Bart and Dave talked about this hand where G-man had 67s vs. Larry's QQ. The board ran out J43 one spade, turn Js, river As. G-man bet the $350 on the turn into Harry and Larry, semi-bluffing spades with a gutshot - Harry folds, Larry tank-calls. The river As made his flush, Larry checked, G-man thought for a long time and bet $500 (around 35% of pot) and Larry folded his queens.
Bart and Dave were speculating as to whether or not G-man would barrel the river on an off-suit 9, continuing to rep the J. My question is, what if the river was an off-suit A? Should G-man bet that on the river as a bluff?
Thank you, Chris
