puzzle rush

who agree with me that if you cannot spot a tactics in puzzle rush,  your not going to spot in the real game. 

after taking diamond membership,  my puzzle rush score has increased from 21 to 23. i pay the membership by using debit card on chess. com android app.  i don't have credit card. 

If you can't spot a tactic in tactics training, you probably won't spot it in a real game. That is part of the reason to train tactics, to learn patterns and be able to spot when some may be latent in a position and point to need to calculate a little more deeply.

Puzzle Rush is a slightly different form of training and is more to test quick pattern recognition, with a minimum of calculation, in many cases. Not seeing something there may be due more to the time element than a inability to find the tactic.

in real game i know only in specific position like king hunt that there exist tactics or combination.  any hint on how to smell tactics in normal middlegame position.  

the best i can try to get some tactics on such position is ploughing the field.  i don't know how to use tractor.  that's why i started taking interactive lesson on chess. com. 

can you suggest link on some good chess. com videos where i could improve on the above mentioned part or some general outstanding video lesson.
