Tucking a bust anywhere is not acceptable.
Should a player be penalized for doing this? Say lose you bet x 2 for second infraction?
Now, not expressly forbidden in a tournament, but only say 2 percent of participants know they can still be paid max BJ while tucking and utilize it as good strategy, are those 2 percent cheating, or is it an incumbant on 98 percent of other players to inquire ahead of time for clarification, if it is even a thought to do so having never encountered the "rule" before?
HOw can someone inquire ahead of time if they have never encountered the rule before? Which came first the chicken or the egg?
Again, I say whatever edge you can employ that is not expressly forbidden is OK. After X gabazillion tournaments, one becomes exposed to almost all the possibilities and it becomes the individual players responsibility to inquire ahead of time, to watch for inconsistancies and make those calls, no matter how disruptive to the event or the casino personel.
Besides reading the rules it behooves a player to count their starting stack before play, rather than "trust" the dealer.
Another floating quandry, I mentioned earlier, is the insurance vs even money, particularly in a "sometimes" 2-1 BJ tourney, a 3-2 BJ tourney or GForbid a 6-5 pay tourney. Even though the venerable SWOG views the insurance as a seperate and distinct bet and for practical matters it is, it makes a huge difference in a tourney with those variable BJ payouts.
Rather than get in a Grosjean discussion with the suits in the middle of a tourney, it would be better to find out ahead of time and adjust your play accordingly.
Tournaments at the same casino, let alone different casinos have floating interpertations of all kinds of situations.
TX and the UBT rules folks are the two best at addressing any conceivable "rules" questions. Maybe in the future there will be a "standard" BJT rules. Until then, read the rules, question ahead of time and then be prepared to adjust to the "wronging"
