One of the few things in my notes on opponents that I've been disciplined enough to type in is what they go all in on.

If my notes say: "all in 88 AQs TT 55" I definitely call. Useful data.

If they say "all in AA AA AA" I fold. I've done it maybe half a dozen times.

If I don't have any notes or reads, I would probably always call an all in.
