Handling Lower Rated Opponents

there are lots of such lower rated players who play such openings for drawing against higher rated opponents.

This is one of the example my opponent played vienna game and even after following all book moves and not doing any mistakes at the 19 move It was easily drawable for a lower rated player so I took a risk by playing 19.g6 which is a mistake but only by that move I won the game.

These days many lower rated players play openings like Vienna game, Bishops Opening, Four Knights Game Some Lines In scotch. in these openings if a experienced lower rated decides to have a draw he can force it against higher rated.

Magnus abandoned the 2900 mission because of this reason.

What should we do against such lower rated players?

Lower-rated players often play for exchanges and simplifications to reach equal, drawish positions. Try to avoid unnecessary trades. Keep pieces on the board, particularly queens, to retain complexity and create winning chances later in the game.

Correct

but in specific openings there the drawish exchanging line is forced

In some lines a skilled player, especially if they have white, can reasonably push for a draw against a higher rated player. Seems like two ways to avoid this as black are to play sub-optimal lines or to play openings with less drawing chances (e.g., Sicilian).

At my level, though, this isn't a problem!

what are sub obtimal

Moves that are not the best. In this case, playing a less good or dubious move in order to reduce the chances of a draw. Your 19 ... g6, for example.

Handling lower rated opponents - you blunder your queen and you hope that they blunder it back? Interesting strategy.

It seems like you already know what to do. Play a move that isn't a blunder but just inaccurate enough to give both chances sides.

even if it gives him the better position

9, I don't think he's talking abt that extreme

how to fight scotch ambitiously from black it gives good drawing chances for the lower elo opp ion the white side??

This is exactly what happened in the example game.

But somtimes it backfires !!

First of all,they don't play for a draw.They want to beat u too with same intensity as yours.Also they play their best prepared line many times that they usually do with similar rated opponents too.If u can't outplay them in that line its your skill issue,just accept it, move on& improve.playing lines u know better than your opponent is always helpful even when u playing a higher rated opponent than u.

if in the example game instead of 22.Ng3 if he would had played gxh7 it was over
