management argue

Copy of letter sent to Bob Ciaffone. His response is in blue:

Bob,


No limit game. Blinds are 100/200. UTG bets 800 (a 600 raise). Next player, UTG +1, goes all in for 900 total. If the 3rd player wants to raise, what would be his minimum bet and why?

Second part of this is there any specific rule covering this?
<font color="blue">[Bob Ciaffone] not exactly, but the "last previous bet or raise" is the $600 more from the UTG, so he must raise at least 600. The all-in bet is not considered a raise because it is only a $100 increase </font>

There seems to be a disagreement as to whether the total bet needs to be 1400 or 1500. Everyone agrees that the raise amount is 600. Some say that this gets you 600+600+200 = 1400 (or 800+600). I'm of the opinion that he needs to call the 900 and then can add the 600 raise on top. This makes his minimum bet 1500. If 1400 is correct how you can just ignore the extra 100 in the 900 bet? It needs to be acknowledged should anyone just want to call; meaning that a player cannot just call the 800, but need to call 900.
