Under bet

[Guillaume Gleize]

Hello
A question about insufficient bet with no verbal announcement

Texas Holdem - 4 players – post flop – Blinds are 5000 10000
Player A (stack 200000) goes all in for his 200000
Player B (satck 100000) silently push only 20000

They call for the floor.
1)   Player B must go all-in too with its 100000?
2)   Player B can choose to fold and forfeit the 20000?

I know player B is facing an open bet so is supposed to call but can't the TD use the "gross misunderstanding" here (if he thinks player B is acting in good faith)?

[Dave Miller]

The decision may be based on whether the 200,000 bet was properly counted or announced.

Then again, this might be a Rule One situation.

Hello Dave,
First TY for the answer.

Yes, the player A did bet correctly but in silence: he pushed everything in the middle.
Some floors around me keep on saying it must be an automatic call because facing an open bet.
But here I used the #1 rule as a gross misunderstanding because of:
a) The huge difference between the amounts!
b) It involved all the chips of B (if B had 400000 or more > I would not have used the #1 rule and would have stay with the call)!
