I'll post here with brief comments.
GAME 1 - early tactical skirmishes see most of the pieces come off and we enter a rook and opposite coloured bishops endgame with each side having a pawn majority on opposing flanks. Komodo has the advantage due to Stockfish's lone kingside pawn being vulnerable against the further advanced enemy forces. Stockfish desperately tries to hold the game by giving up its b-pawn to advance the passed a-pawn created, but there is no salvation. Komodo goes 1-0 up in the match.
GAME 2 - although the game developed differently, there were again early tactical skirmishes leading a relatively early endgame. However, this time neither side had an advantage and a draw played out.
GAME 3 - early tactics and an early endgame for the third successive time. Komodo is again the aggressor in creating connected passed pawns, but Stockfish retaliates immediately on the other flank to keep the balance. A draw eventuates.
GAME 4 - although we see opposite side castling, most of the heavy artillery has come off beforehand. It isn't too long before we see a bishop and pawns v knight and pawns ending. Unfortunately for Stockfish the bishop lacks teeth and Komodo easily holds the draw. Komodo still with a 1-0 match lead.
GAME 5 - although we see opposite side castling in a Sicilian, neither side can see a way to create an attack against the enemy king. Eventually Stockfish sacs the exchange for a couple of extra pawns in an attempt to inject life into the game. However, it is Komodo that retains a tiny edge going into the quickly resulting ending. The eventual draw seems a fair result.
GAME 6 - Komodo gives up a pawn to keep the Stockfish king from castling. Tactics quickly follow, but this time it's Stockfish coming out holding a small edge. The material imbalance in the endgame makes play interesting until liquidations take us into a drawn rook and pawn ending. Komodo still leading 1-0.
GAME 7 - there was some reasonably interesting opening play in a drawish line of the Alekhine's, but the resulting position with all pawns on one side of the board always hinted that a draw would be the outcome.
GAME 8 - in the return encounter, we had to wait until the rook and opposite coloured bishops ending before there was some lively play. However, a draw always seemed the inevitable result yet again. Komodo still leads 1-0.
GAME 9 - Stockfish builds up a massive kingside attack. Komodo defends stoutly, but goes the exchange down in the process of survival. Stockfish carries this material advantage through into the endgame and cashes in to take the full point. The match is now level at 1-1.
