As an amateur, I prefer the Scotch game as opposed to Ruy Lopez, since I feel that White loses tempo and Black seems to gain tempo with queenside counterplay in the main line.

 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 {Bishop retreat at the expense of black gaining one queenside counterplay} b5 5. Bb3 {Another bishop retreat at the expense of black gaining a good queenside counterplay}

At the end of White's fifth move, it looks like Black is couple of tempo ahead and already has queenside counterplay going. Despite this, why is this one of (if not the most) celebrated openings? Can someone offer an explanation at the level of an amateur?

Sure black's a6-b5 come with tempo, but let's say at a very basic level, if you just compare pieces, structure and development progress, you can see that white is:

• 
  Ready to castle whereas black hasn't yet developed either kingside pieces, so at least 2 tempi away from castling. This translates into white having a safer king 1-2 tempi earlier, which means white has the upper-hand in launching some sort of attack or push.


• 
  White has developed two minor pieces that stand quite well: Knight on f3 attacks e5 and has the potential to coordinate on f7 with the bishop on b3 already eyeing black's kingside. In contrast, black has only developed a knight, one that stands defensively on c6 covering e5.
  


• Besides the e4 pawn, white has nearly kept all pawn advancement options still on the table (therefore, can opt for various pawn structures still), whereas black has made 2 additional commitments that cannot be undone, which can on the one hand, prove to have been self-inducing weaknesses, and on the other hand, be hooks (targets) for white's pawn advancements on the queenside, e.g. an a4 push, to which black has to react immediately.

These ways of reasoning can be adopted to conceptually assess nearly any opening you see, at least at a basic level.

The point on pawn commitments cannot be emphasized enough, they're the most committal moves in the game (trades come close but at least in principle a piece can be brought back to life with a promotion, but pawns cannot! :P ). Even at the highest level, for instance take a look at any of Caruana's openings in the match so far, where roughly speaking, he intentionally favours lines where he can delay unnecessary pawn moves and keep most of his options open. Examples:

Game 2:

Anyhow I think the idea is clear now! It's important to add that in all these examples, the simple fact of having moved less pawns doesn't directly or necessarily translate into having a better position, chess is never that simple or linear. Partly, specially in this examples, it is a case of style and preference (and thus the adopted openings), but on the other hand it shows you the importance of diversity in pawn structures that can still be opted for as they translate into having more choices, abundantly clear even at the highest level.

I hope these ideas have shown you why the Ruy Lopez is such a liked opening, which I have only tackled from the white side in this post, and clearly, black's side has its own merits in the Ruy Lopez compared to alternative options that are available for black against 1. e4, but that's a discussion for another time.

Note that while black gains space on the queenside, the advanced pawns offer white some opportunities later on to undermine black's pawns with a timely a4-push. Moreover, the queenside expansion doesn't develop a piece, nor does it help black to contest the center of the board. Further, white's bishop is quite a happy camper on b3, being less exposed than it would be on c4 while at the same time being basically just as influential as it would be on c4. So while white has spent 3 tempi to get the bishop to b3, black has spent 2 tempi on a queenside pawn expansion that doesn't develop a piece.

In essence, white gets to develop a piece to a very good square, while black gets to expand on the queenside, which doesn't really aid in development very much and has a potential of weakening black's position in the future. So the expansion is not without drawbacks for black.

What has Black gained by a6 and b5?

• He is no more developed than he was before those moves.


• Primarily he has removed BxN options from White.

What has White gained from a6 and b5?

• The advanced pawns are often targets for White.


• White's Bishop is now on a nice diagonal and doesn't have to worry
  about d7-d5 moves hitting it as in some lines of the Two-Knights or
  Bishops Opening (2.Bc4 and 3.Bc4 lines)

So in general your assertion that Black is gaining tempos and counter-play are completely misguided.
