2 pair on flushed board

[Nimradel]

I'll admit I'm a bit vague on how to handle side pots for value, so in addition to comments on the hand, any general advice for these situations would be much appreciated.

At this table, I had been generally aggressive and had been getting a lot of folds preflop and to c-bets.

Villain 1. the short stack, was fairly LAGgy but had gone quiet after a couple of beats.
Villain 2 (sugarbear) was tight-weak, hence my flat call preflop.

Villain 2 has only 840 left in his stack. Check or bet the turn here?

Given the stack sizes I push this turn. I think a lead-out push does three things after your flop check.

1. It may look like a steal attempt in which case you get called by any A (hopefully not AT, AQ) and it may be perceived as a one card flush draw (K, Q, Jd) in which case a low(er) pocket pair might call.

2. Discourages villain, if he's holding a hi diamond from getting a free card that beats you if you check and he checks behind.

3. In SNGs with one player all-in it is not a good idea to bluff at a 0 side pot, because everyone wants the all-in guy to lose, and therefore, this tells Villain "I have a hand."

I don't like preflop, sugar has over half his stack in you are committed to 2K if you connect at all with the flop.

Push turn, I'd be surprised if he folded.
