fredthebear: I don't usually laugh at blunders, but this one gave me a chuckle. Always ask thyself "If I do this, what will my opponent do next?"Here is some helpful computer analysis explanation for newbies:
Using pgn4web as the PGN Viewer, point your cursor and click on the e8 square for instant, free analysis after any move that was made during the game.
My experienced eye sees a questionable move by White, so I sought the computer's recommendation to see if it agreed with me. It indicates that White would have retained an edge after 16.Rb1 instead of 16.Bd2?!. (The ?! is my evaluation of the wrong move. It is dubious, but not a disaster.)
You must choose and then Set the PGN Viewer to pgn4web for this analysis function of the e8 square to operate. This adjustment selection of the PGN Viewer is made in the long, narrow rectangle below the game score and above the kibitzer comments.
Back to the game. So, after one exchange of rooks - but not the queens - the game would be equal (=) following 17.QxRa1 Qa8 and 18.Qb1. White needed to bring either heavy piece over to the b-file instead of trading both off. It was a small but important mistake for White to allow the exchange of rooks, and then exchange queens because it improved the position of Black's second rook at the conclusion of the sequence.
Thus, the actual 16.Bd2?! and the resulting trades of heavy pieces (rooks and queens) benefits Black, who gets to control/operate on the open a-file after 18...RxQa8. White could have avoided these trades with 16.Rb1 or 18.Qb1.
20.Ne5? allowing for more exchanges was another mistake. A point and click on the e8 square for analysis indicates 20.dxc5 was best. (Ordinarily, it's not wise to triple pawns on the c-file, but in this case there are rooks along the fourth rank that make it necessary.)
After 21...NxNe5, the lateral pin on the d-pawn causes White to drop the exchange next, forcing the rook to recapture the knight instead of the pinned d-pawn.
A point and click on the e8 square for instant, free analysis is not available when using Olga Viewer. The PGN Viewer must be chosen and Set to pgn4web. You get instant, free analysis after any and every move if you wish - just point your cursor and click on the e8 square.

By the way, it is against the rules of chess for human players to write these evaluation symbols on their scoresheets during play. The official scoresheet is for recording the moves, and clock time if one so desires.
