200-400 Hand.

[Catt]

FWIW, about a year ago there was a similar thread (but in small stakes) regarding a flop call against mucho pre-flop action in a big pot, closing the action, with BDs and some possible overcard outs. I (and others) worked through the math in a fairly detailed manner. That hand is different from this in some ways, but the similarities are close enough that any interested in the math might check out that thread. Thread below:
