Raising and multiple All-Ins

Question

After reading the following links about raising after an all-in in NLHE, there was still a scenario I wasn't sure about when multiple all-ins occur.

THE MOST-MISUNDERSTOOD POKER RULE – NLHE “INCOMPLETE RAISE ALL-IN”

In the scenario:

Mike    blind   10
Luke    blind   20
John    AllIn   35      Called 20 + 15 extra
Pete    ...
Bill

Pete's legal raise here would be 55: call(20) + raise amount(20) + extra(15)

If Pete though only had 45 chips and pushed all-in

Mike    blind   10
Luke    blind   20
John    AllIn   35      Called 20 + 15 extra
Pete    AllIn   45
Bill    ...

If Bill wanted to raise, what would the next legal raise be?

Was Pete's 'AllIn' considered a raise because it is now more than the previous complete raise/bet(20) plus the legal raise amount(20)? If so, the new raise amount would be 25 and the next raise would need to be at least 70.

Alternative, is it NOT considered a raise because it was less than the min raise amount (only 10) above the previous all-in. Therefore, min raise amount remains 20, and the next raise would need to be at least 65.

Or, am I missing something and the answer is something else?

Answer 1

Common rules: The initial bet was the $20 big blind. John's $35 all-in does not constitute a raise, and so does not affect the action. Pete's $45 all-in is the first raise. The next raise would have to be $70.

There are a few places I've been with a house rule that an all-in of more than half the proper amount does constitute a raise, and so in one of those places the $35 would be the first raise, the the $45 would not be, making the next legal raise $55 ($35 + minimum $20). This is NOT the standard rule, and such places should be encouraged to change.
