For example, I found there are at least 5 common actions which create beneficial potentials to gain advantages, and they are: restraint (R), interference (I), control (C), activity (A), and polarize (P) - R.I.C.A.P. for memorizing.
"Restraint" makes the opponent think/play hardly or forces them changing plans. "Interference" disconnects or destructs the defending of opponents' chess structure. "Control" creates pathways or squares for my other pieces to move in, also has similar effects from restraints. "Activity" releases the power of pieces. In other words, if pieces are hindered or restrained, they have no activities, so they can not come into the play, like being removed from the board temporarily. "Polarize" or "Concentrate" make pieces focus on the same target. I describe the action as "polarize" since the target "draws" the attacking pieces which concentrate on the target, and this kind of scenario is like the interactions between the positive the negative charges.
Moreover, 8 elements in defending are observed: shield (restraint), prophylaxis, prevent (interference), snipe (attack), move (escape / transfer), counterattack (in-between), sacrifice, and ignore. From the games I played on lichess.org, I think threatening seeds would start to grow up in the soil of the weakness which has nutrition, called momentum, to feed opponents' pieces to create an unfavored imbalance against me. In order to "see" the whole game more fast and clearly, I am considering to make a node diagram after finishing an analysis per game.
Quick recall:
Sicilian defense; Try to make a middle game with a closed-center; Rook-pawn endgame; Pawn promote to win.
For Black, move 8, 13, 20, 28 were relatively longer than other moves.
Critical moments:
There were several tipping points that could orient the game to a different scenario:
White @ Move 6 (abbr. W@m6), B@m17, B@m20, B@m22, W@m30.
