On move 19? I couldn't really see any forcing tactic. My first instinct was to play Qg5 to try for some cheap tactics involving Bxh3.
lOOKS GOOD , but white seems to have enough to defend against tactical play at this point thus the search for a strategical Plan. Because white will certainly challenge the Rook on the 7th with (Rb1) and my backward queen-pawn attacked by his queen-bishop don't help matters.
Should be Decisive ( No Engines Please ) Black's Move.
Or Suggest a Better Plan !! What happened to my ANNOTATIONS FOR PETE'S SAKE ??????!!!!!!!!!!
