Game is playing pretty big with numerous multiway pots and a mix of competent/tight pros and splashy recs. All players have over $1K on the table so no short stacks.

I'm 3rd blind($10) and early position player opens to $50, 4 other callers before it gets back to me(both $5 blinds folded) and I call with 8910A

Pot is $310 and flop is J67 with 67 of spades. I lead out $100 into the field. Should I be check/raising here to any bet or would you lead out?

Independent of how aggressive/passive the other players are in the game I like leading out. You get to build a pot with the nut draw hand and have players with inferior draws chase and can even get value hands like J7 in to be behind you.

I know others are gonna say really shouldn't be leading any pot first to act with 4 people behind because that range is absurdly tight so you should get folds; but in these types of loose action games I don't think it's wrong to bet most of the time when your equity is pretty good

Dislike the lead, would prefer a c/r 1k deep

Totally reasonable to lead here, but the small sizing does not make sense.

In a softer live game i tend to prefer check, as opponents will cbet and stack off too light - even when flop checks through and we improve on turn we will often get action.

Everyone folded which was surprising the way this game has been playing. I showed my neighbor my hand when folding and he pretty much said you shouldn't be betting that flop with that hand. There were a lot of hands I thought I would get action from but obviously no one had anything. Check was probably better play in hindsight although seems to be up for debate based on the above posts.

Like monikrazy said, the lead is alright, the sizing is weird for this board texture multiway.

Don't take advice from live players.

Lead is fine, if they all folded they weren't betting nor would make many strong hands on the turn, but as stated size it like you would a made hand so at least 250. Would guess I'm mixing equal c/rs with my leads though

You could lead $20 to get callers. lol.

A big part of PLO is to get your opponent to fold their equities. So if everyone folded here, I know it's a bit sad but it's not a bad result, you're probably only 60% against the table.

Also, have you lead any other hand? What is in your lead range? And do you lead with different sizings?

Leading out is 100% correct imho.
Look at it this way: If someone is raising (playing set, or 2 pair with smaller flush draw, or weaker straight draw, whatever ... you are not folding, but going allin.
If nobody has anything, they'd probably all check, since the board is very draw heavy.
Now let's say turn is a Queen of hearts (with someone playing AK10 with hearts), he goes from having nothing to having a monster, why would you give him a free card?
Or another guy, playing 71010Q, having nothing, all check, turn 7 ...

Key point: You are oop, so it's always more difficult to get paid in that spot with a good hand, but especially oop giving free cards to people, or not putting money in the pot (building it) when u have a monster is def wrong.

Def leading here. Sizing is the question. I would go $150 unless you think a smaller bet might induce. I have led in similar spots vs extremely aggro opponents for a quarter and there is a pot bet and call before it gets back to me. If they are passive, I would go larger... maybe $225 which would set up a PSB on the turn vs 1 player.

I think either option is obviously good, but often table dependent. If it's a loose passive table, then I like leading, as you definitely don't want this flop to check around, and you keep all weaker draws in.

If it's a spashly table, a check may get your more dead money, but I guess it depends on the table's propensity to stack off light on wet boards.

Your donking range is incredibly strong. Pot
