[Bob T.]

-Frequent coldcaller.

-Coldcalls preflop, and folds for one bet on the flop.

Both of these tell me that the player is loose, and probably playing hands that are tactically incorrect.

- Rabid blind defender.

If they defend with any two, then I can assume that they probably don't have anything from the blind until they show some strength.

- Bets/raises/plays draws fast on the turn.

If they do this, one of us is going to get full value when I have a medium strength hand.

- Very tight in the blinds.

Then I open raise whenever they are in the blinds.
