Now if, again, you chose C.....the prize is in B...the host KNOWS IT...he will open C...you switch to B...you will HAVE IT....
so the only chances to get it by sticking with you first choice (C) is if it's really in C....if it is in eighter A or B, you will NOT have it if you stay with C...but you will HAVE IT if you SWITCH....

I understand where you are getting at and a certain 50% change is always better than a 33% chance thus you should change
but your original 33% changed into 50% wether you change or not
you are saying if you choose now again you will have a 50% chance of getting it right , this means that I stay with my choice and dont change I still have 50% chance , thats why I am saying it doesnt matter if you change or not
