I know this (bolded) part is not true.
If I declare "raise" (say of a $50 bet) then put 125 in the pot, I can't go back to my stack for more chips, even though I haven't announced an amount.
The ONLY way I can go back to my stack for more chips is if I said "raise make it 200" , then after bringing out 125 in chips I could get more, since my raise was announced in an amount
Oh yea, the "I see your...and raise you..." is common amoung unknowning players, I personally prefer "I call 250 and raise 50 more" Either that or the 5 minute discussion afterwards on why they can not (or more important wouldn't want to) raise a 250 bet by 50 (but the blinds are 25/50 isnt 50 the min bet???) So the strng bt gets overlooked to compensate for their scary raise
