The first game that led to an interest in me.

Hakkapeliitta 21041 - Rybka 4.1

Rybka convert the game to rook middle game (strongest part of Rybka).

Anyway, total in the game Rybka made 6 inaccuracies.

Most interesting here:

Rybka played Rac8 instead of Rae8.

Eventual mainline:

... Rae8 33. Bc2 Bb7 34. Nd5 c6 35. Nf4 Rg5 36. Rh1 Reg8 37. Kb2 c5 38. Re1 Rg3 39. Bf2 R3g4 40. Be3 c4

Looks like Rae8 is best, followed by Raf8 and Bb7, but there are many choices and black seems to have a clear advantage at this point.

Bxd5 (!) instead of Ba8.

Only one small inaccuracy that doesn't affect game result Gingko made on last move.

Fizbo plays exf7+ (quite normal move).

Fire played very well, unfortunately at finish connection stalls.

Looks weakness for Fire is midle-game phase (for most other engines opening and endgame phases).
