Wikipedia gives these definitions:

<Decoy>: this is a chess tactic used to lure a piece to an unfavourable square.

<Deflect>: the inverse of a decoy (see above). Whereas a decoy involves luring an enemy piece to a bad square, a deflection involves luring an enemy piece away from a good square; typically, away from a square on which it defends another piece or threat.

In other words, a decoy pulls a piece onto a bad square; a deflection pushes a piece away from a good square.

I couldn't find a separate definition of "distraction", which seems to be another way of saying "deflection".

Or perhaps it is when your female opponent wears a low-cut blouse.

Or your male opponent gently lifts one buttock off the chair and ... ahem ... breaks wind.

Unfortunately for me, the latter happens far more frequently than the former.>

This reminds me of something Kasparov said about Karpov. Something about having played Karpov so often that he was familiar with all his smells.

First of all, yes, I understand the purpose of advancing f4 whilst mantaning control over g4 and opening the scope of the light-squared bishop.

But after facing over and over kingside fianchettos against my patzer buddies, 14.h4 seems such a natural move.

My intention is to sacrifice the little indian (H is for "hack", as I've read once) with 15.h5 ♘xh5 16.f4, opening the light-squared bishop fire right when it's needed.

I haven't run it through Fritz and have no practical intentions of doing so, just want to hear what you think about this.

I have skipped Black's move 14... for practical reasons, 14...h5 could disturd my immediate plans, one could attempt 15.f4 but I believe White has enough time for the ♘f1-♗d2-♘e3-♖dg1 followed by f3-f4 maneuver.

White's queenside structure strikes to me as a blockadable formation.

Even though we're open-minded, Rfa8 is obviously not forcing the win as Ra1+, which allows W to delay the loss via Qd8+ which could not save the loss.

But in this case it's not the best for another reason. 29...Ra1+ leaves White no choice, which means Black has less to calculate and fewer chances to make a mistake.

Let's change the position just a little bit:

29. ... Ra1+
30. Kxa1 Qa4+
31. Kb1 Qa2+
32. Kc1 Qa1+
33. Kd2

Has this done any good? It's a very easy position to visualize.

34. ... Qxb2+
35. Qc2

So far Black's moves have been excruciatingly forced. Now
