Live 5/5NL Hand - Comments?

[Murderous]

...BB leads out $75, I check-raised him to a flat $300, he pushes covering my remaining $2500.

I think about it for about 30 seconds and say "nice hand, sir" as I table K6. The rest of the table and additional onlookers are uhhhhing and ahhhhing..."how can you lay that down?", etc, etc...when Villain thoughtfully decides to table A6o. More oooohhhs, and aaahhhhss...blah, blah, blah.

Can you say "permantly burned in mental note on player x"?

Additionally, I like to think that laydown helped my meta-game a bit, allowing me to scoop smaller pots with marginal hands throughout the rest of the afternoon.

Thanks for the replies everyone!
