C24 Bishop's Opening: 2...Nf6 (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.O-O Nf6 5.d3 d5 6.exd5 Nxd5)

This one was played in the first round of a tournament called 2014 August Banded Threesomes at Red Hot Pawn. Players were divided into seven three player groups and one four player group as there was uneven number of players joining the tournament. As only the winner advances or in a case of a tie more than one will advance, this tournament went in a interesting way. In four of the groups only one player advanced but in the other four most players advanced to the second round. In three of those groups two out of three advanced and in one of them came a three-way tie, so all the players from that group advanced to the next round. In my group, me and KellyJay were the ones to advance to the second round. The time control in this tournament is three days per move plus seven days that are in the timebank. This tournament started on August 22nd 2014. The first position I want to highlight, is the one after 31...Rc6. In that position KellyJay played 32.Kf2, which created even more problems to my opponent than he or she faced before it. The idea of doubling the rooks on the c-file and taking the knight from e4 with the bishop, allowing the rook to go all the way to c3 is a similar plan I used in one of the games I shared yesterday. Unfortunately I did not go for that plan in this game and my advantage quickly vanished.

The second position of interest is the one after 37...Rxc2. KellyJay chose to play 38.Ra7+, which was placed the rook one square too far. At a6 the rook would have attacked the pawn on b6 and maybe lured my rook back from c2 to protect the pawn and even though I have an extra pawn, the position would be likely even since I can't really make use of that pawn. In the game continuation my rook went from c2 to c7 to block the check and had my opponent now gone for the move Ra6, I could protect the pawn by placing my rook to b7. It would have been a better way to protect the pawn, at least according to Stockfish 8 64 POPCNT at depth 32.

I was able to increase my advantage to a winning one, but like so many times before, with one horrible decision, 50...Ra2, my chances of winning the game became nonexistent and equality was restored to the position. I thought that two extra pawns would be enough to win the game, so I wanted to trade rooks, but KellyJay did have an easy way to get back material. It can be seen in the game continuation 51.Rxa2 Bxa2 52.gxf6 gxf6 and next the move 53.Ne4, which attacked both the undefended bishop on a2 and the undefended pawn at f6.

While messing up the winning advantage, so that draw is the most likely outcome can annoy a player, it does not compare to the realization that within few moves I went from a winning position to first an even position and then to a lost position. With two consecutive bad moves 55...Ke7 and 56...Kf8, I could have lost the game. The first move was bad because of the reply f6+, and the second because of the move 57.Rc2, which my opponent did not play. KellyJay decided to threaten my pawn on e5 with the move 57.Rf5, but I could easily defend that position by moving my rook to b5. My other option would have been to counterattack the pawn on d3 by placing my rook to b3.

Other bad moves were seen during the remainder of this game, but the game deciding blunder was my opponent's 64th move Kh4. It was too slow of a move, because I could just advance my c-pawn and force my opponent to defend against it.

KellyJay had no time to try and push the f-pawn when my c-pawn had reached the third rank because my opponent needed to make preparations for it. I, on the other hand, could have just pushed the pawn forward. Therefore after 64...b3, KellyJay had to play 65.Rf2, but the outcome of the game was already clear, I was going to win.
