only BB can win as SB folded and did not complete.
