1/3 Wynn LV

Most stacks in this game are 200bb+ which makes for a great game. However, in this hand we end up only playing about $50 effective.

H (LJ) opens $15 (my standard open) 78dd
BTN with only about $50 thinks and finally just calls.
BB also calls who has been giving me action and winning so far.
BB profile is significant. He seems straightforward and will just bomb it when he likes his hand but I have not been playing long enough with him to know if he ever bluffs or overvalues hands.

Flop 566r
BB leads 10
H calls
BTN shoves last 35 ish
Call call

Turn 7 BB checks
H thinks about betting and ends up checking back.

River Q (no flush possible)
BB snap bets 50

SEVERAL THINGS:

1) Should I be opening a hand like 78dd with the short stack behind me? I thought if I got past him, I was fine to take this hand, but it would maybe be better if I opened smaller or over limped to keep SPR small? I know I'm definitely not raising this if there are several short stacks to my left as either one of them will jam pre or flop.

2) What does BB's tiny donk mean here? And further what does it mean when he calls the 35 more with me behind? Does he have 5x? 6x? middling pair? The same hand?

3) Finally, how does this guy show up with a Q here? I know I should have probably bet the turn, but I still have to beat the btn. BB should not be bluffing into a dry side pot, but he may not know that.

I think he's repping slow plays like 55, 56, 89, 77, 34 etc. His tiny donk is weird and he didn't raise when btn reopened it for him. Since it's a bet into a dry side (and you'll often get to see it) I find a tight fold

You need to reduce the number of speculative hands with short stacks behind you. How much depends on the situation. If you have a tilted short stack looking to shove anything plausible then drop them entirely. If you have one that is really tight or is flat calling then just reduce the number a bit and hope other people get into the hand.

BB's weak donk usually means a weak made hand or a draw but it sometimes means a monster hand trying to get a little more money into the pot. The second becomes more likely when he doesn't fold to the shove.

On the river villain shouldn't have any queens but nobody should here, it's really a brick given the action. I would usually just fold the river. It's unlikely your pair beats both villains given the action.

1) I think you have to tighten way up with middle suited connectors and rappers with the short stack behind you.

2) I think it's possible for BB to have literally anything in the spot. You see so much weirdness with a short-stack and no side pot.

3) I think BB can have almost any pair here. I'm calling for $50 as played.
