Re: QJ makes four straight vs probable split
 

A normal player can't anticipate this play imo, with top 2 on the river SB thinks he has the best hand 95% of the time.

We have also 2 outs against AQ to save a bet on the river.

What is your line with a spade on the river ? Maybe we can raise fold. AQ can just call. A bluf or a light 'value' 3 bet with this very scary board is very unlikely.

Re: QJ makes four straight vs probable split
 

Raise/fold river when a spade hits would be absolutely awful in this spot. There are not much hands that pay off and dont split with us and to fold if villain 3bets his onecard straight would be disastrous.
