I've been experimenting with this when I have no read. Is it worth it to check the turn for pot control from a set but risking a suck out? How about on a rainbow flop?

Situation looks like:

50nl on Party Poker.

Hero ($50.80)
CO ($25.25)
Button ($9.95)
SB ($50)
BB ($43.82)
UTG ($53.72)
UTG+1 ($20.45)
MP1 ($50.75)

Preflop: Hero is MP2 with A, A. CO posts a blind of $0.75. SB posts a blind of $0.25.
UTG calls $.5, UTG+1 calls $.5, 1 fold, Hero raises to $3, 4 folds, UTG calls $2.5, UTG+1 calls $2.50.

Flop: ($10.50) K, 2, J (3 players)
UTG bets $5.19, UTG+1 folds, Hero raises to $16, UTG calls $10.81.

Turn: ($42, hero has $31 left) 3 (2 players)
UTG checks, Hero checks.

River: ($42) 3 (2 players)
...Here bets the river if villain checks or calls a small/medium bet).

Final Pot: $42
