when to screwplay?

[runway model]

against an unknown on a dry board, does it make more sense to screwplay on a turn scarecard or a turn blank? for instance -

the CO raises and we 3 bet from small blind with AKo. folded back to the CO who calls.

Flop is A83r we bet he calls
Turn is 6 of the 4th suit -- screwplay?

or same preflop, now
Flop is 963r we bet he calls
Turn is A of the 4th suit -- screwplay?

or against an unknown, do you guys just keep betting until you can get a read?

screwplaying sucks when u have represented a big hand pf

I would just bet in both of those hands. We don't have enough of a reason to believe that villain will bet when checked to, and then calldown with a worse hand.

Here's a recent screwplay that made my day. Villain was 81/33 over 36 hands, and in a few HU hands we played, he bet when checked to with a worse hand. The turn just set-off the screwplay alarm, and blaow!

Moss that hand is hot. I never know when to correctly do this. I think there are quite a few times when I pound away where I could definitely get in a screw play.

Basically, I do it when I get HU with that annoying guy who keeps calling my c-bets, and then betting when checked to on the turn... especially if I had to fold more than once. Against players who are just super aggro in general, going for a bet-3bet is usually better.

First example: Bad time to screwplay, since CO will often be taking a showdown line with an underpair or planning to raise you anyway with an ace. In both cases, a screwplay attempt loses bets.

Second example: Bad time to screwplay, since CO is either hopelessly weak or just hit his ace. Again, I think a bet-3bet attempt is better.
