With A-K-10 and 3 spades showing by the turn, I would be going slow too. After the river, I would probably fold to a big bet especially as there was little invested in the pot.

I too would have raised pre-flop. In my opinion, if the short stack is going to push they generally tend to do it based on their cards alone and most won't care if you raised or not. If fact they probably prefer a raiser because there is a good chance of geting called. I know when I am short stacked and get a hand to push with, I hope someone will raise before me. And I have seen it too many times when people limp with big pairs and the BB has junk like 8-3 off suit. Then flop comes down 8-3-2 rainbow and then KK looks very nice but it's burn time (yes, this happened to me once, except I was the one holding 8-3. lol).

However, I have seen the top pros limp from early position with premium hole cards hoping to get a raise so they can re-raise. In fact I posted a video clip on here about it and he swiftly folded his A-A on the flop becuase of too many people in the pot.
