Tricks in 60min Chess

In this 60min game, my opponent was VERY low on time, I made a mistake playing bishop a4 and missed black's move Queen to b6. After Queen b6, my rook is trapped. I'm sure my opponent saw this as well. Best move for white is to take the knight on b7 with the rook, Queen takes back.

In this lost position for white, and black knowing rook takes b7 was the best move for white, I should have played for one last trick in the position.................. bishop c6 !!!!!! Opponent pre-moved Queen takes b6 and I would have won his queen with bishop c6!!!! I thought about this during the game but did not go for it

Lots of tricks in chess!! Be carefull!
