I'd echo comments on "why play solid players extremely short during a time when you're doubting you decision-making?"

I'll depart from others though and say I don't like Hand 2 much. I think you need to either 3-bet the flop and lead, or call the flop and lead hoping to bet-3bet. Granted the chances of it checking through on the turn HU are probably pretty small (depending on player), but I don't think it is a chance you should take on the action and flop and I'd press your perceived advantage early in the hand.
