(1) Reload. No sense in sitting on $1.59, when you could/should be sitting on at least $2, and maybe $5.

(2) Pre-flop is standard/obvious. Why would you be open to criticism? What can we tell you other than to raise more if you assume villains have a wide calling range, and won't differentiate because of the raise size. As a standard though, anywhere from 3-6bb is fine. I'd make it probably 4-5x here just due to stacksizes.

(3) Flop is a no-go. You shouldn't be raising for information. You obviously are *NOT* just going to "fold outright". You do have a call option. So your decision is clearly either to call, or to raise for value. You raise for value "if" you believe villain will continue with enough worse hands to make this profitable. If when you raise, he only continues with Qx, then obviously a raise is terrible. If when you raise villain still continues with hands like 88-JJ, FD, etc, then raising isn't bad. But you should have a plan before you raise, how you intend to react if he 3bets you. You did not have that plan. As a standard, I would probably call this flop. If I raise, it's with the intention of getting the money in.
