crazy pineapple: TPTK or nut flush draw?

[rsigley]

Anyone have any opinions about this situation? I don't know the exactly one, but I'll just make up a similar one

You hold: A clubs, K diamonds, 10 diamonds
Flop comes: A diamond, 7 diamond, 4 heart

I assume you'll keep the King regardless, but I'm not sure if I should be discarding the A or the 10

I'm thinking if it's heads up I'd want to keep the ace, but if it was 2 or more opponents I'd want to chase the nut flush (or maybe even fold) since it's more likely someone hit 2 pair or better on that flop

I guess betting is really irrelevant since pineapple tables only seem to fill up at micro limits where people bet/call anything
