Tactics training challenge

Hi, I was 1100 player few months ago (october, november), now I am about 1600-1700. I have set training plan with chess.com and it helped me a lot. I have done beginner study plan for players 1000-1400 (all videos, articles and lessons there) and  it definitely brought me over 1400. Now I am dedicating two whole months to just solving puzzles. Of course i play games in my chess club and ocassional tournaments, but I am really working on improving my tactics. Here is one things I would like to share and ask:

I have noticed that solving puzzles really helped me to find the right candidates moves, I don´t know how .. but very often I look at the position and somehow without hard thinking I see quite fast moves that are the best possible. It is like a intuition, but I have problem with one thing. I often cannot just go deep enough in the candidate move to verify if it is really the best one. Solving puzzles seems that it is not helping me so much in this. Do you have any recommendations how could I train thinking many moves ahead in candidate moves? Or do I just need to continue with the solving puzzles and I will improve in this eventually?

Thank you

Calculate 2,5 moves ahead.It can appear easy but it is not.There are a lot of variation that u need to consider.PS:of course 2,5 moves means 3moves of yours and 2 than your opponent.

thanks, but how can I train that and meassure my progress? by solving puzzles?

Puzzle is not a good exercise(at least for me)because it is written for example: mate in 3. U need to find best variations without any help,u need to search for a mate or for positional and tactical moves.I like a lot go on chessbomb site,i go on move 20-25 of a game and i stay there 10 minutes to evaluate position,i search to calculate 2,5 best moves ahead.

I thought about it and the problem with chess.com tactics might be that they are meant to be solved really fast. Usually the reward is if you solve the puzzle in less than 1minute and after that it is significantly lower. This doesn´t really give me a time to train my brain thinking many moves ahead

I think I should continue solving chess puzzles here, because it helpes me to find candidate moves really fast, it triggers my intuition and boosts my knowledge of patterns

but as you suggested I need also to solve chess problems with much more time available and in more detailed and deep way 

Exact,you found out the real essence of my answer.U very clever!
