Here's an easy question: how often do you guys go for the check-raise here, and how often do you just lead into the field?

SB checks, Hero...?

Usually just lead. With 5 people taking that flop someone with AAxx or even a weak 5xxx won't likely bet for you (let alone call a check-raise). Lead and hope to get a call from a weaker 5.

We don't really want to end up giving a very costly free card if someone hits their ace with A5xx or their pocket pair on the turn.

Pot is nice enough just to push and hope it holds if someone calls.

just pot it, lots of people taking this flop, someone is bound to pay you

5 way, aces likely aren't c/betting, so leading is better. If it was 3 way, I'd checkraise.

I am almost always leading this flop.
