fianchettos are decent especially for white but become hard as the bishop is hardly backed up and a rook is behind diagonally. that g3/7 b3/7 pawn move can leave your rook wide open for an opposing bishop. generally exchanging is a useful tool you can sometimes win a peice this way and almost always win information.
now other strategies. keep your opponents guessing.
now this isnt a perfect example but if your opponent leaves their queen hanging like this lets say. the queen can obviously see the bishop so they expect the queen to be taken by the bishop. however if you take with knight here that is a level of unpredictability that you can utilize. this position will probably not happen but there are so many cases similar where i utilize this to win.
scouting. especially with knights. move your knights to scout out squares recently captured on or that you think could be important. its important to note this can be done with any piece but is riskier with a queen or rook.
make inferences and analyze their pawns. mark where there pawns are this is so helpful and ive been doing this. not only will it give you information but it can help you deduce where they castled their plans even piece location.
try to double or even triple defend as much as you can especially towards the center. it is not uncommon for there to be up to 3/4 exchanges consecutively on a single square. if youre trading material you want to be the one with the last laugh. also capture with lowest value pieces first as a general rule.
opening theory for fog is hard seeing as you cant actually observe all your opponents moves. keep your peices defended develop towards the center and keep your king safe are the biggest parts. ive been using c6/5 often as black or white and love it. then i tend to open up with e3 with the intention of d4 and bringing my bishop toward the center. this allows for a decently early kingside castle but at the expense of it being somewhat obvious where your king ends up.
as black 1...nc6 is also fairly strong after that i like to push e4 to keep that pawn defended.
if you can trade queens with equal material on the board GENERALLY you should. not always though. but it gives you great amounts of information and theres always a small chance they were dumb and left it hanging.
im sure there is more im either not thinking of or too inexperienced to really pick up on but as a fairly strong player i can say these are very important things to utilize and then master
Fog of war is a chess variant in which you only see the squares to which your pieces can move. And so I was wondering, what is the best strategy ? Fianchettos must be good, bescause you see the whole diagonal. Also exchanging in the opponent's territory is good because you might get a glimpse of the surrounding pieces.
