A Clarkmeister Play: The Ace High

[Goodnews]

Can you explain why it is a must bet? I don't have any indication that I am ahead of SB, and I am probably ahead of the Button.

Do I fire at it and hope that SB (the rock) doesn't call? Is this a value bet? If I fire at it and the Button calls, I could have possibly given SB the pot odds to call and I would never know if I am ahead or behind. Wasn't it a wiser choice to give the SB a 4:1 call than a 5:1 call?
