Two Strategic Errors

Today I will show you two positions that are pretty easy to analyze from a strategic standpoint.  Both are ones where I chose the wrong strategy OTB even though I knew it was wrong.  After ignoring my opponent's threats my biggest issue is overthinking positions and picking plans I know are wrong.  If anyone has a cure let me know asap. 

The first position requires a prelude.  This is the board after move 8

In the above position black can still entertain ideas of central action.  If he can play f5 white's center may crumble and black will be fine.  But white nipped this idea in the bud with 9.g4

White clamps doen on f5.  It should be pretty obvious that white will also castle queenside.  Black should almost immediately play a6 intending b5-b4.  If white plays a4 then he has weakened his king somewhat and black must agree to play c6.  At any rate black's chances must be on the queenside.  Can you guess the knuckle-headed move I talked myself into?

In the next position white is comfortably up in material, position, and time. 

Blacks rooks are disconnected.  His bishop is trapped behind his own pawns.  Black's one plus is the queen which can generate some counterplay on e2 or e4.  But the queen by itself can't really do anything.  White has plenty of time, the goal should be to keep the bishop behind it's pawns, organize his own ranks and then perhaps grab the a-pawn or wait to exploit black's weaknesses.

It's terribly embarrasing to post what I played but otherwise I will never learn

The moral for me is to just assess the position and play the position not to overthink and convince myself of unsound moves.  OK, I need to think about opponent's threats and that will be part of practice.  The position above is actually not bad for playing against a computer.  While white is winning it may not be simple to do so against a machine.
