Preflop
I might isolate a single limper with a small pair like 66 in a cash game, where stacks are around 100BB. However against multible limpers and with short stacks like in this situation, the hand play much better as a limp behind. You are not getting them to fold with a small raise, and this mean, you are setmining. And when you are setming, you want a deep SPR. Raising create a shallow SPR, which is bad for your hand.
Postflop
Raise his donk bet to around 1.000 chips and put him all in on the turn. Your massage raise is giving him to good odds to continue, and you dont particularly want to make this a 3 street hand, when the board is wet. It sucks, if he turned a flush, but you still have 10 outs to fill up on the river, so its not the end of the world, and you are still far ahead of his range. Him having a better set is an outlier and not something to worry about. He put chips in very bad on the flop and hit his 2-outer. Good for him, say "nice hand" in the chat and find something to bite.
