How do you like UCSD?

What are somethings besides playing tight and in position that a player can do to avoid marginal situations?(sorry this question is kinda broad, maybe you could just talk about marginal situations)

Remember that when situations are close (between calling and folding) your action doesn't really matter that much.

The most marginal situation I can think of right now are checking flops in reraised pots when you flopped top pair good kicker. For instance when button raises and you 3bet ATs in the BB and flop comes AQ4 you check call a bet, and on the turn you check call another bet.

There's certainly places for plays like these but make sure you're not inducing bluffs that you're gonna have trouble calling later.
