Because it allows me to raise the turn with something other than a combo draw in these situations...so the regs wont insta push with QQ or whatever and be happy about it.

I don't see what he could have except for A-Q of or 10-10 - I know everyone says that 10-10 would 3-bet the turn, but your line looks a lot like A-K so I wouldn't be too amazed to see it.

I probably vomit and fold but people with much larger balls than myself have been known to make a crying call here.
