What makes you fold?

[Tilt]

Are you more likely to fold to persistent aggression, or to large bets?

I find some players are more likely to fold to large bets, but some are much more inclined to call large bets, even with marginal hands. Its like their gambling mentality takes over. But the same players who fold in these situations are much more likely to fold to a string of smaller bets. Its not only that they are just fishing the turn and river. They genuinely don't believe until the third bet that their second pair is no good.

The timing and circumstances of folds are curious to me as well. For instance, I find most players will almost never fold to a checkraise. Another example is a class of players who I find particularly inclined to call to bets on the river if you haven't been betting all along, even sometimes with K high or less. But yet many are more inclined to fold to river bluffs.

I want to understand the psychology of folding better than I do. In many important online situations, persuading a player to fold is largely about addressing their particular psychological/emotional tendencies. What types of players are more likely in the group who folds to large onslaughts? What types need a long "story line" of raising and reraising to be convinced?

After playing with someone awhile, of course, your tendency to hold or fold is shaped by the previous hands you have had with the opponent. But in the early going, when everyone is unknown, it is based on your tendencies I think.

Has anyone written on this subject? Anyone have any thoughts? I know this is somewhat general, but my goal here is to learn to more quickly identify the best way to make any particular player fold their marginal hands. Usually I am playing PLO cash games or NLHE tourneys where this ability is especially important.
