Thanks for all of the replies.
Sorry I wasn’t more explicit in the OP - - -
At no point during either scenario was Player A all-in.
Player C never touched Player A’s chips, just eyeballed it and announced what he saw (he was accurate, if it matters).
It’s not a deepstack tourney, and we only have 4 colors of chips in play at the beginning,
so not too hard to quickly count what you see.
This is a home game mtt, 25 – 30 players, mostly regulars but a few newbies.
Overall competent skill range, but some are pretty new to poker overall.
The majority play occasionally, and some regularly, at B&M casinos.
A handful have never been inside a poker room.
It’s self-dealt, so there is a remote possibility that at some point Player A, who is a nice enough guy but not very talkative
while in a hand, could also be the dealer. I figure we’ll cross that bridge if/when we ever get there.
In which case, Player C may actually be a benefit.
The comment I made to Player C after the hand in scenario 2 was kept light, and I am positive
it was not received negatively. But unless a “Player C” consistently does it or does it
to spite the rules/etiquette, I can’t see myself handing out any kind of penalty
for it beyond, “hey, don’t do that. OPTAH.”
