AK blind battle vs regular

[SunyD]

I'd raise preflop to about $21. Once SB puts in the third raise to $99, you might want to slow down a bit. I doubt he's folding anything at this point, so your re-raise all in is too much like gambling 50/50, if that.

I'd say once SB makes it $99 - just call at that point, and use your positional advantage to outplay on the flop.
