Lunch game. .25/.25 $25 buy in. I limp in with 3h4h in middle position. Dave raises to 4(-ish?) from the SB. Maybe three others see the flop with me. Comes 25x two diamonds. I have an open ender and it checks all around. Turn is Ad which gives me the nut straight but puts a possible flush out there. Dave leads out for 20, folds to me and I call. Folds around and it's heads up. Rive is a glorious blank. At this point, I'm fairly certain that Dave does not have a flush. In retrospect, him checking the flop with two diamonds should have been the first hint that he did not flop a flush draw. The more that he waits after the river card is revealed, the more I feel like he does not have a flush. My read is that there is no way I'm beat here. Having the nut non-flush hand helps because if I had two pair, I'd have to consider a higher two pair or a set being out against me but with the strength of my hand, I knew I just had to contend with the flush or no-flush dilemma. I am telling myself that I will call whatever bet Dave puts out there. After some more camera time, Dave pushes all in for about 4 stacks. I actually make a reactive quick call. Also in retrospect, pushing all in is a "go away" bet and not a value bet. Dave shows a black Ace and Kd for the nut flush draw and top/top.
So it occurs to me later that I could have raised the turn. I had an inkling that Dave did not have the flush at that point but I certainly can give him credit for a diamond draw. I hadn't noticed him checking his hole cards at any point in the hand though there were many players to the flop and turn. I also hadn't solidified my read of him not having a flush at that point of the hand either.
So to tear this hand apart, let's assume that I had the same certain read that Dave did not have the flush. Is it a valid "right" play to let a blank peel off on the river instead of popping the turn? Previously on the blog we've discussed pushing all-in with a set against a possible flush draw in order to snap off the action even though more money could possibly have been made by pricing out a flush draw and letting a blank fall. Taking the pot down early was an attempt to minimize risk of a redraw at the expense of making the maximum on the hand. If you are fairly sure that your opponent will bet a flush draw aggressively, is it OK, to flat call the turn in the hand described above to keep the pot small and cut down on stack swinginess? I know, you are supposed to get your money when you are ahead and in the long run you will be ahead but if you raise the turn and you open the door for someone to push on the turn as top-top/nut flush draw may very well do. Is that controlling pot size or just good ol' weak/tight?
