The only reasons I thought about folding were the following.

1) Either could have the J of spades, giving me only 6 outs and probably insufficient odds considering that it's probably going to be capped.
2) With their actions there's a good chance that there's 2-3 spades out there already and it will probably be capped.

That being said though, I didn't fold because I didn't know that it was going to be capped for sure, I thought the chance of this guy trying to pull funny stuff was high (given the last hand), and (even though a small consideration) I had a pair that improved to Aces up easily.

I took the chance of making a small mistake in order to not make a big one even though it was almost certainly a small mistake.
