39: Multiple Chip Betting
When facing a bet, unless a raise is first declared, multiple same-denomination chips is a call if removing one chip leaves less than the call amount. Example of a call: preflop, blinds are 200-400: A raises to 1200 total (an 800 raise), B puts out two 1000 chips without declaring raise. This is just a call because removing one 1000 chip leaves less than the amount needed to call the 1200 bet. Placing mixed denomination chips in the pot is governed by the 50% standard in Rule 37.
Nick,
1) Your example is the exact example listed for Rule 39 of the current TDA rule set!
2) I state my case for scenario 1 solely based on the TDA rules. As per rule 37, the "short" raise amount of 400 (1500 - 1100 = 400) is more than 50% of the current raise amount of 600, so he should up the bet to 1700. Furthermore, rule 39 does not apply here because the 2 chips(1000 and 500) were not "same denomination"
Nick, agree, however, that if a casino has a house rule that favors a 100 % raise instead of a 50 % raise, then the 1500 old be a call.
3) Btw, there was a previous version of the Multiple Chips rule, maybe circa version 1 of 2009, that did not specify "same-denomination". In that case, the 1500 would have been a call. However, that rule was rewritten in the language that currently exists for Rule 39.
