Interesting situation last week: I'm playing an Omaha 8OB / THE mixed game. I'm the SB, post-flop I check, the BB checks and the UTG to the left of the dealer says "call" then puts out 100. There was no bet to this guy, floor is called.
Your ruling:
1: binding bet of 100, because saying "call" indicates intent to bet (plus, perhaps he then put out 100)
2: binding check, because he "called a check"
3: no definitive action, because "calling a check" is undefined, therefore action remains on player to take a legit action
Would your ruling be different if the guy had not put out the 100, i.e. only said "call"?
There was a TDA e-mail discussion on this situation awhile back, and there might be a thread on the forum on it (can't find it)... anyway, I was surprised by the floors ruling, will withhold that so not to prejudice responses.
