Since you pushed the last hand, I would probably make a comment to the PB such as, "wow that was gettin a little scary for a second before I pushed", or, " that was a little bit too close for comfort, Im gonna tone it down a little bit". The OP said he was chatting with the PB before, so I don't think this would look too out of place depending on the way the OP looked and acted up until this point. However, I think playin the same color could have benefits, so I would probably just toss out 1 black chip, or maybe 1 each on two spots, and keep it out there until I lost them.
