From memory, the general consensus of those TDs polled was that you would not disturb the underbets / underraises once substantial action had occurred. But up to that point you would require the bets to be adjusted to full amounts.
Very interesting posts again with so many cases in my 2000 amateurs players tournaments!
Another exemple that happened:
(I tried to remember and rebuilt the elements so that the main problem may be analyzed)
- FLOP
- A open bet pushing one 5000 chip and saying "3000"
- B calls de 3000 in silence
- C push 4000 saying "ok" (intention to call)
- D push 4000 saying "yes" (intention to call)
- E push 4000 saying "with you" (intention to call)
---> The dealer (very tired after an 8 hours day but anyway) gives back the 2000 change to player A and put all the pot in the middle
---> Nobody notice the error (very tired too but anyway)
---> Turn is placed
- A open bet 7000
- B raises 15000
- C folds and throw his cards
---> another player out of the hand and who was counting in his head just says that the previous betting round was wrong
---> everybody agree with the error and the amounts but with different reasons:
---> players A + B + Dealer say it was clearly 3000 (no one realized that the other players did bet 4000)
---> players C + D + E say they eared and thought it was 4000 (no one checked the change back to A and the 3000 from B)
...
---> Floor now must deserve his salary ...
