What to do here?

[RapidEvolution]

I'm really getting tired of situations like this, but I feel like if I always fold to a 3-flush on the board, it's a waste.

$1,000 Guarantee SnG

Blinds are 200/400, antes 50
Hero is UTG+1 ($10,705)

UTG ($7,690) calls
Hero calls [As, Jc]
MP1 ($10,380) folds
MP2 ($12,385) calls
MP3 ($16,891) calls
CO ($44,765) folds
BUT ($11,250) folds
SB ($9,535) completes
BB ($47,274) Checks

FLOP [Ah, 2s, 3h] (Pot=$2850)

SB checks
BB checks
UTG checks
Hero bets $2000
MP1 calls
MP2 calls
Others fold

TURN [Jh] (pot=$8,850)

Hero? (results in white)
<font color="white">

Hero pushes all in ($8,255)
MP1 pushes all in ($9,935)
MP2 folds

MP1 shows [10h, 7h]
MP1 wins pot ($25,360)

I feel like this is either a shove or a c/fold. With one other person in here, I think it's an easy push...but with 2, I'm uncertain.


I'll also mention that this is a massive freeroll (5000 entrants) with cash payout to top 100 and 370 people are left. (If this matters) I'm waiting on a deposit to clear on stars and plan on doing the $1.00 SnG's to build bankroll up from $50. Can anyone tell what the level of play is like compared to freerolls? (I feel like such a noob asking about this lol) As always thanks for reading and any advice you can offer!!
