Flop : (8.36 BB, 3 players) Tc Qd 3h
BB bets 4 BB, Hero?

Open smaller pre, off 17bb going 2.4x is too large, I'm making it 2.1x. I'm calling flop and folding turns where we don't turn equity/a jack.

Donkbet vs 2 players could inform that he have a hand, maybe top or 2 pairs, maybe only oesd, but I think You should fold this. You have one more player more here and they both have a lot of connectors and one gappers (with Q).
Also as trent said. 2,1 bb is better open than 2,4.

Did he playing before like that? I thinking about this donkbet

And I also think about all in preflop... maybe it will be better line

You have an M<10 (7.95), shove preflop here.

didn't understand
what's M<10?

In no-limit or pot-limit poker, a player's M-ratio (also called "M number", "M factor"[1] or just "M") is a measure of the health of a player's chip stack as a function of the cost to play each round. See https://en.wikipedia.org/wiki/M-ratio

From Harrington On Holdem books, M<10 you should be open-shoving to best use your fold equity (and other reasons).

Thanks very helpful. Will take a look

Shoving preflop here with JJ would not be the most profitable play here in a $4 MTT. By open shipping 17bb, we fold out a lot of worse hands that would otherwise rejam on us and our shoving range can't be unexploitable unless we are also open jamming AA and J9s here too.

Open shoving JJ here from a GTO/unexploitable standpoint would be correct if we are doing so with our entire range, however, in a $4.40 MTT, using exploitive strategies is going to net us more EV. Our opponent's are going to be playing close to perfect when we open jam, by having a standard open range, and even a limping range, off this stack, we allow our opponents to make more mistakes and we can get postflop, although we can end up making mistakes ourselves.

If this is a very hard, mid/high stakes tourneys, we can advocate open jamming our entire range here because we do not have an edge on the field/table and will make more mistakes than our opponent's by having a raise non-allin or limping range here. In a $4 MTT where we likely have an edge on the field/table, we can start adding in a limping/raise non-allin range in these spots to maximize our EV knowing we will make less mistakes than our opponents.
