Played what I thought was a fairly standard spot yesterday. I don't recall exact stack sizes, but you can infer them if you need to.
I defend BB with KQs from UTG (TAG) raise. Flop is 877 with my flush draw. He Cbets 1/2 pot, I check raise 3x; he calls. Turn is a blank, I shove for pot. Results not important.
I looked to see how PIO would play this spot, and saw my hand is a pure call on the flop. We know we need to mix some check raises with FDs, and also we need to have some flushes in our check call line. I wonder why this combo never raises (in theory, anyway).
Which FDs check raise the most?
I think I was able to get a screen shot here. (I used an SPR of 5.6) You can see the pattern of which flush draws check raise. Interestingly, it also never raises its weakest draws.
I am wondering what heuristics I can glean here, besides the obvious, don't go to war with dominated flush draws...
