I was playing horrible last night and losing heavy material in a rapid game (20 min each). But suddenly I saw an opening when he confronted my queen with a possible trade.
Nice one. I think black came into this position because of playing the king indian defense as an opening. I am studying a bit on these opening and i read about it that it is a risky opening. The castle is vulnerable as we see in this puzzle.
What whould you have done?
