B92 Sicilian Najdorf: 6.Be2 (1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 d6 5.Be3 e5 6.Nb3 Nf6 7.Nc3 Be6 8.Be2 Be7 9.O-O O-O 10.f3 a6)

This game was previously seen on the post Sicilian Defense: Open #3. That post no longer exists with that name, it is now called B32 Sicilian: Löwenthal and Kalashnikov Variations (7...Nf6) due to the way I now name the openings played in the games. The rest of the post is seen pretty much the same way as it was originally shared except that now the diagrams are living ones, meaning you can make moves in them.

This game was played in the "paweljaniak's mini-tournament I". This was the first mini-tournament in which I have been on second place in the final standings. I have now finished 5 mini-tournaments. In addition to this second place finish, I have been on third place twice, I was on 5th place once and in one of the mini-tournaments I was on 9th place in the final standings. In this tournament I was able to gather 8.5 points in 12 games. One of the games was never played though, so in the games I played I gathered 7.5 points out of 11 games. Paweljaniak won his tournament and he was able to gather 11 points in 12 games. My opponent was third in the final standings and was able to gather 8 points in 12 games.

The point at which the game started to go downhill for ledzepp was when my opponent played 14...Ne8 in the position below. 14...d5 seems like a logical move to make. Ledzepp would get rid of the backward pawn on d6 and increase the scope of the bishop on e7 a little bit.

The move my opponent played is too passive. The only reason why 14...Ne8 would make sense is that ledzepp wanted to play 15...f5. 14...d5 would have likely accomplished the same idea because I would have taken on d5 with a pawn and then ledzepp would play Nxd5, allowing the f-pawn to move. The difference is that the knight would be better placed. I replied with 15.Nd5 and due to that move I only had a small advantage. The engine thinks that I should have played 15.g3 instead. I am not really sure what the point of playing 15.g3 is, but the engine seems to like it. When we reached the position shown below, my opponent took another wrong turn and played 19...Nd8.

The final mistake after which my opponent's position was completely lost was played in the position shown below. Ledzepp should have played 29...Rd7, but even in that case, the game would have been a struggle for my opponent. In the game ledzepp played 29...Ne3.

I replied with the only move that allows me to fight for the win, 30.Qxe5. It was easy enough to spot the undefended pawn on e5 and I take the material if I can't see any good reason against it. The game ended in a few moves to my opponent's resignation.

Game number two. The team match held at Chess.com called Zamboanga was played between Philippine Critical Movers and CHOCOLATE II on 25 boards and I played on board 3 for CHOCOLATE II. I won both my games on time. The match ended with a score of 30.5 - 19.5 in favor of Philippine Critical Movers. The first mistake of significance was played by my opponent on move 15. Lexis_bruce played 15...Nc5, which may have seemed like a good move, but I could have taken the knight with my bishop and I would have ended up with a protected passed pawn on d5.

I was too protective of my bishop pair and moved one of my bishops to c2. Lexis_bruce then played the interesting, but a bad move 16...b5. It gave me another chance to seize a clear advantage with the continuation starting with the move 17.cxb5, but again I chose to play the more passive move 17.b3. The game then continued up to the final move of the game 23.Nb1 in an equal way.
