Online $1K buy-in, it's a tournament with multiple day 1s and the top 10% of players advance to day 2. We are 5 handed and 4 players will progress.

Villain 1, he has been opening wide, I have the player marked as "unsure" Might be good, might be bad. We don't have enough info to figure out what their skill level is.
Villain 2, a tournament pro. I have them marked as a good player.

Stacks
Villain 1 52BB
Villain 2 54BB
Hero 53BB

Preflop: Hero has 6 3
1 fold, Villain 1 raises to 2BB in CO, 1 fold, Villain 2 calls in the sb, hero calls

Flop: T 6 3
Check, Hero checks, Villain 1 bets 2.5BB, Villain 2 calls, Hero raises to 7.5BB, Villain 1 folds, Villain 2 raises to 14BB, hero?

Is there anything else to do on this flop in this spot except just shove it? I doubt Villain 2 has T6 in his range. I would think TT would 3 bet preflop, I block 666 and 333.

I realize preflop is a bit loose, but how loose are you calling this spot given that you know Villain 1 is opening 60% of his hands when it is folded to him? I might be against a combo draw, but There are so few turns that we can really feel confident with. We can check back on any diamond, but a 9, a 7, an 8, 2, is going to probably put us in c/f mode.

Comments please.

Ugh, nasty spot. Not sure you can rule out TT from V2 on stone bubble here, (or even T6s from SB, but that's less likely). As you suggested call pf is loose, but you are deep enough and the price was right. Your choices are shove or fold. Don't think call is a good idea, your handis worse against V2's range on any turn and rive accept 6s and 3s. I think I fold here on stone bubble as we still have over 40 bbs to play with and will not be desparate on day 2.

What are the other 2 stacks?

So I don't see folding here ever - I would expect the villain to raise sets OTF, he could have nut diamonds, AT maybe,T6/T3 not in his range. There's a lot of money in the pot at this point - I'm shipping it here. Another option is donking this flop, although I'd probably prefer to donk a rainbow board.

In general when I flop two pair I usually don't raise when its bottom two and I'm HU and in position. The other time I don't raise on the flop is when my opponent has 3 bet pre-flop and is likely to have an overpair, so the pairing on the turn of the card on the board I don't have, would likely mean I would be behind. Then I raise/jam on the turn if the board doesn't pair unfavorably. There have been at least 3 times where the board has paired on the turn and I minimized the loss.

The problem in this situation is that the vast majority of turn cards will kill the action. If V2 has a hand like AT here and a diamond or a 7, 6, 3 or 2 comes he might not continue. The other problem is if a 7, 8, or 9 comes V2 can hit a straight (with a flush draw) or if a diamond comes V2 could jam and it will be hard to call a jam on the turn. The extra irony is that the only safe cards are J, Q, K, or A and they aren't really safe either because V2 can hit a 2nd pair with any of them. And if V2 doesn't hit a 2nd pair V2 could be afraid that we did.

So in this case I would jam on the flop. If V2 has T6s/66/33/TT then so be it. But it is highly unlikely V2 has any of those hands.

The one thing I would say here though is I think the flop c/r is too small. I would make it about 12.5 bb's. We are out of position and there was a caller.

Also, I don't hate the pre-flop call with 63o. While I don't typically call with offsuit cards like this vs 2+ players I happen to like 63 a lot because if we are up against A3 and 245 comes...

Im folding pre on the money bubble multiway. We are only getting ~5.5:1 and I dont think we are realizing 15%. We only have 20% raw equity vs a 60% opening range and a tight condensed sb flatting range.

As played its a pretty gross spot. I cant see the sb having two pair here or playing TP this way (TP diamonds isnt possible), so I think his range is sets and combo draws which means you are either slightly ahead or basically drawing dead. Is a fold really out of the question here? And if we continue I would rather flat and see if we can fade a diamond before committing.

The shortest stack is 38BB. Everyone is pretty close in terms of stack sizes

pre is OK without any bubble considerations but here you're gonna be folding pairs a ton and not realizing enough equity so fold pre

You should rethink that 60% assumption. That would be like 99.999999999999999th percentile aggro and significantly wider than people open BTN let alone cutoff.

I think I fold pre in any case once SB calls.

fold pre.
If call pre flat call flop due to bubble. If raised, call a reasonable sized raise and re-evaluate turn.
Ask yourself when you want to raise, are you bluffing to take it down or you have a good enough hand to play for stacks?

It is money bubble you are supposed to be super tight against even or larger stacks.

It's a fold pre, as played has to go in , the value we get from defending this pre is here right ?

Yea I think it’s a fold once sb calls. I think I would even fold pre if it was just bb closing action with no sb call. Idk 36o is pretty bad. I’m fine with 35 as a call but not 36o. It’s hard to realize equity in a 3 way pot oop.

Suited 36 can call but no 36o. I think I would just call flop raise and cry call turn shove. Looks really bad though based on action. I don’t think A-10 or K-10 is putting that raise in. Idk maybe you run into stupid over pairs spazzing here sometimes? Idk. Very annoying spot. Flush draws can go wacky also like AK or AQ dd.
