[John Deere]

With second pair and backdoor straight and flush draws, you need to be playing this hand. Even if you are behind, you usually have the equivalent of 9 outs to improve (if you value the backdoor draws at 2 outs each) to what will likely be the best hand.

If your opponents are very aggressive and you're worried about them raising you with a worse hand, then you need to consider check-raising. The people that will raise you with bottom pair or overcards are the same ones who will reliably bet on the button whenever they're checked to.

But this opponent could still re-raise with a hand worse than yours, right? Well, that's possible. But think about it... how often do you see someone raise a single bet with a worse hand, compared to how often do you see someone 3-bet a check-raiser with a crap hand? No reads are perfect, but some are certainly more reliable than others.

Re-evaluate on turn depending on if he re-raises and if your hand improves.
