So basically V1 senses weakness, raises his pair, folds everyone else and wins the main pot vs the allin shortstack. Quite possibly whichever pocket pair below QQ raises first folds out all the others. 99 can be facing 5 lower pairs and 5 higher pairs, of the higher pairs 2 can fold to a raise. The lower pairs all have some possibility of raising and bluffing out or 99 so we should just put in the raise ourselves.

Maybe results oriented thinking but I'm back to my original plan thinking that this is raise/fold or just a fold on the flop, calling makes your hand unplayable and effectively burns money most times you do it.

if someone comes over the top after you raise, are you getting your stack in?

Raise/fold but I admit I haven't done any maths on how much equity 99 has against a deeper stack's flop 3betting range.

Hero raised flop, and both V's call from position. I honestly can't see either calling with QQ or JJ in this situation (especially the V in the CO, he's really flatting with a player behind holding JJ+? Nope...), and 100% ruling out AA and KK. Both are standard 3bets. That leaves TT as the only legit pp holding that beats hero's 99. Calling the short stack shove could easily be seen from either V as "I put you on AK" and raising to push you out.

Like I posted earlier, before the results were shown, calling allows V's here to play perfectly, and puts you in a rough spot, one you can easily make a mistake.

Had to raise or fold. Call only to induce a raise that you plan on also calling.

Yep, this. Since we raised preflop from early position, villains aren't giving us credit for A3 or 22. When you call here, villains with smaller pocket pairs and broadway flush draws are going to think they have fold equity.

I like a raise/fold here, to $225. Raising in this spot signals that I'm ready to gii with my premium pocket pair here. I expect 1010 and JJ to tank hard and usually fold. Same with non-nut flush draws Q10/J10/QJ, all of which have strong equity.

If we're calling in this spot, it should be to induce a bluff-raise that we'll call. With QQ/KK I'd consider that line, but there are just too many semi-bluff hands with 12-15 outs against pocket 9s here. Since I don't particularly want to play for stacks with this medium pair (might be profitable, but HUGE variance), I think raise>fold>call in this spot.

Bonus: the times when we raise and force out 1010/JJ are going to be great for our image and will sometimes tilt the players who folded the winner.
