Just because there's a goal keeper doesn't mean you can't score

In my daily tactical training, I thought I had solved this exercise, only to find I missed White's defence.

 

 

I had seen the idea of getting the Black Queen to h1 and thus chose 1. ... Qe4 seeing no defence after 2. Qxh6 Qh1+ and winning the Exchange

 

 

I had a blindless in not seeing that White has Qd5 defending "through" my piece to cover the h1 square

 

Had I found the best move for my opponent, that would have lead me to find a move to stop this

 

 

For me, this must be the most difficult tactical theme. It feels very unnatural, and to be very fluent with this theme, one must inevitably be appreciative of the opponent's piece coordination

 

Had I notice 1. ... Qd5 that may have lead me to find 1. ... Bg5

 

This surely is a difficult move to find, causing interferrence to d5 as well as threatening ... d5 followed by ... Bd2. It also exploits the White Queen is overloaded protecting the invasion at h3

 

 

Weak light squares of White, with threatened invasion at h1 and h3

 

Bad piece coordination for White, with his White Queen scrambled offside and ultimately cutoff through interferrence

 

The advanced f2 pawn being Black's trump

 

The Black d-pawn threatening to advance to disrupt a defender of the d2 square

 

 

Have to improve noticing skewer" defence eg. Qd5

 

Asking yourself how to prevent a defence (and remove the goalkeeper) can answer your tactical questions
