Too tricky? -- corrected

[NotAClue]

If the opponent has KK then UTG is giving the button 10 outs not just 2 to beat him. If Button has AA, then button has 6 outs. All of this for free on the turn. Not to mention UTG might make a huge mistake on the river laying a winner down. All in all get the money in when you're pretty sure you're ahead.

Plus if you check the turn after checkraising the flop, people are much more likely to call your flop checkraise knowing that they're likely to get a free card. Not good for your bluffing equity. You want people to know that if they call a flop check-raise they're facing a pot sized bet on the turn.
