explain to me the mathematics of a blocking bet

[Takin'mChips]

in a flush draw on the flop you should usually bet for value anyway, no?

NL game, you have JcTc in BB. Fold to button who raises 3BB. SB folds, you call. Flop is Ac 5c 6h.

If you check here, button will surely bet and it might be pot size. We are interested in this hand however. Villain could very likely have a hand like A4 or 88.

So how would it look if you lead out with a 1/3 pot bet here? How likely is a raise?

So can you get to the turn cheaper by doing this in the long run?

iirc Bill has briefly alluded to pre-river preemptive betting in the past, and like river preemption he talked about doing it w/ marginal and strong hands alike. He didn't mention draws, but I would think some would need to be included to prevent exploitation on subsequent streets where draws come in.

They didn't get into this in the book however, so I dunno. Jerr, comments?

fwiw, Gus seems to employ this type of play quite a bit.
