boolean said:Not true. Power Attack and Combat Expertise apply a penalty to attack rolls, they don't actually reduce your base attack.
What he means is that since Power Attack is limited to your BAB, and your second grapple check is made using a lower base attack bonus (rather than using your full base attack bonus but applying a penalty to the total check), someone might make a case that for that second grapple check, your Power Attack is limited to the lower BAB figure you are required to use for that check.
Edit - as he stated himself between the time I opened the thread, and got around to replying to it
