Fairly standard, although I would bet/3-bet or CR this flop more often than check-call.

Either way, I'm stacked just as much as you are.

You would be surprised at how often opponents come over the top when you lead out on a flop with a set, regardless of what they have.

The hand is so disguised, that leading out looks like either a blocking bet, or a weak pair.

Whether or not you agree there, this particular flop is way too draw heavy to let someone have a free card.

the problem i often run into with leading is... that if they raise your lead, then you 3-bet (because flop is draw heavy) it is easy for them to get away from the hand. However, if you check-raise they will often think you could be CRing light and 3-bet you light, etc. Its easier to make a big bet than call one. I actually prefer leading on flops that are not draw heavy because then you can just call when they raise the flop, then go for a check-raise on the turn or lead the turn.
